Simini Surgery Review: Small Animal Edition

In this episode of the Simini Small Animal Surgery Podcast, we explore the orthopedic research from the August 2026 issue (Issue 6) of Veterinary Surgery, where two studies focus on restoring normal biomechanics in challenging orthopedic cases, from feline corpus ilium fractures to canine patellar luxation associated with abnormal tibial torsion.  One study compares a modified clamp rod internal fixation system with conventional locking plates for feline ilial fractures, while the second examines proximal tibial detorsional osteotomy as a way to correct the underlying rotational deformity responsible for patellar maltracking. In this episode: ✅ Saylak et al. conducted a prospective clinical study of 36 cats with corpus ilium fractures, comparing conventional locking plates with a modified clamp rod internal fixation (MCRIF) system. All fractures ultimately healed, but the MCRIF group demonstrated better radiographic healing at 45 days, less pelvic canal narrowing, and no screw loosening, compared with a 22.2% screw-loosening rate in the locking plate group. The adjustable clamp design allowed screws to be placed at a precise 90-degree angle to the cortex, maximizing screw purchase in the narrow, relatively spongy feline ilium. The rod also functioned as a rigid bridge, maintaining anatomic alignment without drawing the fragments inward toward a flat plate, potentially reducing the risk of clinically significant pelvic canal narrowing.  The discussion also highlights the importance of surgical site management at closure in complex orthopedic procedures involving greater tissue manipulation and implanted hardware. The episode examines how reinforcing the lavage protocol may help address bacterial contamination that mechanical fixation alone cannot control.  ✅ Petazzoni et al. reported outcomes following proximal tibial detorsional osteotomy (PTDO) in dogs with patellar luxation associated with abnormal tibial torsion. Across 53 stifles, the procedure restored normal patellar tracking in 96% of cases, with 96% also achieving full or acceptable limb function. Rather than simply repositioning the tibial tuberosity, PTDO addresses the underlying rotational deformity of the proximal tibia. The technique is mechanically demanding because of persistent traction from the patellar tendon, making rigid fixation and precise plate contouring essential. Although the overall complication rate was 33%, major complications occurred in only 11% of cases and were predominantly implant-related, emphasizing that successful correction depends heavily on meticulous mechanical execution.  Together, these studies reinforce a fundamental principle of small animal orthopedics: successful fixation is not simply about holding bone together. It is about identifying and correcting the mechanical problem that caused instability or malalignment in the first place.  🎓 Journal Articles Discussed Saylak  et al. — Locked plate versus modified clamp-rod internal fixation for feline corpus ilium fractures: A comparative clinical study Petazzoni et al. — Clinical outcomes and complications after proximal tibial detorsional osteotomy for patellar luxation in dogs: A multicenter retrospective study 📚 From the August 2026 Issue (Issue 6) of Veterinary Surgery  🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the May 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring three studies that reveal how hidden pathology often lies beneath seemingly normal clinical findings.  From subtle elbow incongruity in medial coronoid disease to standardizing stress radiography for hip dysplasia and identifying silent gastrocnemius tendon injuries in canine athletes, these papers emphasize the importance of looking beyond what is immediately visible. In this episode: ✅ Scharpf et al. — Used CT imaging to evaluate radioulnar congruity in dogs with medial coronoid disease (MCD). Although the medial compartment often appeared anatomically congruent, the authors identified significant lateral and central radioulnar incongruity, suggesting that many cases of MCD may actually represent a joint-wide biomechanical disorder rather than an isolated medial lesion. These findings help explain why some dogs continue to experience lameness despite technically successful arthroscopic treatment focused solely on the medial compartment.  ✅ Vandekerckhove et al. — Quantified the force required during passive stress radiography to accurately assess canine hip laxity. Under standardized sedation, 90% of hips reached maximal diagnostic laxity at approximately 80.5 Newtons (about 8.2 kg of force). The study provides an objective benchmark that may improve consistency between clinicians while reducing false-negative screening examinations caused by inadequate applied force.  ✅ Vannini et al. — Investigated gastrocnemius tendon origin (TGMO) injuries in actively competing Border Collies. Despite owners reporting no lameness, more than half of the dogs demonstrated pain during palpation, while ultrasonography revealed tendon abnormalities in approximately 85% of cases. The study showed that direct palpation of the lateral fabella was the most clinically useful screening tool, emphasizing that many athletic dogs may develop significant tendinopathy long before overt lameness appears.  Together, these studies reinforce an essential orthopedic principle: successful diagnosis depends on recognizing pathology before it becomes clinically obvious. 🎓 Journal Articles Discussed Scharpf et al. — Assessment of the Conformation of the Radioulnar Joint Comparing Dogs with and without Medial Coronoid Disease Vandekerckhove et al. — Quantifying the Stress in Stress Radiography to Determine Sufficient Laxity of the Coxofemoral Joint in Sedated Dogs Vannini et al. — Prevalence of Tendinopathy of the Gastrocnemius Muscle Origin in a Cohort of Sound Border Collie 📚 From the May 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we begin our orthopedic coverage from the May 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring three studies focused on making better clinical decisions through objective measurement.  From synovial biomarkers for joint disease, to surgical stabilization of degenerative lumbosacral stenosis, and evidence-based rehabilitation exercises, these papers demonstrate how data—not assumptions—can improve diagnosis, surgery, and postoperative recovery. In this episode: ✅ Beer et al. — Evaluated synovial fluid C-reactive protein (CRP) as a diagnostic biomarker for canine joint disease. Dogs with osteoarthritis demonstrated very low synovial CRP concentrations (median 1.2 mg/L), while dogs with immune-mediated polyarthritis (IMPA) and bacterial infective arthritis showed markedly elevated values of approximately 60–65 mg/L. Although CRP reliably distinguished non-inflammatory osteoarthritis from inflammatory joint disease, it could not differentiate septic arthritis from immune-mediated disease, reinforcing the continued importance of synovial cytology, culture, and clinical judgment when evaluating painful joints.  ✅ Van der Brink et al. — Compared standalone intervertebral cages with cages combined with pedicle screw and rod fixation (PSRF) for canine degenerative lumbosacral stenosis. Both techniques achieved similar long-term clinical outcomes, with approximately 64–65% of dogs returning to full function. However, adding PSRF reduced cage subsidence from 75% to 33%, improved radiographic fusion, and decreased temporary neurologic complications by providing greater construct stability during bone healing.  ✅ Ramos et al. — Used inertial motion sensors (IMUs) and surface electromyography (sEMG) to objectively measure muscle activation during rehabilitation exercises on progressively unstable platforms. While unstable "peanut" exercises increased thoracolumbar instability by 42–60%, they unexpectedly reduced activation of the epaxial muscles and biceps femoris, while dramatically increasing rectus abdominis recruitment. The findings suggest rehabilitation equipment should be selected based on which muscles require strengthening, rather than assuming greater instability universally improves core activation.  Together, these studies reinforce an important clinical principle: better orthopedic outcomes come from measuring the right variables—and understanding what those measurements truly mean. 🎓 Journal Articles Discussed Beer et al. — Synovial Fluid C-Reactive Protein as a Biomarker in Osteoarthritis, Immune-Mediated Polyarthritis and Bacterial Infective Arthritis  Van der Brink et al. — Comparison of Stand-Alone Cage versus Intervertebral Cage with Pedicle Screw and Rod Fixation in Dogs with Degenerative Lumbosacral Stenosis Ramos et al. — The Effect of Progressively Unstable Equipment Used in Canine Fitness and Rehabilitation on Standing Postural Control and Muscle Activity 📚 From the May 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we conclude our orthopedic coverage from the March 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring two studies that emphasize an essential surgical principle: successful orthopedic reconstruction depends on understanding anatomy—not simply repairing bones.  From complex craniomaxillofacial trauma in cats to an alternative surgical approach for canine total ankle replacement, these papers demonstrate how thoughtful preoperative planning and detailed anatomical knowledge can dramatically improve patient outcomes. In this episode: ✅ Weichert et al. — A retrospective CT study of 48 cats with craniomaxillofacial trauma following high-rise syndrome or motor vehicle accidents. Although mandibular fractures occurred in 40 cats, the authors found that 75% of patients (36/48) had injuries involving multiple functional systems. Notably, all cases of nasal airway obstruction were associated with oral cavity injuries, while 25 cats sustained fractures of the pterygoid hamular process, creating occult airway compromise despite minimal external soft tissue damage. The findings highlight the importance of CT-based evaluation and comprehensive surgical planning that addresses airway, mastication, vision, and temporomandibular joint function simultaneously.  ✅ Zingel et al. — A cadaveric study evaluating a lateral surgical approach for canine total ankle replacement (CTAR) when the standard medial approach is not feasible. Both approaches achieved excellent implant positioning, with 96% of bone-implant interfaces measuring less than 1 mm. Although the lateral approach increased angular laxity (15.5° vs. 9.5°) and required fibular osteotomy with meticulous protection of the lateral collateral ligament, overall joint stability remained acceptable. The authors conclude that the lateral approach represents a valuable alternative for revision cases or patients with severe medial scarring, while emphasizing the importance of precise center-of-rotation post placement and soft tissue preservation.  Together, these studies reinforce a central lesson in orthopedic surgery: the best reconstruction begins with understanding anatomy in three dimensions before making the first incision. 🎓 Journal Articles Discussed Weichert et al. — Assessment of Fracture Distribution and Involvement of Functional Systems Following Craniomaxillofacial Trauma in 48 Cats Zingel et al. — Implantation of a Canine Total Ankle Replacement Prosthesis Using a Lateral Surgical Approach is Accurate and Leads to a Stable Joint  📚 From the March 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we conclude our orthopedic coverage from the March 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by examining how better surgical instrumentation can improve precision, consistency, and patient safety.  One study evaluates an ergonomically redesigned cup impactor for canine total hip replacement, while the second demonstrates how patient-specific 3D-printed drill guides may transform feline spinal stabilization. In this episode: ✅ Mancusi et al. — A cadaveric study comparing a prototype ergonomic acetabular cup impactor with a conventional impactor during Zurich cementless total hip replacement. Among novice surgeons, the prototype significantly improved the angle of lateral opening (ALO), reducing the mean placement from 48.9° with the standard impactor to 43.2°, much closer to the ideal 45° target. However, the improved instrument did not improve cup retroversion, reinforcing that while better tools can reduce mechanical errors, accurate interpretation of anatomic landmarks remains essential for successful THA.  ✅ Rigo et al. — Evaluated patient-specific 3D-printed drill guides for thoracolumbar pedicle screw placement in cats. Across 126 pilot holes, the guides achieved an overall 91.2% safe placement rate, including 100% accuracy within the thoracic spine. Importantly, all breaches occurred laterally, with zero medial breaches or spinal canal violations, demonstrating that patient-specific guides can substantially improve safety while allowing a less invasive dorsal surgical approach. The study also reports the first successful clinical application of this technique in a feline patient, highlighting its potential for future spinal stabilization procedures.  Together, these studies demonstrate that the future of orthopedic surgery isn't simply better implants—it's smarter instrumentation that helps surgeons consistently perform at a higher level. 🎓 Journal Articles Discussed Mancusi et al. — Comparison between Two Zurich Cementless Total Hip Replacement Cup Impactor Types in the Accuracy of Cup Positioning: An In Vitro Study Rigo et al. — Feasibility and Accuracy of Pedicle Screws in the Feline Thoracolumbar Spine 📚 From the March 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we begin our orthopedic coverage from the March 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by examining how small technical decisions can profoundly influence orthopedic outcomes—from postoperative care to implant manufacturing and intraoperative accuracy.  This episode explores whether routine postoperative bandaging is truly beneficial in cats, how 3D-printed locking plates may reshape the future of patient-specific implants, and a novel device designed to improve acetabular cup positioning during canine total hip replacement. In this episode: ✅ Clayton et al. — A multicenter retrospective study of 152 cats undergoing clean orthopedic procedures evaluated complications associated with postoperative external coaptation. Overall, 68.4% of cats developed bandage-associated complications, and those receiving rigid splints were 3.4 times more likely to experience severe complications than cats managed with soft padded bandages alone. Cases included pressure necrosis, implant exposure, osteomyelitis, and even digit amputation. The findings suggest that when rigid internal fixation provides adequate stability, routine postoperative splinting may introduce unnecessary risk rather than additional protection.  ✅ Kang et al. — Investigated whether locking screw threads can be manufactured directly into 3D-printed titanium plates, eliminating the need for expensive post-machining. When printed in a 0° horizontal orientation, directly printed locking threads achieved push-out strength equivalent to commercially machined plates. However, vertically printed implants demonstrated significant thread defects, and insertion torque proved critical—100% of printed threads failed when tightened to 2.0 Nm, while 1.1 Nm provided reliable fixation. The study highlights how implant manufacturing parameters and surgical technique must evolve together as patient-specific implants become more common.  ✅ Karlin et al. — Evaluated the Cup Position Assessment Device (CPAD), a 3D-printed intraoperative guide designed to objectively measure acetabular cup orientation during canine total hip arthroplasty. Using embedded radiopaque crossbars and intraoperative radiographs, the device measured the angle of lateral opening (ALO) with remarkable accuracy—within approximately 1.1° of the true angle. Although version measurements remain limited by implant overlap on radiographs, the CPAD represents an important step toward objective intraoperative implant positioning and reducing postoperative luxation risk.  Together, these studies reinforce an important orthopedic principle: better outcomes often come from improving the small details that surround surgery—not just the operation itself. 🎓 Journal Articles Discussed Clayton et al. — Incidence of Bandage-Associated Complications in Cats following Clean Orthopaedic Procedures: A Retrospective Study of 152 Cases Kang et al. — Feasibility of Integrating Locking Plate System into Additively Manufactured Implants: A Mechanical Comparison of Three-Dimensional-Printed and Machined Locking Hole Threads Karlin et al. — In Vitro Evaluation of a Device to Assess Acetabular Cup Position by Sagittal Plane Radiography 📚 From the March 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the January 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by challenging two common assumptions surrounding timing and surgical planning.  One study investigates whether orthobiologic injections administered immediately after elbow arthroscopy actually remain inside the joint, while the second demonstrates that double pelvic osteotomy (DPO) plates consistently produce less acetabular rotation than their labeled angle, changing how surgeons should approach implant selection. In this episode: ✅ Rustemeyer et al. — A cadaveric CT study evaluating contrast retention following elbow arthroscopy. Compared with simple arthrocentesis, elbows undergoing arthroscopy demonstrated immediate postoperative extravasation, resulting in an estimated 64.3% dilution of injected fluid. The findings suggest that orthobiologics such as PRP or stem cell therapies administered immediately after arthroscopy may largely escape into the surrounding soft tissues rather than remaining intra-articular. Delaying injections until portal sealing occurs may substantially improve therapeutic delivery.  ✅ Trommelmans et al. — A CT-based retrospective study measuring the true acetabular rotation achieved during double pelvic osteotomy. Across 49 hips, every plate angle consistently underperformed its nominal correction. Thirty-degree plates produced a median correction of only 23.4°, 25° plates achieved 16.7°, and 20° plates achieved approximately 15°. The study demonstrates that surgeons should anticipate 5–8° of lost rotation due to pelvic elasticity and soft tissue tension, recommending that 7–10° be added to preoperative planning measurements when selecting implant angles.  Together, these studies emphasize that successful orthopedic surgery depends not only on technical execution, but also on understanding what happens immediately after surgery—and how living tissues respond to implanted hardware. 🎓 Journal Articles Discussed Rustemeyer et al. — Extravasation of Intraarticular Fluid Injection Following Canine Elbow Arthroscopy: A Cadaveric Study Trommelmans et al. — Effect of Double Pelvic Osteotomy on Dorsal Acetabular Rim Angle Using Computed Tomography in 27 Dogs 📚 From the January 2026 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we conclude our orthopedic coverage from the November 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring three studies that examine how precision, technology, and long-term adaptation influence orthopedic success. From a novel approach to cementless total hip replacement, to patient-specific drill guides for feline sacroiliac luxation repair, and the surprising long-term outcomes of tibial tuberosity avulsion fractures, these studies challenge conventional assumptions about fixation, healing, and postoperative function. In this episode: ✅ Arias et al. — Evaluated an undersized cementless femoral stem coated with biphasic calcium phosphate (BCP) as an alternative to traditional cemented total hip replacement. While dogs with undersized stems experienced slower early recovery and mild transient lameness, functional gait analysis demonstrated equivalent outcomes by four months postoperatively. The BCP coating promoted biological fixation through osteoconduction and osteoinduction, potentially reducing the risk of intraoperative femoral fissures associated with aggressive press-fit stem placement.  ✅ Scortea et al. — Compared 3D-printed drill guide technology with fluoroscopy-guided minimally invasive osteosynthesis (MIO) for feline sacroiliac luxation repair. Patient-specific guides achieved 92.9% adequate sacral bone purchase, compared with 64.3% for traditional MIO, while dramatically reducing cortical breaches and screw malposition. Although the guides required additional planning time and an open surgical approach, the study demonstrated substantial improvements in implant accuracy and safety.  ✅ Zweig et al. — Investigated long-term outcomes following tibial tuberosity avulsion fractures (TTAF) after skeletal maturity. Surgical fixation resulted in dramatic radiographic changes, including a 15–19° reduction in tibial plateau angle and distal patellar displacement. Despite these alterations, every surgically treated dog achieved excellent functional outcomes with no lameness or instability. In contrast, one-third of conservatively managed dogs developed severe medial patellar luxation, reinforcing the importance of maintaining extensor mechanism alignment during healing.  Together, these studies remind us that orthopedic success is not always defined by perfect anatomy—but by achieving durable function through thoughtful planning and biologic adaptation. 🎓 Journal Articles Discussed Arias et al. — Kinetic and Kinematic Gait Analyses of Dogs with Undersized Cementless Stems (Biphasic Calcium Phosphate Coated) versus Cemented in Total Hip Replacement Scortea et al. — Comparative Analysis of 3D-Printed Drill Guides and Minimally Invasive Osteosynthesis in Feline Sacroiliac Luxation: A Cadaveric Study Zweig et al. — Treatment Outcome and Radiographic Appearance of Healed Tibial Tuberosity Avulsion Fractures in Skeletally Mature Dogs: 21 Cases (2016–2023)  📚 From the November 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the September 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by examining how biology and biomechanics shape long-term orthopedic outcomes in small dogs. One study challenges assumptions about meniscal injury prevalence in toy-breed dogs with cranial cruciate ligament disease, while the second explores how growth itself may become a powerful ally in the treatment of proximal tibial physeal fractures. In this episode: ✅ Kikuchi et al. — Used arthroscopy to evaluate the incidence of medial meniscal injury in toy-breed dogs weighing 5 kg or less with cranial cruciate ligament rupture. The authors identified meniscal injury in 36.3% of affected stifles, demonstrating that significant meniscal pathology remains common even in very small patients. Yorkshire Terriers showed particularly high rates of complete cruciate rupture and meniscal injury, with over 55% of Yorkies affected. The study highlights the importance of thorough meniscal assessment, especially in dogs with complete ruptures, higher relative body weight, and severe lameness.  ✅ Turner et al. — Evaluated postoperative changes in tibial plateau angle (TPA) following repair of Salter-Harris Type I and II proximal tibial physeal fractures. Across 32 dogs, the authors observed a mean 5.89° reduction in TPA during early healing, demonstrating that significant dynamic correction occurs after surgery. Interestingly, adding a tibial tuberosity tension band did not significantly affect correction, suggesting that cranially placed K-wires alone create sufficient temporary physeal tethering to guide growth and level the tibial plateau over time. Together, these studies remind us that successful orthopedic surgery requires understanding not only the injury itself, but also how biology continues to influence outcomes long after the procedure is complete. 🎓 Journal Articles Discussed Kikuchi et al. — Incidence of Medial Meniscus Injury Detected by Arthroscopy in Toy Breed Dogs (≤5 kg) with Cranial Cruciate Ligament Rupture Turner et al. —Tibial Plateau Angle Changes following Repair of Salter–Harris Type 1 and 2 Fractures in Dogs 📚 From the September 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the July 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by examining how a deeper understanding of anatomy and biomechanics can fundamentally change surgical planning.  One study introduces a novel method for evaluating tibial torsional deformity in dogs with medial patellar luxation, while the second explores a promising bone-preserving alternative to traditional total hip replacement. In this episode: ✅ Isono et al. — Investigated tibial torsional malalignment in small-breed dogs with medial patellar luxation (MPL) using advanced CT analysis. The authors introduced the Proximal Tibia Metatarsal Angle (PTMTA), a new measurement designed to quantify rotational deformity throughout the entire hind limb. Normal dogs demonstrated a PTMTA of approximately 7 degrees, while Grade IV MPL patients averaged 32.8 degrees, with some exceeding 40 degrees. The findings suggest that severe MPL may be driven by substantial tibial rotational deformity, emphasizing the importance of evaluating the entire limb when planning corrective osteotomies.  ✅ Perez Neto et al. — Evaluated a novel short-stem hip resurfacing arthroplasty (HRA) implant as a potential alternative to conventional total hip replacement. Using cadaveric femurs from large-breed dogs, the authors demonstrated that although the implant reduced maximum load capacity by approximately 22%, implanted femurs still withstood forces exceeding six times body weight before failure. Importantly, fractures occurred in the same location as intact femurs, suggesting that the implant preserved natural load transmission patterns while maintaining substantial mechanical strength.  Together, these studies demonstrate that better orthopedic outcomes begin with understanding the underlying mechanics of the limb—and sometimes preserving anatomy may be just as important as replacing it. 🎓 Journal Articles Discussed Isono et al. — Tibial Torsion Malalignment in Small Dogs with Medial Patellar Luxation Perez Neto et al. — Biomechanical Evaluation of a Femoral Implant for Hip Resurfacing Arthroplasty in Dogs: An Ex Vivo Study 📚 From the July 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the July 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring how seemingly small surgical decisions can have major biomechanical consequences.  From preserving partial cruciate ligament remnants during TPLO to modern fixation strategies for tibial tuberosity transposition and the persistent challenge of stress concentration in locking plates, these studies provide practical insights for improving surgical outcomes and reducing complications. In this episode: ✅ Almeida et al. — Investigated whether transecting the remaining fibers of a partially ruptured cranial cruciate ligament during TPLO influences postoperative patellar ligament thickening or shortening. Evaluating 56 stifles, the authors found no difference in postoperative patellar ligament changes between dogs whose remnants were transected and those whose remnants were preserved. Importantly, preserving the residual ligament may provide ongoing biomechanical support by limiting cranial tibial translation during gait and potentially reducing future meniscal injury and osteoarthritis progression.  ✅ Eskelinen et al. — Evaluated a locking plate and pin fixation technique for tibial tuberosity transposition (TTT) in 65 medial patellar luxation surgeries. The technique achieved resolution of lameness in all patients and successful correction in 64 of 65 stifles. In cases where the surgical protocol was followed precisely, there were zero tibial tuberosity fractures, avulsions, or luxation recurrences, highlighting the importance of rigid fixation and meticulous implant placement.  ✅ Hawker et al. — Examined whether locking head inserts (LHIs) improve the mechanical performance of locking compression plate constructs. Despite testing constructs with up to nine inserts torqued to 4 Nm, the authors found no measurable improvement in plate strain, construct stiffness, or compressive displacement. The findings challenge the assumption that filling empty combi holes strengthens plate constructs and reinforce the importance of thoughtful plate selection and working-length management instead.  Together, these studies emphasize a central orthopedic lesson: sometimes the best surgical decision is not adding more hardware—but understanding which details actually matter. 🎓 Journal Articles Discussed Almeida et al. — Effect of Cranial Cruciate Ligament Transection during TPLO on Patellar Desmitis in Dogs with Partial Cranial Cruciate Ligament Rupture Eskelinen et al. — Outcome and Complications Following Medial Patellar Luxation Corrective Surgery with Tibial Tuberosity Transposition Using a Locking Plate and a Pin Fixation: 45 Unilateral and 20 Single-Session Bilateral Procedures Hawker et al. — The Effect of Locking Head Inserts on the Biomechanical Properties of a 3.5-mm Broad Locking Compression Plate When Used in an Open Fracture-Gap Model 📚 From the July 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the May 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) with two studies that challenge long-held assumptions about orthopedic fixation.  One paper examines whether a novel spacer pin technique can provide the same stability as traditional tibial tuberosity transposition fixation while reducing implant-related complications. The second tackles one of the most debated concepts in fracture fixation: plate working length and whether leaving holes empty near a fracture gap truly provides biomechanical advantages. In this episode: ✅ Sullivan et al. — An ex vivo biomechanical study comparing three fixation methods for tibial tuberosity transposition (TTT) in the treatment of medial patellar luxation. The authors evaluated traditional tension band wiring, dual-pin fixation, and a novel spacer pin technique. All constructs demonstrated comparable stiffness and failure strength, with each tolerating more than 1,000 Newtons of force before failure. Importantly, the spacer pin avoided implant placement directly through the patellar ligament insertion, potentially reducing soft tissue irritation and implant-associated complications while maintaining equivalent biomechanical stability.  ✅ Trefny et al. — A biomechanical investigation of working length in locking compression plate constructs using a distal radius fracture model. Contrary to conventional wisdom, constructs with short working lengths (screws placed adjacent to the fracture gap) were approximately 30% stiffer and generated lower plate strain than constructs with longer working lengths. While long working length constructs initially benefited from load sharing through transcortical contact, the authors highlight the biologic risks associated with repeated bone-end contact, including high interfragmentary strain, bone resorption, and eventual implant fatigue failure.  Together, these studies demonstrate that orthopedic success often comes down to understanding where forces are actually being transmitted—and avoiding assumptions that may no longer hold true. 🎓 Journal Articles Discussed Sullivan et al. — Biomechanical Comparison of Spacer Pin Fixation to Two Established Methods of Tibial Tuberosity Transposition Stabilization in Dogs Trefny et al. — Effect of Plate Screw Configuration on Construct Stiffness and Plate Strain in a Synthetic Short Fragment Small Gap Fracture Model Stabilized with a 12-Hole 3.5-mm Locking Compression Plate 📚 From the May 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the May 2025 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by focusing on a question that underpins every successful orthopedic procedure: how can better planning improve surgical outcomes? From universal deformity correction guides and giant-breed cranial cruciate surgery to rethinking surgical exposure of the canine radius, these studies challenge traditional assumptions and demonstrate how thoughtful planning can improve precision, reduce complications, and simplify orthopedic procedures. In this episode: ✅ Cheon et al. — Evaluated a novel universal distal femoral osteotomy (DFO) guide designed to replace patient-specific 3D-printed cutting guides. Using an adjustable titanium rail-and-pin system, the universal guide achieved correction accuracy within 2 degrees, matching custom 3D-printed guides without requiring CT-based manufacturing or production delays. The findings suggest that a reusable, shelf-ready system can provide the same surgical precision while dramatically simplifying preoperative logistics.  ✅ Guénégo et al. — Reviewed outcomes of AMA-based cranial closing wedge osteotomy (CCWO) in 204 giant-breed dogs (>50 kg) with cranial cruciate ligament disease. By aligning the anatomical and mechanical axes and eliminating excessive shear forces, the procedure achieved grade 4 bone healing in 100% of dogs by eight weeks and an exceptionally low surgical site infection rate of just 0.5%. Double locking plate fixation, postoperative antibiotics, and a 15-day Robert Jones bandage were key components of the protocol.  ✅ Lin et al. — Compared the traditional craniomedial approach (CMA) and the craniolateral approach (CLA) to the canine radius in cadavers. The CLA provided significantly greater exposure (19.4 cm² vs. 13.8 cm²) while avoiding the median neurovascular bundle and allowing simultaneous access to the ulna through the same incision. These findings suggest the CLA may offer substantial advantages for fracture reduction, plating, and minimally invasive fixation techniques.  Together, these studies highlight a simple but powerful principle: better orthopedic outcomes begin long before the first screw is placed. 🎓 Journal Articles Discussed Cheon et al. — Comparing the Accuracy of Patient-Specific Guide and Universal Guide for Distal Femoral Osteotomy in Dogs Guénégo et al. — Modified Cranial Closing Wedge Osteotomy (AMA-Based CCWO) to Treat Cranial Cruciate Ligament Deficient Stifle in 204 Dogs Over 50 Kg: Magnitude of the Craniocaudal Angulation of the Proximal Tibia and Rate of Surgical Site Infection Lin et al. — Does the Craniolateral Approach Provide Better Exposure to the Radius than the Craniomedial Approach for Internal Fracture Fixation in Dogs? 📚 From the May 2025 issue of VCOT 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the May 2026 issue of Veterinary Surgery by examining two studies that reinforce an important surgical lesson: small technical details often determine long-term success. One study challenges the traditional reliance on postoperative immobilization following superficial digital flexor tendon (SDFT) luxation repair, while the other evaluates how radiographic positioning influences preoperative templating for canine total hip arthroplasty. In this episode: ✅ Viskjer et al. — A prospective study evaluating a modified block recession calcaneoplasty for treatment of canine SDFT luxation without routine postoperative tarsal immobilization. All dogs achieved full return to function, with objective gait analysis showing near-normal limb symmetry at long-term follow-up. The study demonstrated that carefully executed sulcus deepening can provide sufficient biomechanical stability without casts or splints, provided adequate calcaneal wall thickness is preserved. The key technical takeaway: maintain approximately 25% of calcaneal width on both the medial and lateral walls to avoid catastrophic fracture and recurrent luxation.  ✅ Zab et al. — A retrospective radiographic study comparing traditional extended hip radiographs with caudocranial flexed hip projections for canine THR templating. The authors found that extended views frequently created a false appearance of a stovepipe femoral canal, underestimating implant size in 88% of cases. Flexed views provided a more realistic representation of femoral canal morphology but tended to slightly overestimate final implant size due to magnification effects. The findings suggest that flexed hip projections may serve as a valuable alternative in dogs with severe osteoarthritis where standard positioning is difficult or impossible.  Together, these studies demonstrate that successful orthopedic outcomes often depend less on adding complexity and more on understanding the underlying biomechanics and anatomy. 🎓 Journal Articles Discussed Viskjer et al. — Surgical management of luxation of the superficial digital flexor muscle tendon (SDFT) using a modified block recession calcaneoplasty without subsequent tarsal joint immobilization Zab et al. — Comparison of canine femoral implant templating for total hip arthroplasty on 25 sets of craniocaudal extended and caudocranial flexed hip radiographs  📚 From the May 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the April 2026 issue of Veterinary Surgery by focusing on two themes that shape every surgeon’s career: building stronger repairs and building stronger surgeons.  From double plate fixation in complex scapular fractures to structured cadaver-based resident training, these papers explore how biomechanics and deliberate practice influence both surgical outcomes and long-term competency. In this episode: ✅ Barrett et al. — An ex vivo biomechanical study evaluating single versus double plating constructs for comminuted canine scapular fractures. Adding a second plate along the caudolateral border nearly halved fracture displacement during cyclic loading (0.81 mm → 0.48 mm) and increased construct stiffness from 392.8 to 563.7 N/mm without increasing strain on the primary implant. The findings suggest that load-sharing double plating may support immediate postoperative weight bearing while potentially reducing reliance on restrictive external coaptation.  ✅ Leu et al. — A prospective pilot study evaluating a three-month cadaveric orthopedic skills curriculum for small animal surgery residents and interns. Using OSATS global rating scores, the study demonstrated significant improvement in technical performance, with median expert scores increasing from 17/35 to 23/35 after training. Interestingly, trainee self-assessment showed poor agreement with expert evaluation, highlighting the importance of objective feedback and structured mentorship during surgical development.  Together, these studies reinforce an important principle in orthopedic surgery: better outcomes depend not only on stronger implants, but also on stronger surgical preparation and training systems. 🎓 Journal Articles Discussed Barrett et al. — Double plate fixation improves stiffness in a comminuted canine scapula fracture gap model compared to single plate fixation Leu et al. — Structured assessment of a cadaveric orthopedic surgical training program of small animal surgeons in training: A prospective observational pilot study 📚 From the April 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our soft tissue coverage from the February 2026 issue of Veterinary Surgery with two studies that highlight how outcomes depend not just on technique, but on tissue biology and surgeon-tool interaction. From large-scale reconstructive flap surgery in cats to laparoscopic instrument design, these papers reveal how both biology and ergonomics can shape surgical success. In this episode, we talk about: ✅ Cinti et al. — A retrospective study evaluating the lateral caudal axial pattern flap for reconstruction of large caudodorsal defects in cats. Despite a 50% complication rate, all complications were minor (seroma, edema, partial dehiscence), and 0% required revision surgery. Surgeons were able to safely use flaps averaging 61.3% of tail length, demonstrating that feline tail vasculature provides robust and reliable perfusion even under high tension, making this a viable option for massive defects.  ✅ Cormillot et al. — A prospective, randomized crossover study of 120 surgeons evaluating laparoscopic instrument handle size. The study found that hand size strongly predicts optimal handle preference, with surgeons wearing glove sizes ≤6.5 significantly preferring smaller handles, while larger-handed surgeons preferred standard sizes. Poor ergonomic fit led to two-handed instrument use, increased wrist strain, and reduced efficiency, highlighting a major but often overlooked contributor to surgeon fatigue and long-term injury risk.  Together, these studies emphasize a critical concept: successful surgery depends on both the biology of the patient and the biomechanics of the surgeon. 🎓 Journal Articles Discussed Cinti et al. — Outcome and complications of lateral caudal axial pattern flap in 14 cats.

In this Simini Small Animal Surgery Podcast episode, we wrap up our soft tissue coverage from the February 2026 issue of Veterinary Surgery with two studies that expand your surgical toolbox using practical, adaptable techniques. From cost-effective lung lobectomy closure methods to biologically driven wound reconstruction, these papers challenge reliance on expensive tools and highlight the power of mechanics and tissue biology working together. In this episode, we talk about: ✅ Cronin et al. — A large clinical series evaluating hilar circumferential ligature techniques for lung lobectomy in dogs and cats. The study reported a low intraoperative hemorrhage rate of 4.3%, with no difference between pre-tied loops and hand-tied knots. However, sliding knots showed a dramatically higher hemorrhage rate (28.6%), reinforcing that knot selection—not just technique—directly impacts safety in thoracic surgery.  ✅ Makar et al. — A retrospective case series describing free autologous omental grafts for large distal limb wounds in dogs. Despite initial graft discoloration and heavy discharge, all wounds healed successfully, shrinking to ~19% of original size by 30 days and achieving full epithelialization in an average of 59 days, with no major complications or long-term lameness. The omentum’s angiogenic and immunologic properties allowed it to revascularize and control infection even in contaminated wounds.  Together, these studies reinforce a key principle: effective surgery doesn’t always require more technology; sometimes, it requires a better understanding of mechanics and biology. 🎓 Journal Articles Discussed Cronin et al. — Perioperative outcomes of 65 dogs and 15 cats undergoing lung lobectomies with a hilar circumferential ligature. Makar et al. — Autologous, free omentum grafts for large, open, distal limb wounds in dogs: Technique and outcome in 10 dogs. 📚 From the February 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our orthopedic coverage from the February 2026 issue of Veterinary Surgery with two studies that challenge how we define stability and success in orthopedic surgery. One paper introduces a simple radiographic marker that may outperform traditional measurements after TPLO. The other tackles a high-stakes clinical dilemma: primary tendon repair versus arthrodesis in Achilles mechanism injuries. In this episode: ✅ Picavet et al. — A retrospective study of 163 dogs evaluating cranial tibial subluxation (CTS) and popliteal sesamoid position before and after TPLO. While only 14.4% of dogs showed preoperative sesamoid displacement, every case returned to normal position postoperatively, making it a reliable and immediate indicator of restored mechanical stability. Importantly, osteotomy position (ideal vs. distal up to 5 mm) did not significantly affect postoperative stability, reinforcing that functional neutralization of cranial thrust—not perfect geometry—is the true goal.  ✅ Wylie et al. — A multi-center retrospective study of Achilles mechanism injuries comparing primary tendon repair with immobilization versus pantarsal arthrodesis. While overall complication rates appeared similar, catastrophic complications occurred in 26.1% of tendon repairs and 0% of arthrodesis cases. Failures were driven not by the tendon repair itself, but by immobilization-related complications such as pin tract infections and cast sores, fundamentally shifting how surgeons should approach treatment planning.  Together, these studies highlight a central surgical principle: true success is measured not just by technique, but by how well we manage the forces—and risks—acting on the repair after we leave the OR. 🎓 Journal Articles Discussed Picavet et al. — Radiographic assessment of popliteal sesamoid position and cranial tibial subluxation in canine stifle joints undergoing TPLO: A retrospective study of 163 dogs Wylie et al. — Complications and outcomes following surgical management of common calcaneal tendon pathology in 80 dogs 📚 From the February 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we kick off our soft tissue coverage from the February 2026 issue of Veterinary Surgery with two studies that highlight how small technical decisions can have major physiologic consequences. From cutaneous perfusion in feline closures to time-saving strategies in GDV surgery, these papers challenge everyday assumptions and offer practical ways to improve outcomes in both routine and emergency procedures. In this episode: ✅ Bayrakdarian et al. — A controlled, within-animal study evaluating continuous intradermal suture patterns in feline skin using laser Doppler imaging. The traditional horizontal mattress pattern decreased perfusion by 24.1%, while a modified pattern with perpendicular bite orientation increased perfusion by over 115% compared to baseline. The findings suggest that suture orientation—not just tension—plays a critical role in preserving microvascular blood flow in cats.  ✅ Chik et al. — A retrospective study of 121 dogs undergoing GDV surgery, comparing barbed suture gastropexy (BSG) to standard incisional gastropexy (SIG). The barbed technique reduced surgical time by ~10 minutes (53.3 vs. 62.6 minutes) without increasing complications, mortality, or recurrence rates. However, 23% of dogs in both groups experienced chronic postoperative GI signs, highlighting that gastropexy prevents rotation—not underlying gastrointestinal disease.  Together, these studies reinforce a key concept: how we close—and how efficiently we operate—directly impacts both immediate and long-term patient outcomes. 🎓 Journal Articles Discussed Bayrakdarian et al. — Comparison of the effect on blood flow of two intradermal suture patterns in feline skin: A within-animal randomized controlled trial Chik et al. — Comparison of short-term outcomes and recurrence rates in dogs undergoing open right-sided barbed suture gastropexy and standard incisional gastropexy for treatment of gastric dilatation-volvulus 📚 From the February 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?

In this Simini Small Animal Surgery Podcast episode, we continue our soft tissue coverage from the January 2026 issue of Veterinary Surgery with two studies examining how surgical technique and airway anatomy influence outcomes in brachycephalic and upper airway disease. From advanced tracheal collapse repair to reassessing common palate surgery assumptions, these papers highlight how surgical decisions can shape long-term respiratory function in dogs. In this episode: ✅ Suematsu et al. — Evaluated long-term outcomes in dogs with severe tracheal collapse treated using continuous extraluminal tracheal prostheses (CETP), including cases with W-shaped tracheal collapse, a less commonly discussed but more severe configuration. Dogs with this morphology were over 12 times more likely to require preoperative oxygen, yet the study reported a 90.9% survival rate at 36 months following surgery, demonstrating that carefully performed extraluminal prosthetic stabilization can provide durable outcomes even in severe cases.  ✅ Timmermans et al. — A prospective study comparing folded flap palatoplasty (FFP) with standard staphylectomy (STS) in brachycephalic dogs using CT measurements three months after surgery. While both techniques improved clinical signs and exercise tolerance, CT analysis revealed that FFP did not consistently reduce soft palate thickness, with some dogs actually showing increased tissue thickness postoperatively. In contrast, traditional staphylectomy resulted in measurable thinning of the soft palate, challenging assumptions about the anatomic advantages of FFP.  Small Animals Vet Surge 2026 Ja… Together, these studies reinforce an important theme: successful airway surgery requires understanding how anatomy, tissue healing, and surgical technique interact over time. 🎓 Journal Articles Discussed Suematsu et al. — Long-term outcomes of dogs with W-shaped or traditional tracheal collapse treated with a continuous extraluminal tracheal prosthesis: A retrospective study Timmermans et al. — Evaluation of soft palate thickness in brachycephalic dogs 3 months after folded flap palatoplasty versus standard staphylectomy 📚 From the January 2026 issue of Veterinary Surgery 🎁 Want to learn more about Simini Protect Lavage or request a sample?
