半环式外固定架治疗C型桡骨远端骨折21例

21 Cases Clinical Report on Half Ring External Fixator on the Treatment of Type C Distal Radius Fracture

目的:采用半环式外固定架治疗C型桡骨远端骨折,观察对桡骨短缩移位的干预,评估其临床疗效。方法:回顾性纳入2016年1月至2019年10月C型桡骨远端骨折患者21例。研究在术前、术后当日、术后3周、6周及半年共5个时间点受试桡骨高度指标情况,进行重复测量资料的方差分析。研究术前、术后6周及半年共3个时间点评估受试Garland-Werley(GW)指标情况,进行重复测量资料的方差分析。结果:桡骨高度方面,术后当日、术后3周及6周时,桡骨高度变化差异无统计学意义(P>0.05)。半年后(即拆除外固定架后)出现高度降低,差异有统计学意义。GW指标在术后半年时明显优于术后6周,差异有统计学意义(P<0.05)。结论:半环式外固定架治疗C型桡骨远端骨折,可发挥其优势,维持桡骨高度并恢复腕关节功能,但固定架拆除后仍会有部分桡骨高度降低。

Objective:To treat type C distal radius fractures by half ring external fixator,observe the intervention of radial shortening and displacement,and evaluate its clinical efficacy and guide clinical application.Methods:21patients with type C distal radius fracture from January 2016to October 2019were retrospectively included.The radial height indexes at 5 time points before operation,after operation,3weeks,6weeks and half a year were studied and the variance of repeated measurement data were analyzed.The Garland-Werley(GW)indexes were evaluated at three time points before operation,6weeks and half a year,and the analysis of variance of repeated measurement data was carried out.Results:There was no significant difference in radial height after operation,3weeks and 6weeks.There was a statistical difference in height reduction after half a year after removing the external fixator.The GW index at half a year after operation was significantly better than that at 6weeks after operation when the external fixator was removed,which was statistically significant.Conclusion:Half ring external fixator can play its advantages in the treatment of type C distal radius fracture,maintain radius height and restore wrist function.However,the height of part of the radius will still be reduced after the removal of the fixator.
