Intracarpal ligamentous tears and fractures of the radius often have a similar mechanism. For instance, no prospective studies have defined the real incidence of such associations, which are not antagonistic. The authors performed a systematic operative wrist arthrogram during distal radius fractures in a group of 58 patients with a mean age less than 50 years. Such a population was at low risk of degenerative ligamentous tears. Triangular fibrocartilage complex was torn in two-thirds of all types fractures. Extra-articular radius fractures were associated with an intracarpal ligamentous tear in 25% and always a luno-triquetral lesion type. In contrast, intra-articular and radius styloid fractures were frequently associated with a scapho-lunate lesion.
腕骨间韧带撕裂和桡骨骨折通常具有相似的机制。例如，尚无前瞻性研究明确此类关联的实际发生率，而它们并非相互排斥。作者对一组平均年龄小于50岁的58例桡骨远端骨折患者进行了系统性的手术腕关节造影。这样的人群发生退行性韧带撕裂的风险较低。在所有类型的骨折中，三分之二存在三角纤维软骨复合体撕裂。关节外桡骨骨折中有25%伴有腕骨间韧带撕裂，且总是月三角骨损伤类型。相比之下，关节内和桡骨茎突骨折常伴有舟月骨损伤。
