The purpose of the study was to evaluate clinical and radiological outcomes of extra-articular fractures involving the base of the thumb metacarpal treated with fixation using a retrograde intramedullary cannulated headless screw. A review of prospectively collected data was conducted on a consecutive series of 13 patients, treated with headless screw fixation for acute displaced fractures. All workers resumed full duties, while non-workers returned to unlimited leisure activities within a mean of 42 days. At 3 months follow-up, all range of motion measurements in the treated and untreated thumb were similar. Mean visual analogue pain score was 0.8 at rest and 1.4 during exercise and mean Quick Disabilities of the Arm, Shoulder, and Hand score was 5. All patients achieved radiographic union by 8 weeks. We conclude that the intramedullary headless screw fixation is safe and reliable for base of thumb metacarpal fractures, allowing for early postoperative motion and good functional recovery. IV.
研究目的在于评估采用逆行髓内中空无头螺钉固定治疗累及拇指掌骨基底的关节外骨折的临床和影像学结果。对连续的 13 例急性移位骨折患者进行前瞻性收集数据的回顾性研究，采用无头螺钉固定治疗。所有工人恢复正常工作，而非工人在平均 42 天内恢复无限制的休闲活动。在 3 个月的随访中，治疗组和未治疗组拇指的所有活动范围测量值相似。静息时平均视觉模拟疼痛评分（VAS）为 0.8，运动时为 1.4，平均 Quick Disabilities of the Arm, Shoulder, and Hand（DASH）评分为 5。所有患者均在 8 周时达到影像学愈合。我们得出结论，髓内中空无头螺钉固定治疗拇指掌骨基底骨折安全可靠，可早期进行术后运动，功能恢复良好。
