The aim of this study was to detect the severity of ulnar variance (UV) compared with contralateral hand on postoperative wrist function in patients with distal radius fracture. 116 cases with unilateral distal radius fracture were retrospectively analyzed and divided into high or low UV severity groups (Dividing value = 2.5 mm). The following parameters were used to evaluate the effect: palmar tilt, radial inclination, VAS score, DASH score and wrist function. The severity of UV existed widely, accounting for 93.1% (108 cases). The severity of UV correlated with palmar tilt, radial inclination, grip strength, VAS score, DASH score and the wrist function (P < 0.05). Log-rank analysis showed that the severity of UV, palmar tilt, radial inclination were important factors influencing the joint function postoperatively (P < 0.0 5). Multivariate analysis confirmed that the severity of UV was an independent and significant factor on wrist function (P = 0.010). And the palmar tilt was also an important factor influencing wrist function (P = 0.047). The severity of ulnar variance compared with contralateral hand is an independent and significant factor on wrist function, which should be considered as an important step during preoperative plan.
本研究旨在检测尺侧骨变异（UV）的严重程度与桡骨远端骨折患者术后腕关节功能的对侧手相比。回顾性分析 116 例单侧桡骨远端骨折患者，分为高或低 UV 严重程度组（分界值=2.5mm）。采用以下参数评估疗效：掌倾角、桡偏角、VAS 评分、DASH 评分和腕关节功能。UV 的严重程度差异很大，占 93.1%（108 例）。UV 的严重程度与掌倾角、桡偏角、握力、VAS 评分、DASH 评分和腕关节功能相关（P<0.05）。对数秩分析显示，UV 严重程度、掌倾角、桡偏角是影响术后关节功能的重要因素（P<0.05）。多因素分析证实，UV 严重程度是腕关节功能的独立显著因素（P=0.010）。掌倾角也是影响腕关节功能的重要因素（P=0.047）。与对侧手相比，尺侧骨变异的严重程度是腕关节功能的独立显著因素，在术前计划中应将其视为重要步骤。
