Non-traumatic osteonecrosis involving the femoral head frequently occurs in young patients especially due to steroids administration or other some reasons. In cases of extensive lesion of the weight-bearing area, collapse is usually progressive. Preservation of the joint in young patients to avoid joint replacement procedures is important and widely accepted. Transtrochanteric rotational osteotomy for the femoral head osteonecrosis is ideal procedure moving the remained viable femoral head area to the loaded portion below the acetabular roof, thus hip joints can be preserved for long term by remodeling even if the stage is progressed preoperatively. This procedure is technically difficult, but should be common in orthopaedic surgeons.
非创伤性股骨头坏死常见于年轻患者，尤其是因使用类固醇或其他一些原因所致。在负重区广泛病变的情况下，塌陷通常呈进行性。对于年轻患者而言，保留关节以避免关节置换手术非常重要，且已被广泛认可。对于股骨头坏死，经转子旋转截骨术是一种理想的手术方法，可将剩余的股骨头存活区域转移至髋臼顶下方的负重部位，这样即使术前病情已进展，髋关节仍可通过重塑得以长期保留。该手术技术难度较大，但在骨科医生中应较为常见。
