CASE HISTORY: A 15-year-old female huacaya @entity7858 ( @entity7858 ) was referred because of a non-weight-bearing @entity1273 (4/4) in the left pelvic limb caused by a grade three open @entity174 . The referring veterinarian treated the @entity174 with conservative management using bandages, but it progressively evolved to a non-union. CLINICAL FINDINGS AND DIAGNOSIS: Clinical examinations revealed external wounds on the medial and lateral surfaces of the metatarsus. Radiographs confirmed an open, nonarticular, displaced, diaphyseal @entity174 of the left metatarsus. TREATMENT AND OUTCOME: Cancellous bone was sourced from @entity291 proximal and distal femur epiphyses, followed by a thermal shock procedure to achieve decellularisation, to produce a xenograft. Open reduction and internal fixation of the @entity174 using locking plates was performed. Alignment of the @entity174 fragments was corrected and the xenograft was placed at the debrided @entity174 site to stimulate and harness osteogenesis in situ. Clinical and radiographic follow-up was performed up to 40 weeks postoperatively. Clinical evaluations revealed that the @entity7858 gradually increased weight bearing following bandage removal 10 days after surgery. Serial radiographs showed correct alignment of the left metatarsus, progressive bone modelling and, complete bone union at 12 weeks. Ten months postoperatively the @entity7858 showed no signs of @entity1273 and resumed normal activity. CLINICAL RELEVANCE: For management of a metatarsal non-union, a combination of @entity291 xenograft application and angular stable internal fixation progressed toward an excellent long-term recovery.
