桡骨远端骨折

Distal radial fractures

根据四项回顾性队列研究的结论，目前尚不能推断在治疗桡骨远端骨折时，是采用背侧钢板固定有利还是采用掌侧钢板固定有利。研究认为采用背侧钢板固定更有利于掌倾角的恢复，但是，总体上两种固定方法在其他影像学表现和功能活动度评价方面没有显著性差异。采用背侧钢板固定的患者屈伸活动似乎有少许丢失，但是并没有对两种固定方法在这方面进行比较分析的研究。在所有的研究中，选择何种固定方法主要取决于外科医生的判断，因此关于预后的比较就难免会出现偏倚。

There is insufficient evidence from four retrospective cohort studies to infer the advantage of either the volar or dorsal plating approach for treatment of distal radius fractures. Results suggest that dorsal plating may be more effective for restoration of palmar tilt. Overall, no differences in other radiographic measures or functional mobility were seen. There was tendency for patients with dorsal plates to have less motion for flexion and extension, but statistical comparison with volar plating was not reported. In all studies, plating choice was made based on surgeon discretion,
