Twenty skeletally mature patients (average age, sixteen years and seven months; range, thirteen years and seven months to twenty-two years and four months) were treated for limb-length inequality by closed shortening of the femur. Preoperatively, the amount of femoral shortening that was necessary to level the pelvis was determined radiographically by balancing the pelvis with calibrated lifts under the shorter extremity. All twenty shortening procedures were performed with an intramedullary cam saw and insertion of an intramedullary rod through a gluteal incision; no additional incisions were needed to complete the procedure. At the most recent follow-up, the limb-length discrepancy was one centimeter or less in all twenty patients. All patients reported that the limbs seemed to be of equal length and that the pelvis felt level.
二十名骨骼成熟的患者（平均年龄为十六岁零七个月；范围为十三岁零七个月至二十二岁零四个月）接受了通过股骨闭合缩短术治疗肢体长度不等的手术。术前，通过在较短下肢下方使用校准过的垫片平衡骨盆，以X线片确定使骨盆水平所需的股骨缩短量。所有二十例缩短手术均使用髓内凸轮锯进行，并通过臀部切口插入髓内棒；无需额外切口即可完成手术。在最近的随访中，所有二十例患者的肢体长度差异均在一厘米或以内。所有患者均表示，双下肢看起来长度相等，且骨盆感觉处于水平状态。
