Multiple approaches for fixation of distal radius fractures exist; nonetheless, there is no consensus on the optimal treatment for these injuries. Although using volar locking plates has become increasingly common as a surgical intervention, the usefulness of bone augmentation remains debatable. Therefore, this study aimed to evaluate the necessity of bone augmentation for distal radius fractures fixed with a volar locking plate. This retrospective study enrolled patients with a single distal radius fracture treated with a volar locking plate between January 2014 and December 2016. Overall, 105 fractures were included and divided into two groups (non-bone augmentation: group 1, n = 88; bone augmentation: group 2, n = 17). Images were reviewed, and dorsal cortex collapse, volar tilting, and radial height and inclination were measured immediately after surgery and at the 6-month follow-up. Both groups exhibited significant differences in dorsal collapse (p < 0.001 and p = 0.001, respectively) and radial height shortening (p < 0.001 and p = 0.039, respectively); volar tilting and radial inclination did not differ significantly. There was no difference in the degree of dorsal collapse (p = 0.715) and radial height shortening (p = 0.651) between the two groups. Of the 105 fractures, 54 were identified as comminuted type according to the AO classification (A3, C2, and C3), and similar radiographic outcomes were noted. Volar locking plates for the treatment of distal radius fractures with or without bone augmentation do not affect the radiographic outcomes. In comminuted fractures, additional bone augmentation is unnecessary if intraoperative anatomical reduction and fixation are performed when possible.

评估用手掌锁定板固定distal骨远端骨折的骨增长的必要性：一项回顾性研究

存在多种固定radius骨远端骨折的方法。但是，对于这些损伤的最佳治疗方法尚未达成共识。尽管使用掌侧锁定板作为外科手术已变得越来越普遍，但是骨增大的有用性仍有待商bat。因此，本研究旨在评估用手掌锁定板固定radius骨远端骨折的骨质增强的必要性。这项回顾性研究招募了2014年1月至2016年12月间使用掌侧锁骨板治疗的单一distal骨远端骨折的患者。总共纳入了105例骨折，分为两组（非骨增强：第1组，n = 88；骨增强：第2组，n = 17）。审查图像，并观察背背皮质塌陷，掌侧倾斜，术后和术后6个月立即测量radial骨高度和倾斜度。两组在背侧塌陷（分别为p <0.001和p = 0.001）和radial骨高度缩短（分别为p <0.001和p = 0.039）上均表现出显着差异。掌侧倾斜度和径向倾斜度无明显差异。两组之间的背侧塌陷度（p = 0.715）和radial骨高度缩短（p = 0.651）没有差异。根据AO分类（A3，C2和C3），在105处骨折中，有54处被确定为粉碎性骨折，并记录了相似的影像学结果。伴有或不伴有骨增大的掌侧locking骨固定板不影响放射线照相结果。在粉碎性骨折中
