This article reviews 12 cases of humeral lengthening accomplished by transverse midshaft osteotomy and gradual distraction by an external fixator attached to two half pins in the proximal and two half pins in the distal humeral fragments. Six cases were treated by second-stage (application plate, screws, and bone graft with removal of apparatus) and third-stage (removal of plate and screws) procedures. In the other six cases, the external apparatus was allowed to remain in place until the humerus united. There were few complications. There were no nonunions, delayed unions, malunions, or late fractures.
本文回顾了12例通过肱骨干中段横行截骨及使用外固定器进行渐进性牵引延长肱骨的病例。外固定器近端和远端肱骨碎片分别连接两枚半针。6例采用二期（应用钢板、螺钉并植骨，同时拆除外固定器）和三期（拆除钢板和螺钉）手术。另外6例，外固定器一直保留至肱骨愈合。并发症很少。未出现骨不连、延迟愈合、畸形愈合或后期骨折。
