title: Humeral cup fixation in rheumatoid shoulders. Roentgen stereophotogrammetry of 12 cases.
abstract: Twelve shoulders in 10 patients with rheumatoid arthritis were treated with cemented cup hemiarthroplasty and examined by roentgen stereo photogrammetry during the first year after surgery. One cup migrated 0.5 mm while 11 remained well fixed. Our findings suggest that long-term prosthetic fixation may be achieved.
