The aspherical coxa magna femoral head can be made more spherical by intra-articular osteotomy. The Ganz technique of femoral head reduction osteotomy to reduce the size and restore the spherical shape of the femoral head has been performed in 20 patients over the past 5 years. A good or excellent functional and radiographic result was obtained in 14 of the 20. A fair result (decreased pain but no improvement in range of motion) occurred in 3, and a poor result (stiffness and pain) occurred in 3. The preliminary results of this technique are therefore very promising.
通过关节内截骨术可使非球面性的大髋臼股骨头变得更接近球形。在过去5年中，对20例患者实施了甘茨股骨头复位截骨术，以减小股骨头尺寸并恢复其球形形状。20例患者中有14例获得了良好或优秀的功能和影像学结果。3例结果尚可（疼痛减轻但活动范围无改善），3例结果较差（僵硬和疼痛）。因此，这项技术的初步结果非常有前景。
