儿童臀小肌挛缩致肢体假性不等长的手术治疗

Surgical Treatment of Gluteus Minimus Contracture

目的 :探讨臀小肌挛缩导致骨盆倾斜合并肢体假性不等长的原因 ,以及手术治疗方法改进后的效果。方法 :本组 3 2例骨盆倾斜合并肢体假性不等长的患儿采用臀小肌松解延长手术 ,术后配合练习臀肌挛缩操和摆臀锻炼。结果 :术后经过 6个月以上的随访 ,骨盆倾斜合并肢体假性不等长已完全矫正 ,步态恢复正常。结论 :臀中、小肌都可以导致骨盆倾斜合并肢体假性不等长 ,但是臀小肌的作用更甚于臀中肌。针对臀小肌挛缩的松解延长术是解决骨盆倾斜合并肢体假性不等长的重要治疗方法 ,应引起重视。

Objective:To study the cases of gluteaus minimus contracture with obliquity of pelvis and false unequal leg length,report the experience of the improved surgical treatment method.Methods:Cut the contracture tract and extended the tendon to 32 cases of gluteus minimus with obliquity of pelvis and false unequal leg length,after surgery trained gluteal muscle contracture drill and pendular movement pelvis exercise.Results:After operation follow-up period over six months,all patients were normal.Conclusion:The contracture of middle and minimus gluteus were able obliquity of pelvis and false unequal leg length.It is more hard of obliquity of pelvis about glueaus minimus contracture than about gluteaus middle contracture.The release lengthening operation of glueaus minimus contracture is important treatment method of obliquity of pelvis and false unequal leg length.
