Hip muscle imbalance in cerebral palsy may cause subluxation or dislocation. Pelvic radiographs were used to assess hip stability in 40 affected hips before and after open adductor surgery. Preoperative rates of hip migration were determined from radiographs using the center-edge angle and migration percentage. Either an open adductor tenotomy with partial obturator neurectomy or a posterior adductor transfer was performed. Follow-up averaged 5 years, with a reversal of preoperative lateral hip migration in 36 of 40 hips. There was no statistically significant difference in the radiographic outcome of the two procedures. Lateral hip migration can be arrested or reversed with properly timed hip adductor surgery.
脑瘫患者的髋部肌肉失衡可能导致半脱位或脱位。在开放性内收肌手术前后，使用骨盆X线片评估40例患髋的髋关节稳定性。术前通过X线片利用中心边缘角和移位百分比确定髋关节移位率。实施开放性内收肌切断术并部分切除闭孔神经或进行内收肌后移术。随访平均5年，40例患髋中有36例术前髋关节外侧移位得到纠正。两种手术的影像学结果无统计学显著差异。适时进行髋部内收肌手术可阻止或纠正髋关节外侧移位。
