Despite frequent involvement, the rheumatoid shoulder is neglected in operative treatment of the upper extremities. The slow course of omarthritis, the compensation mechanism of scapulothoracic motion and neighbouring joints as well as dominating disabilities of the lower extremities and the rheumatoid hand are possible explanations. The pattern of destruction of the rheumatoid shoulder is characterized by progressive joint and soft tissue deterioration. ⋯ Patients with irreparable rotator cuff tears and severe glenohumeral arthritis remain a difficult challenge in shoulder surgery and the ideal procedure has not yet been found. Pain relief and a modest increase in active motion are the main goals in operative treatment. Bipolar shoulder arthroplasty represents an adequate alternative to currently favoured hemiarthroplasty in patients with cuff-deficient shoulders.
