Abstract：
A 55-year-old woman presented with multiple episodes of falls that injured her right thumb and restricted her daily activities because of pain and instability. Ultrasound found the rare proximal metacarpal UCL avulsion. The repair was done using suture anchors under wide-awake anaesthesia with no tourniquet (WALANT). The patient regained her thumb movements, got a stable MCP joint, and remained symptom-free at one year of follow-up. Proximal avulsion of the UCL is rare. Ultrasound confirms the avulsion, and surgical reconstruction under wide-awake anaesthesia allows the surgeon and the patient to assess and appreciate the MCP joint stability, thereby efficiently rehabilitating the patient. The functional outcome of proximal UCL repair is good. This report describes a rare presentation of the proximal metacarpal attachment avulsion injury of the ulnar collateral ligament (UCL) in a thumb and reviews the management.
摘要：
一名55岁的妇女出现多次跌倒，由于疼痛和不稳定，右手拇指受伤并限制了日常活动。超声发现罕见的掌骨近端UCL撕脱。修复是在无止血带的全醒麻醉下使用缝合锚钉（WALANT）进行的。病人恢复了拇指的运动,有一个稳定的MCP关节,在随访一年时仍无症状。UCL的近端撕脱很少见。超声波确认撕脱,全醒麻醉下的手术重建使外科医生和患者能够评估和欣赏MCP关节的稳定性，从而有效地恢复病人。近端UCL修复的功能结果良好。本报告描述了拇指中尺侧副韧带（UCL）的近端掌骨附着撕脱伤的罕见表现，并回顾了治疗方法。
