Surgical treatment for the correction of upper limb discrepancies with primary involvement of the humerus is reported. The operative technique, the lengthening procedure with the G3-IOR distractor, and the successive external fixation are described. In the seven extremities treated, the mean lengthening was 5.0 cm, the mean percentage lengthening was 25.2%, and the mean residual discrepancy was 2.9 cm. The authors believe that humeral lengthening is advisable for 13- to 15-year-old patients with hypoplasia of the humerus when the discrepancy is greater than 3 cm.
本文报道了针对主要累及肱骨的上肢长度差异进行矫正的手术治疗。文中描述了手术技术、使用G3-IOR撑开器的延长过程以及后续的外固定。在接受治疗的7例肢体中，平均延长长度为5.0厘米，平均延长百分比为25.2%，平均残余差异为2.9厘米。作者认为，对于肱骨发育不全、年龄在13至15岁且长度差异大于3厘米的患者，肱骨延长术是可取的。
