The major cartilaginous injury involving the wrist is to the triangular fibrocartilage complex (TFCC). This is positioned between the ulna and carpus. It usually presents with pain on the pinky side of your wrist. The complex is not only cartilaginous disc but also ligaments. Its job is to stabilise the joint between the two bones of your forearm and provide shock absorption. When there is a shearing force and a compressive load the TFCC can be inflamed and occasionally tear. It is commonly seen in tennis, badminton, ruby and Aussie Rules football.
Signs and Symptoms
- Pain and swelling on the pinky side of the wrist
- A clicking or grinding feeling with movement
- Weakness with grip strength
Treatment usually begins with manual therapy including joint mobilisations, frictions, taping and electrotherapeutic modalities. If there are racquet sports involved then there may be a change of technique required. There may also be need for bracing to allow healing to take place. The wrist also needs to be strengthened following the injury to future proof the wrist.
