A ten-year roentgenologic follow-up study was made of the results of 326 total hip arthroplasties in 256 patients. Seventy-two percent of the living patients are included in the study. Clinical results at ten years were good in 87% of the patients, fair in 7%, and poor in 6%. The incidence of femoral component loosening was 9% at ten years. There was no correlation between femoral component loosening and calcar resorption. The incidence of acetabular component loosening at ten years was 7.9%. Of six hips with calcar resorption greater than 5 mm, three had loose acetabula. Most of these components shown to be loose roentgenologically were clinically asymptomatic. One and one-half percent were revised because of loosening.
对256例患者的326例全髋关节置换术结果进行了为期十年的X线随访研究。纳入研究的患者占在世患者的72%。十年时的临床结果显示，87%的患者良好，7%的患者尚可，6%的患者较差。十年时股骨假体松动的发生率为9%。股骨假体松动与股骨距吸收之间无相关性。十年时髋臼假体松动的发生率为7.9%。在6个股骨距吸收大于5mm的髋关节中，3个髋臼出现松动。大多数X线显示松动的假体临床上无症状。1.5%的患者因假体松动而进行了翻修。
