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.
一只黄颈亚马逊鹦鹉(Amazona ochrocephala auropalliata)在左胫跗骨遭受创伤性骨折5个月后前来就诊。最初,对简单、闭合的骨干中段骨折采用髓内针固定,并使用改良的罗伯特-琼斯绷带进行外部固定。在随后的5个月里,骨骼出现骨质减少,胫跗骨中段出现可能的缺血性坏死。在各种固定尝试失败后,为这只鹦鹉安装了环形固定器装置,并尝试进行骨搬运骨生成术。在7周内,左胫跗骨重新生长至全长,但近端骨折线处的对接部位未愈合。在进行了另外两次清创骨端以促进愈合的手术后,这只鹦鹉的腿恢复了功能。这是首次报道骨搬运骨生成术在宠物鸟临床中的应用。材料和技术成功应用于这只鹦鹉,这表明骨搬运骨生成术在鸟类大骨缺损修复方面值得进一步研究。
