Preoperative planning is important for the osteosynthesis of distal radius fractures. Challenges arise for patients presenting with bilateral wrist injuries or a history of contralateral wrist injuries. In such cases, the estimation of the distal radius morphology and the determination of the plate size from the preoperative physical characteristics could prove beneficial. The objective of this study was to investigate the correlation between the physical characteristics and the morphology of the distal radius articular surface. A total of 79 wrist computed tomography (CT) images (41 women and 38 men) were evaluated. Physical characteristics, such as height, weight, and body mass index (BMI), were recorded. Three-dimensional CT analysis was performed to investigate the transverse and anteroposterior diameters of the distal radius. Pearson's correlation coefficient was used to assess the relationships between height, weight, and BMI and the transverse and anteroposterior diameters of the distal radius. A moderate to strong correlation was found in the overall analysis between body height and transverse diameter (r = 0.66). There were also moderate correlations between body height and anteroposterior diameter (r = 0.45) as well as weight and transverse diameter (r = 0.41), both of which were statistically significant ( < 0.001). Our findings indicate a statistically significant correlation between height, weight, and morphology of the distal radius. When analyzed by sex, the correlation between body height and the transverse diameter of the distal radius was found to be relatively strong in women (r = 0.47, = 0.002), suggesting that it could be a useful indicator for preoperative planning, such as estimating plate size.
术前规划对于桡骨远端骨折的接骨术至关重要。对于双侧腕部受伤或有对侧腕部受伤史的患者来说，会出现一些挑战。在这种情况下，根据术前身体特征估计桡骨远端形态并确定钢板尺寸可能会有所帮助。本研究的目的是调查身体特征与桡骨远端关节面形态之间的相关性。共评估了79例腕部计算机断层扫描（CT）图像（41名女性和38名男性）。记录身高、体重和体重指数（BMI）等身体特征。进行三维CT分析以研究桡骨远端的横径和前后径。采用Pearson相关系数评估身高、体重和BMI与桡骨远端横径和前后径之间的关系。在总体分析中发现身高与横径之间存在中度至强相关性（r = 0.66）。身高与前后径（r = 0.45）以及体重与横径（r = 0.41）之间也存在中度相关性，两者均具有统计学意义（<0.001）。我们的研究结果表明身高、体重与桡骨远端形态之间存在统计学上的显著相关性。按性别分析时，发现女性身高与桡骨远端横径之间的相关性相对较强（r = 0.47， = 0.002），这表明它可能是术前规划的一个有用指标，例如估计钢板尺寸。
