TFCC
Pronunciation: T-F-C-C
Also written as: TFCC — Triangular Fibrocartilage Complex
The triangular fibrocartilage complex, a structure providing stability to the distal radioulnar joint.
Full Definition
The triangular fibrocartilage complex (TFCC) is an anatomical structure located on the ulnar side of the wrist that provides stability to the distal radioulnar joint and serves as a shock absorber for ulnar-sided wrist loads. The TFCC consists of the triangular fibrocartilage disc, dorsal and volar radioulnar ligaments, ulnocarpal ligaments, and the extensor carpi ulnaris tendon sheath. Injuries to the TFCC are common in athletes and can cause ulnar-sided wrist pain, clicking, and instability. Diagnosis often requires MRI or arthroscopy, and treatment ranges from conservative management to surgical repair.
