摘要 目的:探讨儿童掌指关节脱位的损伤机制及最佳治疗途径。方法: 1983~1995年收治新鲜掌指关节脱位8例、陈旧掌指关节脱位3例。11例患儿均为背侧脱位, 食指8例、 拇指2例、中环小指同时脱位1例。闭合整复成功1例,余者均予切开复位。术中见掌骨头自关节囊掌侧薄弱部穿出形成脱位;掌板嵌顿在掌骨头背侧, 掌骨头掌面被掌浅横韧带卡住,阻碍复位。结果: 新鲜掌指关节脱位8例, 治疗效果好;陈旧掌指关节脱位3例, 即便切开复位,仍遗留掌指关节活动明显受限, 1例甚至僵直。结论:强调一旦闭合复位失败, 应及早手术解剖复位。

Eight patients endured with indexfinger dislocation, 2 thumb dislocation and 1 patient with dislocations of the middle,ring and small fingers. Close reduction was successful in one patient. The other patientsrequired open reduction. Operative finding revealed rupture of volar capsule andentrapment of metacarpal heads. The results of the 8 new cases were good. The functioningresult of the 3 old injuries was poor, with one patient suffering persistent stiffness ofthe metacarpophalangeal joint(MCP).
