VCOT March 2025 – Ortho Part 1: THA Cup Design, DPO Coverage & SOP Bending Myths

In this Simini Small Animal Surgery Podcast episode, we wrap up orthopedic highlights from the March 2025 issue of VCOT, focusing on implant design, joint coverage, and surgical habits that don’t always hold up under pressure. From hips to plates, this episode delivers biomechanical insights you can apply immediately in the OR.We cover:✅ Huels et al. — A clinical follow-up of 30 canine total hip arthroplasties using a second-generation selective laser melted screw cup (SCSL). The implant showed a cup complication rate of just 3.3%, and no late aseptic loosening at a 17.5-month median follow-up. Most failures occurred on the femoral side, indicating the new porous trabecular cup design may finally solve long-term cup fixation✅ Lomas et al. — A CT-based study showing that double pelvic osteotomy (DPO) improved mean dorsal lateral subluxation (DLS) scores from 36.1% to 71.4%—effectively shifting dysplastic hips from high-risk to low-risk OA territory. The biggest correction came with 30° plates, reinforcing the value of pre-op CT templating to optimize surgical planning✅ Lu et al. — A mechanical study testing whether leaving bending tees in empty SOP nodes improves strength. While medial-lateral bending stiffness increased by a statistically significant 2.08 N/mm, the authors concluded the clinical benefit was negligible. Leaving tees in is a habit, not a proven technique, and doesn’t meaningfully increase construct stiffness🎓 Journal Articles Discussed:Huels et al. —Complications and Long-Term Outcome in 30 Canine Total Hip Arthroplasties Using a Second-Generation Selective Laser Melted Screw CupLomas et al. — The Impact of Double Pelvic Osteotomy on Dorsolateral Subluxation in 24 DogsLu et al. — Comparison of Bending Stiffness between String of Pearls Plate-Bone Substitute Constructs with and without Bending Tees in a Fracture Gap Model🎁 Want to learn more about Simini Protect Lavage or request a sample?Learn More: www.simini.comRequest a Sample:https://www.simini.com/evaluation-kit
