目的探索重度臀肌筋膜挛缩症及其所致臀腰部畸形的最佳治疗方法。方法对25例重度臀肌筋膜挛缩症及其所致臀腰部畸形患者，依Z成形术原则进行挛缩带和挛缩瘢痕的松解后，将局部皮肤进行重新分配和塑形加以治疗。结果25例双侧髋关节功能完全恢复，步态正常，腰臀部形态基本平整，无坐骨神经损伤。术后随访6个月至3年，平均1．6年，无畸形复发。结论Z成形术既解除了挛缩带对关节功能的牵制，又可对局部皮肤进行重新分配，矫正挛缩造成的凹陷畸形，术后功能和外形效果均佳，是治疗重度臀肌筋膜症及其所致臀腰部畸形的良好方法。

Treatment of deformities secondary to gluteal muscles and fascia contracture with Z-plasty

Objective To describe an appreciate operation method in the treatment of deformi-ties secondary to gluteal muscles and fascia contracture. Methods 25 cases of serious secondary de-formity of gluteal muscles and fascia contracture were treated by Z-plasty. The contracted fascia and scar were loosed and the skin around the wound was rearranged. Results The following-up time was from 6 months to 3 years with an average time of 1.6 years. All cases rehabilitated to normal or nearly normal in gait. Aesthetic results were also satisfactory. No recurrence was observed.
