title: Roentgenologic results of total hip arthroplasty. A ten-year follow-up study.
abstract: 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.
