Ulnar dislocation of the long extensor tendons of one or more fingers occurred in five elderly women. There was no history of trauma or any of the stigmata of rheumatoid arthritis. In all fingers there was loss of active extension in the metacarpophalangeal joints following flexion. It is postulated that this is a definite clinical entity occurring in the elderly associated with excessive joint laxity.
5名老年女性出现一根或多根手指的长伸肌腱尺侧脱位。无创伤史或类风湿关节炎的任何体征。所有手指在掌指关节屈曲后主动伸直功能丧失。据推测，这是一种发生在老年人中的明确临床病症，与关节过度松弛有关。
