A 9-month-old infant girl with Down syndrome presented with an atrophic nonunion of the right humerus diaphysis secondary to birth trauma. Surgical intervention included open reduction and external fixation plus cadaveric cancellous bone allograft and platelet-rich plasma and then was changed to an external fixator in axial compression. At 16 months after surgery, bone healing was achieved.
Nonunions in infants are rare, and their treatment is a challenge; an adequate vascular supply with good stabilization and reduction are keys to management. We believe that the improvement in reduction and stability under axial compression were the keys to achieve consolidation.
一名 9 个月大的唐氏综合征女婴因出生创伤导致右肱骨骨干萎缩性骨不连。手术干预包括切开复位和外固定加同种异体松质骨移植物和富血小板血浆，然后改为轴向压缩外固定器。术后 16 个月，骨折愈合。
婴儿的骨不连很少见，其治疗是一个挑战；充足的血管供应、良好的稳定性和复位是治疗的关键。我们认为，轴向压缩下复位和稳定性的改善是实现愈合的关键。
