Forty-three of 51 Link SP hip prostheses inserted 4 years previous to this study were clinically and radiographically reviewed. All demonstrated bone resorption in excess of 2 mm under the collar, but this resorption was not progressive. No prosthesis had loosened. The collar of a prosthesis, even when securely cemented into the femur with a carefully matched neck cut, was decoupled from its functional position in all the reviewed cases at 4 years. Its only remaining function was to prevent subsidence within the cement mantle, should it ever become necessary to provide stability.
对在本研究前4年植入的51个Link SP髋关节假体中的43个进行了临床和影像学检查。所有假体均显示出假体颈部下方超过2毫米的骨吸收，但这种吸收并未进展。没有假体出现松动。在所有接受检查的病例中，4年后，即使假体的颈部经过精心匹配的切割并牢固地用骨水泥固定在股骨中，其颈部也会从其功能位置脱开。它唯一剩下的功能是在有必要提供稳定性时防止在骨水泥壳内下沉。
