In view of the high rate of loosening of conventional cemented hip prostheses, cementless implants are gaining popularity in Europe and North America. Smooth-surfaced "press fit" prostheses are designed for autolocking in the femoral canal at the time of installation. Fifteen patients were prospectively followed by bone imaging with Tc-99m MDP at three-month intervals after cementless "press fit" hip arthroplasty to define the "normal" distribution of mechanical stress to the surrounding bone, as well as the incorporation of bone allografts used for reconstruction of resorption sites in cases of revision surgery.
鉴于传统骨水泥型髋关节假体的松动率较高，非骨水泥型植入物在欧洲和北美越来越受欢迎。表面光滑的“压配”假体设计用于在安装时自动锁定在股骨髓腔内。对15例患者在进行非骨水泥型“压配”髋关节置换术后每隔三个月进行一次锝-99m亚甲基二膦酸盐骨显像，以确定机械应力在周围骨骼中的“正常”分布，以及在翻修手术中用于重建吸收部位的同种异体骨的骨结合情况。
