R.P., a fifty-seven-year-old man, underwent a total hip replacement with a newly designed, cementless hip system. Within the first several months after surgery, he had persistent thigh pain. Radiographs made at one year indicated progressive radiolucent lines surrounding the femoral component. He required revision surgery for aseptic loosening of the femoral component. Several months following the revision, a single journal article indicating a similar problem at another institution with the same device was published. A year later, two additional articles appeared in the literature. One year later, the femoral device originally implanted in R.P. was removed from the market.
R.P.，一位 57 岁男性，接受了全新设计的无水泥髋关节置换系统的全髋关节置换术。手术后的头几个月，他一直有大腿疼痛。一年时的 X 光片显示股骨部件周围有进行性透亮线。他因股骨部件无菌性松动需要进行翻修手术。翻修手术后几个月，另一机构使用相同器械出现类似问题的单一期刊文章发表。一年后，文献中又出现了两篇文章。一年后，最初植入 R.P. 的股骨器械被撤出市场。
