The purpose of this study was to investigate the frequency and distribution of associated carpal bone fractures (CBFs) in distal radial fractures (DRFs).
Three hundred and thirteen patients who underwent surgical treatment for DRFs between March 2007 and January 2010 were reviewed retrospectively. In this study, 223 patients who had preoperative computed tomography (CT) were included. We investigated the frequency and distribution of associated CBFs on CT scans. The relationship between the frequency of associated CBFs and patient factors such as age, gender, body mass index, and the mechanism of injury was assessed.
CBFs were complicated in 46 of 223 DRFs (20.9%). The distribution of CBFs was 23 cases in the triquetrum, 16 in the lunate, 12 in the scaphoid, five in the hamate, and four in the pisiform. Among the 46 cases, a fracture of one carpal bone occurred in 36 cases, two in seven cases, three in two cases, and four in one case. In 10 of the 46 cases, associated CBFs occurred in more than two carpal bones. No significant differences were observed for age, sex, body mass index, or the mechanism of injury between patients with DRFs and CBFs and those without CBFs.
Because CBFs that mainly occur in the proximal carpal row are complicated in DRFs at a relatively high frequency, assessment of carpal bones using CT scans is beneficial.
本研究旨在探讨桡骨远端骨折（DRF）中合并腕骨骨折（CBF）的频率和分布。
回顾性分析 2007 年 3 月至 2010 年 1 月期间接受 DRF 手术治疗的 313 例患者。本研究纳入了 223 例术前进行计算机断层扫描（CT）的患者。我们在 CT 扫描上研究了合并 CBF 的频率和分布。评估了合并 CBF 的频率与患者因素（如年龄、性别、体重指数和损伤机制）之间的关系。
223 例 DRF 中有 46 例（20.9%）合并 CBF。CBF 的分布为三角骨 23 例、月骨 16 例、舟骨 12 例、钩骨 5 例、豌豆骨 4 例。在这 46 例中，1 处腕骨骨折 36 例，2 处骨折 7 例，3 处骨折 2 例，4 处骨折 1 例。在 46 例中有 10 例合并了超过 2 处腕骨骨折。DRF 合并 CBF 组和无 CBF 组在年龄、性别、体重指数或损伤机制方面无显著差异。
由于主要发生在近排腕骨的 CBF 在 DRF 中相对较高频率地发生，因此使用 CT 扫描评估腕骨是有益的。
