We have evaluated the in vivo migration patterns of 164 primary consecutive Charnley-Kerboull total hip replacements which were undertaken in 155 patients. The femoral preparation included removal of diaphyseal cancellous bone to obtain primary rotational stability of the stem before line-to-line cementing. We used the Ein Bild Roentgen Analyse femoral component method to assess the subsidence of the femoral component. At a mean of 17.3 years (15.1 to 18.3) 73 patients were still alive and had not been revised, eight had been revised, 66 had died and eight had been lost to follow-up. The mean subsidence of the entire series was 0.63 mm (0.0 to 1.94). When using a 1.5 mm threshold, only four stems were considered to have subsided. Our study showed that, in most cases, a highly polished double-tapered stem cemented line-to-line does not subside at least up to 18 years after implantation.
我们评估了155例患者接受的164例初次连续Charnley-Kerboull全髋关节置换术的体内迁移模式。股骨准备包括去除骨干松质骨，以便在逐线骨水泥固定前获得假体柄的初始旋转稳定性。我们使用Ein Bild Roentgen Analyse股骨假体评估方法来评估股骨假体的下沉情况。平均随访17.3年（15.1至18.3年）时，73例患者仍存活且未进行翻修，8例已进行翻修，66例已死亡，8例失访。整个系列的平均下沉量为0.63毫米（0.0至1.94毫米）。当采用1.5毫米的阈值时，只有4个假体柄被认为发生了下沉。我们的研究表明，在大多数情况下，逐线骨水泥固定的高度抛光双锥度假体柄至少在植入后18年内不会下沉。
