This study evaluates our early experience with unilateral humeral lengthening in children and adolescents. From 1995 till 2001, 16 cases with unilateral humeral shortening ranging from 5.5 to 15 cm were referred to our center. The cause was Erb's palsy in eight cases, epiphyseal injury in five cases and infection in three cases. The average age at operation was 13 years (range 8.5-17 years). Hybrid fixation using wires and half pins were applied to all cases to minimize the risk of operative neurovascular complications. Osteotomy was performed in the middle third of the humerus through a posterior approach. After a latent period of 5-7 days lengthening started at a rate of 0.33 mm every 8 h. At an average follow up of 3 years and 2 months (range 1 year and 4 months to 5 years and 6 months) there were 10 excellent and six good results. The average healing index was 28 days/cm. Complications included pin tract infection in all cases; radial nerve palsy in one patient whose humerus overlengthened by 2 cm but improved completely after compression; fracture of the regenerate in two cases.
本研究评估了我们在儿童和青少年单侧肱骨延长方面的早期经验。1995年至2001年期间，16例单侧肱骨短缩5.5至15厘米的患者被转诊至我们中心。病因包括8例臂丛神经麻痹、5例骨骺损伤和3例感染。手术平均年龄为13岁（范围8.5至17岁）。所有病例均采用钢丝和半针混合固定，以尽量降低手术中神经血管并发症的风险。通过后路在肱骨中三分之一处进行截骨术。经过5至7天的潜伏期后，开始以每8小时0.33毫米的速度延长。平均随访3年2个月（范围1年4个月至5年6个月），结果为10例优，6例良。平均愈合指数为28天/厘米。并发症包括所有病例均有针道感染；1例患者出现桡神经麻痹，其肱骨过度延长2厘米，但压迫后完全恢复；2例出现再生骨骨折。
