Bone transport osteogenesis for reconstruction of a bone defect in the tibiotarsus of a yellow-naped Amazon parrot (Amazona ochrocephala auropalliata).
A yellow-naped Amazon parrot (Amazona ochrocephala auropalliata) was presented 5 months after a traumatic fracture of its left tibiotarsus. Fixation of the simple, closed, mid-diaphyseal fracture was originally with an intramedullary pin and external coaptation with a modified Robert-Jones bandage. During the subsequent 5 months, the bone became osteopenic, and the middle third of the tibiotarsus exhibited probable avascular necrosis. After various fixation attempts failed, the parrot was fitted with a ring fixator device, and bone transport osteogenesis was attempted. Within 7 weeks, the left tibiotarsus had regrown to full length, but the docking site at the proximal fracture line had not healed. After 2 more surgeries to debride bone ends to stimulate healing, the leg in this parrot became functional. This is the first reported clinical use of bone transport osteogenesis in a pet bird. Materials and techniques were applied successfully to this parrot, which suggests that bone transport osteogenesis deserves further study for the repair of large bone defects in birds.
