[Bone scintigraphy in patients with hip joint prostheses. Use of bone scintigraphy in hip pain after total hip replacement].

A retrospective investigation was undertaken to assess the value of bone scintigraphy with 99mtechnetium methylene-diphosphonate in patients referred with hip pain after total hip replacement. The material comprized 68 patients with a total of 68 prostheses. This review revealed that 10/25 of the patients with pathological scintigrams and 6/28 of the patients with normal scintigrams were submitted to replacement of the prostheses. In the way in which it was carried out and interpreted in this department, scintigraphy was of limited value in selection of the patients who required replacement of the prostheses.
