The aim of this study is to evaluate the complications of humeral lengthening and their associated factors. Fifty-four achondroplastic patients were treated by bilateral humeral lengthening. Our original shoulder sling was sufficient to prevent shoulder dislocation. Pre-existing radial head dislocation was observed in 18 patients. Lengthening was accomplished in all cases without a decrease in the elbow function. Seven humeri fractured after the fixator removal. The risk factors for postoperative fracture were a waiting period of less than 5 days, a healing index less than 25, and the concave shape of the callus. There was no radial nerve palsy.
本研究的目的是评估肱骨延长术的并发症及其相关因素。54例软骨发育不全患者接受了双侧肱骨延长术治疗。我们最初的肩吊带足以防止肩关节脱位。18例患者术前存在桡骨头脱位。所有病例均完成延长，且肘关节功能未下降。7例肱骨在固定器拆除后发生骨折。术后骨折的危险因素为等待期少于5天、愈合指数小于25以及骨痂呈凹形。未发生桡神经麻痹。
