Intramedullary screws (IMS) have become a viable option for metacarpal fracture fixation. To further appraise their utility, this study assessed clinical and patient-reported short- and medium-term outcomes of IMS fixation for extra-articular metacarpal fractures. A retrospective cohort study was performed in a series of 32 patients (with a total of 37 fractures) who underwent metacarpal fracture fixation over a 42-month period between January 2020 and July 2023. Mean time for return to work was 39.8 days; mean time for return to full function was 88.4 days; total active motion was 250.7° (range: 204.9-270.9); Quick Disabilities of the Arm, Shoulder and Hand score was 2.3 (range: 0-22.7); mean visual analogue pain score was 0.9 out of 10 (range: 0-6) and a single complication was observed. The use of IMS in metacarpal fracture fixation is a practicable surgical option. IMS fixations yields a satisfactory duration for return to function, good postoperative range of movement, modest pain scores and low rates of complications. Level IV (Therapeutic).
髓内钉（IMS）已成为掌骨骨折固定的一种可行选择。为了进一步评估其效用，本研究评估了 IMS 固定治疗关节外掌骨骨折的短期和中期临床和患者报告结果。 这是一项回顾性队列研究，共纳入 32 名患者（共 37 处骨折），他们在 2020 年 1 月至 2023 年 7 月的 42 个月期间接受了掌骨骨折固定。 恢复工作的平均时间为 39.8 天；完全恢复功能的平均时间为 88.4 天；总主动活动度为 250.7°（范围：204.9-270.9）；手臂、肩部和手部残疾快速评分（Quick Disabilities of the Arm, Shoulder and Hand score）为 2.3（范围：0-22.7）；视觉模拟疼痛评分平均为 10 分中的 0.9 分（范围：0-6），仅观察到 1 例并发症。 在掌骨骨折固定中使用 IMS 是一种可行的手术选择。IMS 固定可实现令人满意的功能恢复时间、良好的术后活动范围、适度的疼痛评分和较低的并发症发生率。 等级 IV（治疗）。
