title: Surgical resolution of an avulsion fracture of the peroneus tertius origin in a giraffe (Giraffa camelopardalis reticulata).
abstract: A 4-mo-old, 185-kg male giraffe (Giraffa camelopardalis reticulata) was presented due to stifle effusion and lameness of 3-wk duration. Radiographs revealed a fracture of the extensor fossa of the lateral trochlear ridge of the femur at the origin of the peroneus tertius. Under anesthesia, dysfunction of the reciprocal apparatus was documented by flexing the stifle while the tarsus remained extended. An avulsion fracture of the origin of the peroneus tertius and extensor digitorum longus muscle was diagnosed. An exploratory arthroscopy of the femorotibial joint was followed by arthrotomy to excise the large bone fragment from its soft tissue attachments. Because of the fractious temperament of the animal, postoperative care was restricted to stall rest for 3 mo, and no postoperative complications arose. Only a mild residual lameness remained by 6 mo after surgery.
