Radiological changes in the calcar femoris after total hip replacement, in 97 hips where an extreme valgus position of the prosthesis had been achieved, were compared with 119 hips where the alignment of the prosthesis ranged from varus to only a moderate degree of valgus. In the series with extreme valgus there was a minimum of 1 cm of cement between the calcar femoris and the prosthesis, whereas in the other series the thickness of cement averaged 4.5 mm. In the series with thick cement destructive changes in the calcar were reduced by a factor of 10 and there were no examples of incipient subsidence of the femoral prosthesis. This comparison was based on a follow-up of only 2 years.
对97例实现了假体极度外翻位的全髋关节置换术后股骨距的放射学改变，与119例假体对线从内翻到仅中度外翻的髋关节进行了比较。在极度外翻组中，股骨距与假体之间至少有1厘米的骨水泥，而在另一组中骨水泥厚度平均为4.5毫米。在骨水泥较厚的组中，股骨距的破坏改变减少了10倍，且没有股骨假体早期下沉的例子。该比较仅基于2年的随访。
