The treatment of intracapsular hip fractures with total hip arthroplasty in rheumatoid arthritis.
Total hip arthroplasty was performed on 41 patients with rheumatoid arthritis for 43 intracapsular hip fractures from 1971 to 1989. Followup, observation of clinical signs, and radiographs were conducted between one to ten years. Of the 41 patients, 25 had died by the end of the study. Total hip arthroplasty was found to be effective in relieving joint pain, and the walking ability of patients generally recovered to pre-injury status following the operation. Some patients experienced deterioration of the knee and ankle joints due to rheumatoid arthritis, and in such cases there was progressive loss of walking ability. Nevertheless, the function of the hip joint was well preserved, and most patients reported that pain had disappeared and the joint range of motion had returned to normal. In only one case was revision surgery necessary. There was little overall loosening of prostheses, and there were no problems concerning the durability of the artificial joint. The presence, therefore, of femoral neck fractures in patients with rheumatoid arthritis, who are to be encouraged to get out of bed and begin walking as soon as possible, is a strong indication for total hip arthroplasty.
