Metal-on-metal hip resurfacing arthroplasty has undergone a recent resurgence as an alternative treatment option for young and active patients,since it preserves bone stock for subsequent revision procedures and restores anatomic hip mechanics. At the same time, some complications such as femoral neck fracture,prosthesis loosening,especially the high levels of cobalt-chromium metal ions in blood and urine from the elevated levels of metal ions could have a negative impact on the body. Here is to make a review on the complications commonly associated with metal-on-metal hip resurfacing arthroplasty and the influence on the body.%金属髋关节表面置换术通过保留股骨近端骨量从而恢复髋关节正常的生物力学特性及关节的稳定性,为年轻及活动量大的患者提供了一个良好的治疗方案.与此同时,这一手术方案存在其特有的并发症,如股骨颈骨折、假体松动,特别是假体置换术后产生大量的金属离子使机体内血液尿液中金属离子水平升高,从而可能对机体产生不利影响.现就金属对金属全髋假体置换术后出现的特有并发症及其对机体的影响进行综述.
