The TFC is a triangular shaped piece of cartilage at the end of the forearm bones on the side of the little finger. It helps to complete the wrist joint. A tear/strain of the TFC commonly occurs when compressive/twisting loads are placed through the wrist, which can happen via repetitive strain e.g. a gymnast doing cartwheels, or a fall onto the wrist.
Signs and Symptoms:
- History of repetitive trauma to wrist.
- Painful movement of wrist.
- Clicking/catching/grinding with wrist movements.
- Pain worsens with activity.
- Weakness especially with grip strength.
