We present a case of humeral lengthening for a limb length discrepancy of 7.7 cm due to proximal humeral growth arrest in a 12-year-old boy. Lengthening of 69 mm was achieved using the Wagner technique. Bone grafting was not required. Humeral lengthening may be performed for upper extremity limb length discrepancy with good results. Objectives of treatment must include protection of the radial nerve from traction injury and from entrapment in the osteotomy site. Elbow extension may be lost during lengthening, but in the adolescent age group, full return of elbow motion can be expected.
我们报告了一例12岁男孩因肱骨近端生长停滞导致肢体长度相差7.7 cm而进行肱骨延长术的病例。采用瓦格纳技术实现了69 mm的延长。无需进行骨移植。肱骨延长术可用于治疗上肢肢体长度差异，效果良好。治疗目标必须包括保护桡神经免受牵拉损伤以及避免其陷入截骨部位。延长过程中可能会出现肘关节伸展功能丧失，但在青少年年龄组中，预计肘关节运动功能可完全恢复。
