PURPOSE
Distal radius fractures are associated with a high incidence of triangular fibrocartilage complex (TFCC) tears. This study aims to evaluate the status of TFCC after the healing of distal radius fractures, and its clinical significance.
METHODS
Wrist arthroscopies were performed on 43 distal radius fractures, with an average age of 54 years old.
RESULTS
Twenty-six complete tears and 15 partial healed tears were noted. Five out of eight patients with intact TFCC tears had neither signs nor symptoms, while eight patients with TFCC tears had no complaint. While no association was found between ulnar wrist pain and TFCC tears, there was association between DRUJ instability and TFCC tears and fovea tears. The function outcome did not differ with respect to the integrity of TFCC.
CONCLUSIONS
A large majority of TFCC tears remained unhealed after the union of distal radius fractures. However, not all patients with tear were symptomatic.
目的
桡骨远端骨折与三角纤维软骨复合体（TFCC）撕裂的高发生率相关。本研究旨在评估桡骨远端骨折愈合后TFCC的状况及其临床意义。
方法
对43例桡骨远端骨折患者进行腕关节镜检查，平均年龄54岁。
结果
发现26例完全撕裂和15例部分愈合撕裂。8例TFCC完整撕裂的患者中有5例既无体征也无症状，而8例TFCC撕裂患者无主诉。虽然尺侧腕部疼痛与TFCC撕裂之间未发现关联，但下尺桡关节不稳与TFCC撕裂和中央凹撕裂之间存在关联。TFCC的完整性对功能结果没有影响。
结论
桡骨远端骨折愈合后，绝大多数TFCC撕裂仍未愈合。然而，并非所有撕裂患者都有症状。
