An intertrochanteric femoral osteotomy is carried out to correct intoeing gait and to improve hip centration in patients with spastic cerebral palsy. The long-term effect of such osteotomies on the neck-shaft angle (NSA) and anteversion angle (ATA), as well as on hip-joint centration, was evaluated in 63 hips of 45 patients with observation times of 11-18 years (mean, 15.4). The postoperative loss of correction of the NSA and ATA was the more pronounced the younger the patients were at the time of intervention. This was particularly true when the hip joint was subluxated or dislocated and when the operation was done before the age of 4 years. Patients of this age group lost 96% of the correction of the NSA and 42% of the ATA. Hip centration always improved, but corrective femoral osteotomy alone did not result in a sufficient coverage in cases of subluxation and dislocation in the short and long term.
进行股骨粗隆间截骨术以纠正内旋步态并改善痉挛性脑瘫患者的髋关节中心定位。在45例患者的63个髋关节中评估了此类截骨术对颈干角（NSA）和前倾角（ATA）以及髋关节中心定位的长期影响，观察时间为11至18年（平均15.4年）。干预时患者年龄越小，NSA和ATA术后的矫正丢失越明显。当髋关节半脱位或脱位时以及手术在4岁之前进行时尤其如此。这个年龄组的患者失去了96%的NSA矫正和42%的ATA矫正。髋关节中心定位总是得到改善，但单纯的股骨截骨术在短期和长期内对于半脱位和脱位病例并不能提供足够的覆盖。
