Four cases of locked finger metacarpophalangeal joints are reported. Two of these cases were caused by entrapment of the sesamoid behind an exostosis off the second metacarpal head. The third was from subluxation of the dorsal interosseous tendon over a dorsal osteophyte on the metacarpal. The fourth was from an exostosis tethering the accessory collateral ligament. Surgical exploration using a palmar approach was the treatment of choice. All patients regained full range of motion within two months. A review of the various causes and treatment options for this unusual condition is presented.
本文报道了4例掌指关节交锁病例。其中2例是由于籽骨嵌顿于第二掌骨头的骨赘后方所致。第3例是由于背侧骨间肌腱在掌骨背侧骨赘上半脱位引起。第4例是由于骨赘束缚副侧副韧带所致。采用掌侧入路进行手术探查是首选的治疗方法。所有患者均在两个月内恢复了全范围活动。本文还对这种罕见病症的各种病因及治疗选择进行了综述。
