Veterinary Surgery May 2026 – Ortho Part 2: SDFT Luxation Without Casts & Smarter THR Templating

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 DiscussedViskjer et al. — Surgical management of luxation of the superficial digital flexor muscle tendon (SDFT) using a modified block recession calcaneoplasty without subsequent tarsal joint immobilizationZab 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?Learn More: www.simini.comRequest a Sample:https://www.simini.com/evaluation-kit
