Triangular fibrocartilage complex is a major stabilizer of the distal radioulnar joint (DRUJ). However, triangular fibrocartilage complex (TFCC) tear is difficult to be diagnosed on MRI for its intrinsic small and thin structure with complex anatomy. The purpose of this article is to review the anatomy of TFCC, state of art MRI imaging technique, normal appearance and features of tear on MRI according to the Palmar's classification. Atypical tear and limitations of MRI in diagnosis of TFCC tear are also discussed.
三角纤维软骨复合体是桡尺远侧关节(DRUJ)的主要稳定结构。然而,由于三角纤维软骨复合体(TFCC)本身结构细小且解剖结构复杂,其撕裂在磁共振成像(MRI)上难以诊断。本文旨在回顾TFCC的解剖结构、当前先进的MRI成像技术、MRI上的正常表现以及根据帕尔马分类法的撕裂特征。还将讨论TFCC撕裂的非典型撕裂及MRI诊断的局限性。
