Seventy-eight patients who had undergone bilateral derotational osteotomy of the femur for medial femoral torsion were reviewed to evaluate the procedure and to determine the frequency of postoperative complications. Patients averaged 6 years of age at the time of the procedure; girls predominated. Before derotational osteotomy, the mean hip rotation measurements were 84 degrees medially and 16 degrees laterally; following the procedure, mean hip rotations were 41 degrees medially and 51 degrees laterally. Medial femoral torsion was reduced from 54 degrees mean to 14 degrees. Balancing these favorable results, however, was a 15% risk of complications; 12 of our patients had problems associated with loss of fixation, errors in amount of correction, fractures, heel ulcer, or infection. Derotational osteotomy is only justified for the child with a persistent severe disability from medial femoral torsion. The parents should be aware of the significant risks and the lack of evidence for any long-term adverse effects if moderate MFT is left uncorrected.
对78例行双侧股骨去旋转截骨术治疗股骨内旋的患者进行了回顾性研究，以评估该手术并确定术后并发症的发生率。患者手术时平均年龄为6岁，女性居多。去旋转截骨术前，髋关节平均内旋角度为84度，外旋角度为16度；手术后，髋关节平均内旋角度为41度，外旋角度为51度。股骨内旋从平均54度降至14度。然而，权衡这些良好结果的是，有15%的并发症风险；我们的12例患者出现了与固定丢失、矫正量错误、骨折、足跟溃疡或感染相关的问题。去旋转截骨术仅适用于因股骨内旋而持续严重残疾的儿童。家长应意识到，如果中度股骨内旋未得到矫正，存在重大风险且缺乏任何长期不良影响的证据。
