Most distal radius fractures are associated with distal ulnar fractures. However, there is still a lack of consensus on the incidence of different types of distal ulnar fractures among adults in China. Therefore, we analyzed the incidence of distal radial fractures with and without associated distal ulnar fractures among adults in a southern China county from 2010 to 2020. Registry data of 2333 patients (2351 sides) with a distal radius fracture from 2010 to 2020 underwent evaluation, encompassing parameters such as age, sex, distal radius fracture classification, fracture side, and distal ulnar fracture classification. Distal radial fractures were classified according to the AO/OTA classification. Distal ulnar fractures were examined using the Q-modifier classification. 1719 females (73.68%) and 614 males (26.32%) were included in the study. Compared to men, the incidence of distal radial fractures accompanying distal ulnar fractures in women was approximately 2.8 times higher. Additionally, 49.81% of distal radius fractures were associated with fractures of the distal ulna, while 46.44% were associated with fractures of the ulnar styloid. The most common fracture type was that of the ulnar styloid Q1 (93.73%). The mean age of female patients was 61.71 ± 12.13, while male patients had an average age of 50.63 ± 14.86. The Q1 type was the most common type of distal ulnar fracture. We also found that more females (age range: 50 years or older) had type C distal radius fractures compared to males. However, type B fractures were observed more frequently in males than in females (range: 18-49 years). Osteoporosis was believed to be the main cause of fractures in women aged >50 years old. Moreover, the peak incidence of radius fractures in males was lower than in females in different age groups.
大多数桡骨远端骨折与尺骨远端骨折相关。然而，目前仍缺乏中国成年人不同类型尺骨远端骨折发生率的共识。因此，我们分析了 2010 年至 2020 年中国南方某县成年人桡骨远端骨折伴或不伴尺骨远端骨折的发生率。对 2010 年至 2020 年 2333 例桡骨远端骨折患者（2351 侧）的登记数据进行了评估，包括年龄、性别、桡骨远端骨折分类、骨折侧和尺骨远端骨折分类等参数。桡骨远端骨折采用 AO/OTA 分类。尺骨远端骨折采用 Q 修正分类。研究纳入 1719 例女性（73.68%）和 614 例男性（26.32%）。与男性相比，女性桡骨远端骨折伴尺骨远端骨折的发生率约为男性的 2.8 倍。此外，49.81%的桡骨远端骨折合并尺骨远端骨折，46.44%的桡骨远端骨折合并尺骨茎突骨折。最常见的骨折类型是尺骨茎突 Q1 型（93.73%）。女性患者的平均年龄为 61.71±12.13 岁，男性患者的平均年龄为 50.63±14.86 岁。Q1 型是最常见的尺骨远端骨折类型。我们还发现，与男性相比，更多女性（年龄范围：50 岁及以上）发生 C 型桡骨远端骨折。然而，B 型骨折在男性中比在女性中更为常见（年龄范围：18-49 岁）。骨质疏松症被认为是 50 岁以上女性骨折的主要原因。此外，不同年龄组男性桡骨骨折的发病率峰值均低于女性。
