[Prosthesis implantation of the rheumatoid arthritis shoulder].
Omarthritis occurs frequently during the early course of rheumatoid arthritis. Many rheumatoid patients ignore omarthritis because of the good compensation mechanism of the shoulder. Sonography and tomography enable early diagnosis of omarthritis before deterioration is radiologically visible. Arthroplasty gives better results when the musculotendinous rotator cuff is still intact. Therefore, arthroplasty should be performed before severe damage develops. Early indication for cup arthroplasty of the humeral head is justified because of better options in revision surgery. Glenoid components show a high incidence of radiolucency and loosening in rheumatoid patients. Cemented hemiarthroplasties show the lowest rate of loosening.
