The purpose of this study was to evaluate hip and pelvis rotations in groups of hemiplegic and diplegic children before and after surgical correction of fixed internal rotation deformity of the hip. Twenty-two children with cerebral palsy (eight diplegia, 14 hemiplegia) having fixed internal rotation deformity at the hip were treated by multilevel surgery which included derotation osteotomy of the femur. Evaluation was done before and at a mean of 3.1 years after surgery using three-dimensional computerized gait analysis. Preoperatively, the patients in the hemiplegia group had a significantly greater compensatory external rotation of the pelvis than those in the diplegic group. Post-operatively there were no significant differences between the two groups. In the hemiplegia group the external rotation of the pelvis was corrected after correction of hip rotation by derotation osteotomy. Patients in the diplegia group showed significant improvements in the hip rotation with no significant change in the pelvis rotation after multilevel surgery.
本研究的目的是评估偏瘫和双瘫儿童在髋部固定内旋畸形手术矫正前后的髋部和骨盆旋转情况。22例患有髋部固定内旋畸形的脑瘫儿童（8例双瘫，14例偏瘫）接受了包括股骨去旋转截骨术在内的多级手术治疗。使用三维计算机步态分析在术前和术后平均3.1年进行评估。术前，偏瘫组患者骨盆的代偿性外旋明显大于双瘫组患者。术后两组之间无显著差异。在偏瘫组中，通过去旋转截骨术矫正髋部旋转后，骨盆的外旋得到了矫正。双瘫组患者在多级手术后髋部旋转有显著改善，而骨盆旋转无显著变化。
