In this paper, we evaluated the long-term results of uncemented total hip arthroplasties using tapered fully porous-coated cobalt-chrome stems (Autophor 900S). The average follow-up was 206 months in 127 hips (113 patients). The articulations of the joints were ceramic-on-polyethylene in 43 hips and ceramic-on-ceramic in 84. The survival rate of the stems at 17 years was 94.5%. A stable stem with bony ingrowth was identified in all 120 hips, excluding femoral revision cases (seven hips). The causes of the seven femoral revisions were aseptic loosening in four, infection in two, and stem fracture in one. No surgical intervention was performed for osteolysis or stress shielding. The Autophor 900S tapered fully porous-coated cobalt-chrome femoral stem revealed encouraging radiographic long-term stability.
在本文中，我们评估了使用锥形全多孔涂层钴铬合金柄（Autophor 900S）的非骨水泥型全髋关节置换术的长期结果。127例髋关节（113例患者）的平均随访时间为206个月。43例髋关节的关节为陶瓷对聚乙烯，84例为陶瓷对陶瓷。柄在17年时的生存率为94.5%。在排除股骨翻修病例（7例髋关节）后的所有120例髋关节中均发现了具有骨长入的稳定柄。7例股骨翻修的原因是4例无菌性松动、2例感染和1例柄骨折。未对骨溶解或应力遮挡进行手术干预。Autophor 900S锥形全多孔涂层钴铬合金股骨干显示出令人鼓舞的影像学长期稳定性。
