股骨头坏死，早期的、年轻的患者应尽快接受保髋手术治疗，因为越早做效果相对越好。对于早期保髋治疗失败的，或者一发现就已经到了股骨头坏死的中晚期，股骨头塌陷，保髋治疗效果预期不理想的患者，就面临着人工关节置换手术的选择。
人工髋关节置换手术是指通过手术将髋关节病变的组成部分去除植入新的人工组件（根据髋关节的组成分为髋臼假体和股骨假体，其材料有金属、高分子聚乙烯、陶瓷等）。其目的在于其目的是切除病灶，解除髋关节疼痛，恢复关节的活动与原有的功能。

Conservativetreatments for aseptic osteonecrosis of the femoral head have their ancestor inthe core decompression of the femoral neck， recommended by Ficat. Due toinconsistent results， this treatment has been optimized by either vascularizedfibular grafting， or by injecting autologous stem cells into the necrotic zone.The French promoters have published long-term results， showing efficacy in theearly stages of the disease， where the femoral head has not yet lost itssphericity. Over the last 10years， comparative studies， sometimes randomized，opposing them to simple core decompression， have been published bynon-promoters， confirming the possibility of stabilization or even regressionof necrosis area. But these techniques are not easy to implement. Cell therapyrequires treatment of marrow samples by centrifugation to obtain a pellet witha high concentration of haematopoietic cells. The now proven long-term efficacyas well as the safety of this technique make it the method of choice fortreating young patients detected at the sub-radiological stage by MRI.Unfortunately， many are seen late with detached cephalic cartilage or collapsedfemoral head and have no other option than total hip arthroplasty. Thistechnique is very reliable. With alumina ceramics， results of more than 20yearsshow the absence of wear and osteolysis， although other complications such asinstability or periprosthetic fractures may occur in these young and activepatients.
