摘要
目的 观察分析臀肌挛缩症致骨盆倾斜的病因及治疗效果。方法 对 84例臀肌挛缩症合并骨盆倾斜患者术前行骨盆倾斜方向检查，术中对臀中肌和臀小肌进行探查并将挛缩的臀肌完全松解。结果 84例臀肌挛缩症合并骨盆倾斜患者，假性长肢侧臀小肌挛缩者 76例，占 90％。随访 68例，平均 2.6年， 63例完全矫正，其中 61例一次手术矫正， 2例再次矫正； 3例部分矫正；余 2例因臀肌外展肌肌力减弱致术后步态轻度不稳。结论 臀中肌与臀小肌挛缩是导致骨盆倾斜的重要原因，尤以臀小肌挛缩发生率高，且位置隐蔽。术前骨盆倾斜方向检查，有助于制定手术方案，选择切口，使挛缩的臀肌完全松解。
Objective To analyze the cause and treatment effect of pelvis obliquity accompanied with the gluteal muscle contracture. Methods 84 cases of gluteal muscle contracture with pelvis obliquity and their pelvis obliquity direction were examined. During surgery it was emphasized that release of the glutaeus minimus and glutaeus medius muscle contracture must be complete in order to expect correction of pelvis obliquity. Results Among the 84 cases of gluteal contracture with the pelvis obliquity, 76(90％ ) cases had gluteal muscle contracture of the longer limp. Follow-up had been done in 68 cases for 2.6 years. The pelvis obliquity disappeared completely in 63 of the 68 cases. Among the 63 cases, 61 cases underwent operation once while 2 cases needed revision operation. 3 of 68 cases were corrected partly. The other two cases had unstability in steps as a result of poor function of the gluteal abductors. Conclusion The main cause of the pelvis obliquity is contracture of the glutaeus minimus and medius muscles. The glutaeus minimus muscle contracture is an important factor that cause the pelvis obliquity in gluteal muscle contracture and should be released completely by surgery.
