Triangular Fibrocartilage Complex (TFCC) Injury is a common diagnosis for patients who complain 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.
Some common causes of TFCC injury include:
- A fall onto the 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.
the diagnosis can be made with a plain radiograph, wrist arthrogram and MRIs. Treatment of this injury consists of conservative with splinting and analgesia to arthroscopic or open TFCC.
