Hand involvement is common in systemic lupus erythematosus, and is different from that seen in rheumatoid arthritis. Raynaud's phenomenon was present in 50 per cent of our patients and, rather than joint deformity and synovitis, often was the primary cause of disability. Deformities in lupus hands are the result of laxity of the supporting soft-tissue structures about the joint. Articular destruction and ankylosis do not occur unless there is coexistent rheumatoid arthritis. Swanneck deformities without tight intrinsics and hyperextension deformity of the thumb interphalangeal joint are characteristic of this disease in the hand.
手部受累在系统性红斑狼疮中很常见，且与类风湿关节炎中的手部表现不同。我们的患者中有50%出现雷诺现象，而且它往往是导致残疾的主要原因，而非关节畸形和滑膜炎。狼疮手部畸形是关节周围支持性软组织结构松弛的结果。除非同时存在类风湿关节炎，否则不会发生关节破坏和关节强直。无紧张性内在肌的鹅颈畸形和拇指指间关节过伸畸形是该病手部表现的特征。
