目的 比较改良小夹板固定与传统石膏固定治疗桡骨远端骨折的临床疗效。方法 选取2019年1月—2021年12月收治的桡骨远端骨折患者64例,分别给予改良小夹板固定（32例）,及石膏外固定（32例）。随访3个月,依照Gartland-Werley腕关节功能评分比较两组治疗效果的优良率以及末次随访时的腕关节Cooney评分,评判治疗效果优劣。结果 改良小夹板固定组89.7%的优良率,传统石膏固定组优良率为82.2%,但差异没有统计学意义（P>0.05）。末次随访时的腕关节Cooney评分,小夹板固定组优良率高于手法复位石膏固定组,差异有统计学意义（P<0.05）。结论 手法复位小夹板固定治疗桡骨远端骨折患者, 可恢复腕关节功能,缓解疼痛,促进骨折愈合,减少并发症的发生,值得临床应用和推广。

Objective To compare the clinical effects of small splint fixation versus plaster fixation on distal radius fractures. Methods From January 2019 to December 2021, a total of 64 patients with distal radius fractures were enrolled into this study. In terms of treatment options, 32 patients received small splint fixation, while the remaining 32 patients had plaster fixation. After 3 months of follow-up, the excellent and good rate of postoperative Gartland-Werley score and the wrist joint function recovery assessed by Wrist Function Cooney scoring system were compared between the two groups. Results The excellent and good rate of the group treated with small splint fixation was 89.7%, while the rate of the group treated with plaster fixation was 82.2%. At last follow-up, the Cooney score of the small splint fixation group was higher than that of the plaster fixation group （P<0.05）. Conclusion Small splint fixation in the treatment of distal radius fractures can improve wrist joint function, reduce pain, promote fracture healing, and reduce complications, which is worthy of clinical application and promotion.
