Total hip replacement in irradiated hips. A retrospective study of 71 cases

摘要: We retrospectively reviewed 56 patients (71 hips) treated by total replacement for severe disability after pelvic irradiation. Symptoms were associated with various radiological lesions due to irradiation, including atraumatic femoral-neck fracture, osteonecrosis of the femoral head or acetabulum, and radiation osteitis whole pelvis. From 1970 1982 we used standard cemented components in 49 hips had a high rate acetabular loosening (52%) at mean follow-up 69 months. This was probably mechanical insufficiency irradiated periacetabular bone. 1983 1990 routinely reinforcement rings. The aseptic 22 40 months 19%, but there two septic loosenings emphasising risk infection these patients. When is required an hip, recommend acetabulum using metallic ring, still increased difficult cases such as destruction soft-tissue vascular injuries, Girdlestone procedure may be indicated.
