【摘要】 目的 通过手术矫正小儿肱骨内翻及短缩畸形以改善患儿上肢不等长和肩关节外展功能受限。方法 本组5例, 10~17岁患儿采用一次多平面肱骨截骨, 即在肱骨不同平面交叉穿过几组克氏针与预组装好的伊氏外固定器相连接, 在肱骨外科颈下做外翻截骨后, 使上端Ω环于矢状面向外下翻转纠正肱骨头干角。 另取切口做肱骨中下1/3骨皮质切开术。 术后5~7d开始骨延长。结果 经随访, 本组患儿平均肱骨延长8cm。 肱骨上端外翻截骨和肱骨中下1/3延长部骨愈合良好, 肩关节外展改善20°~40°。 无术中血管神经损伤及骨延长引起的各种并发症。结论 采用本法能有效治疗小儿肱骨内翻及短缩畸形。

【Abstract】 Objective To evaluate the application of Ilizarov technique in correction of humerus varus.Methods From 1990 to 1998, 5 patients aged from 10 to 17 years, underwent two-level osteotomy. Kirschner wires were inserted and attached to the Ilizarov external fixator. After valgus osteotomy of the proximal humerus, the upper ring of the external fixator was rotated downwards and outwards to correct the neck/shaft angulation. Second corticotomy of one third lower humerus was performed to lengthen the shaft.Results The follow-up results showed that a mean humeral lengthening of 8 cm was achieved with good union at the osteostomy sites. The glenohumeral abduction improved by 20-40 degrees. No neurovascular complication was encountered.Conclusion Humerus varus in children can be effectively managed using Ilizarov technique.
