Triangular Fibrocartilage Complex
The triangular fibrocartilage (TFC) complex is a combination of cartilage and ligaments found between the bones of the forearm and the wrist on the ulnar (pinky finger) side of the wrist, which acts as a hock absorber transferring forces through the wrist into the forearm.
A TFC injury occurs when cartilage and/or ligaments become torn or damaged.
Symptoms of TFC Complex Injuries:
- Pain during weight bearing activities such as push ups or pushing up from a chair.
- Tenderness at the ulnar side of the wrist.
- Possibly popping or clicking.
Causes of TFC Complex Injuries:
- Trauma such as falling directly onto an outstretched hand.
- Wear and tear resulting from repetitive stress sports such as football, basketball and baseball.
- Natural wear that comes with aging.
A TFC tear is diagnosed after a thorough examination of the wrist. The diagnosis may be confirmed with an MRI scan.
Treatment options include:
- Steroid injections
- Arthroscopic surgery
