Femoral shortening is a well proven method of correcting a leg length discrepancy once growth has ceased. The discrepancy should be significant enough to justify the procedure, and should be ideally confined to the femurs. The musculature of the femur to be shortened should be normal. A segment of femur equal to the discrepancy is excised at either the midshaft, subtrochanteric, or supracondylar levels. Secure internal fixation of the osteotomy is essential. Equalization of the femurs (femoral shortening combined with femoral lengthening of the opposite leg) can be performed for femoral discrepancies of over 8 cm.
一旦生长停止，股骨缩短术是一种经充分证实的矫正腿长差异的方法。这种差异应足够显著，足以证明该手术的合理性，并且理想情况下应仅限于股骨。拟缩短的股骨的肌肉组织应正常。在股骨干中段、转子下或髁上水平切除一段与差异长度相等的股骨。截骨处进行可靠的内固定至关重要。对于超过8厘米的股骨长度差异，可以进行股骨均衡术（股骨缩短术联合对侧股骨延长术）。
