Acute traumatic avulsion or rupture of the ulnar collateral ligament (UCL) of the thumb metacarpophalangeal (TMP) joint is a frequent sports-related injury. If not diagnosed and treated early, it may lead to chronic instability, pain, and loss of pinch and grip strength and possibly osteoarthritis. UCL insufficiency may be treated by various techniques, such as bone anchors, transosseous sutures with or without a pull-out button, tendon grafts, or with TMP joint fusion in neglected cases with arthrosis. A simple technique of internal fixation of an avulsion fracture of the distal attachment of the UCL on the proximal phalanx of the thumb using transosseous sutures is described.
拇指掌指关节（TMP）尺侧副韧带（UCL）的急性创伤性撕脱或断裂是一种常见的运动相关损伤。如果不及早诊断和治疗，可能会导致慢性不稳定、疼痛、捏力和握力丧失，甚至可能引发骨关节炎。UCL功能不全可通过多种技术进行治疗，如骨锚、带或不带拔出纽扣的经骨缝线、肌腱移植，或在伴有关节病的被忽视病例中采用TMP关节融合术。本文描述了一种使用经骨缝线对UCL在拇指近节指骨远端附着处的撕脱骨折进行内固定的简单技术。
