This study aims to evaluate the mid-term functional and radiological outcomes of magnesium-based screws in the treatment of scaphoid fractures.
Between February 2015 and February 2018, a total of 21 patients (18 males, 3 females; mean age: 28.5±5.8 years; range, 19 to 39 years) with acute scaphoid waist fractures who underwent fracture fixation with biologically degradable magnesium-based compression screws were retrospectively analyzed. Fractures were classified according to the Herbert and Fisher classification. The absence of pain on palpation and painless active range of motion were accepted as the signs of union.
The mean follow-up was 43.3±5.3 (range, 36 to 52) months. According to the Herbert and Fisher classification, nine patients had type B1 and 12 patients had type B2 scaphoid fractures. Union was achieved in all cases. The mean time to union was 11.2±1.5 (range, 9 to 14) weeks. The mean grip strength, flexion, and extension were 43.57°, 73.57°, and 76.43°, respectively. The grip strength, pinch strength, and range of motion of the operated side were evaluated at the final follow-up visit and compared with the contralateral side (control group). No complication occurred. Any screw was not removed.
Magnesium-based compression screws can be safely used for acute scaphoid fractures considering their favorable functional and radiological results.
本研究旨在评估镁基螺钉治疗舟状骨骨折的中期功能和影像学结果。
2015 年 2 月至 2018 年 2 月，回顾性分析了 21 例（18 名男性，3 名女性；平均年龄 28.5±5.8 岁；年龄范围 19 至 39 岁）接受生物可降解镁基加压螺钉固定治疗的急性舟状骨腰部骨折患者。骨折根据 Herbert 和 Fisher 分类进行分类。无触压痛和无痛主动活动范围被认为是愈合的标志。
平均随访时间为 43.3±5.3（范围 36 至 52）个月。根据 Herbert 和 Fisher 分类，9 例为 B1 型，12 例为 B2 型舟状骨骨折。所有病例均达到愈合。愈合的平均时间为 11.2±1.5（范围 9 至 14）周。平均握力、屈曲和伸展分别为 43.57°、73.57°和 76.43°。在末次随访时评估了患侧的握力、捏力和活动范围，并与对侧（对照组）进行比较。未发生任何并发症。任何螺钉均未取出。
考虑到镁基加压螺钉良好的功能和影像学结果，其可安全用于治疗急性舟状骨骨折。
