Study tests SDFT luxation repair without tarsal immobilization

A prospective observational study in Veterinary Surgery reports that a modified block recession calcaneoplasty may offer a way to treat superficial digital flexor tendon luxation in dogs without postoperative tarsal joint immobilization. The study included 11 surgeries in nine client-owned dogs with SDFT luxation and no concurrent disease, and found significant improvement in limb symmetry and function at 12 months after surgery. That’s notable because postoperative immobilization has commonly been part of management for this uncommon orthopedic injury, even as newer reports have started to question whether every case needs it.

Why it matters: For veterinary surgeons and rehab teams, the paper adds prospective clinical data to a small but growing body of literature suggesting that calcaneal groove-modifying techniques may reduce reluxation risk while potentially avoiding the downsides of prolonged external coaptation or joint immobilization. Earlier reports have described successful repair strategies with splints, temporary restraining pins, or calcaneoplasty variants, but evidence has largely been limited to case reports and retrospective series.

What to watch: Whether larger comparative studies confirm which dogs can safely forgo immobilization, and how this technique performs against more traditional repair-and-coaptation protocols. (pmc.ncbi.nlm.nih.gov)
