Triangular Fibrocartilage complex (TFCC) injury is a common diagnosis for the patients who complained of ulnar sided wrist pain. TFCC is a complex ligamentous structure of the wrist which provide stability and a platform for movement to the wrist joint.
Common causes of TFCC injury include:
- Fall onto internally rotated(pronated) and hyperextended wrist
- Power-drill injuries in which the drill binds and rotates the wrist instead of the bit
- Distraction force applied to the volar forearm or wrist
- Distal radius fractures.
Diagnosis can be made with plain radiograph, wrist arthrogram and MRIs. Treatment consists of conservative with splinting and analgesia to arthroscopic or open TFCC.
