Hybrid metal-on-metal surface arthroplasty of the hip has recently been introduced, with a vast number of implants used in European countries including Belgium. This article presents results in 252 hips with a mean follow-up of 2.8 years. Using a tight press-fit with minimal cement mantle as the technique of femoral fixation, there have been only three failures. The main complications have been avascular necrosis of the femoral head and femoral neck fracture. In most cases, patients returned to a high functional level with no restrictions in their physical activity and were highly satisfied. Future refinements in surgical technique and instruments will make this procedure more accessible and reproducible for the surgeon.
髋关节混合金属对金属表面置换术最近被引入，在包括比利时在内的欧洲国家有大量植入物被使用。本文介绍了252例髋关节置换的结果，平均随访2.8年。采用紧密压配且股骨固定时骨水泥套最小化的技术，仅出现了3例失败病例。主要并发症为股骨头缺血性坏死和股骨颈骨折。在大多数情况下，患者恢复到较高的功能水平，身体活动不受限制，满意度很高。未来手术技术和器械的改进将使该手术对外科医生来说更容易实施且更具可重复性。
