A modified innominate osteotomy was employed to treat postural imbalance by a hemipelvic lengthening in twenty patients, five to twenty years old. Diagnoses associated with the postural imbalance included acetabular dysplasia with ipsilateral femoral shortening, pure limb-length inequality, primary intrapelvic asymmetry, and decompensated scoliosis. The functionally low hemipelvis was lengthened as much as three centimeters by distraction at the osteotomy and insertion of a quadrangular bone graft. The option of a variable amount of acetabular redirection was especially useful in patients with ipsilateral acetabular dysplasia. Review of the patients after two to six years revealed that an average lengthening of 2.3 centimeters had been achieved. Fourteen patients had a balanced stance without a lift postoperatively, and the size of the lift required in the other six patients was greatly reduced.
采用改良的无名骨截骨术，通过半骨盆延长治疗20例5至20岁因姿势性失衡的患者。与姿势性失衡相关的诊断包括髋臼发育不良伴同侧股骨缩短、单纯肢体长度不等、原发性骨盆内不对称以及失代偿性脊柱侧弯。通过截骨处撑开并植入四边形骨块，将功能较低的半骨盆延长多达3厘米。对于同侧髋臼发育不良的患者，髋臼不同程度重定向的选择尤为有用。对患者进行2至6年的随访发现，平均延长了2.3厘米。14例患者术后站立姿势平衡，无需垫起，其他6例患者所需垫起的高度也大幅降低。
