Triangular FibroCartilage (TFC) Tear

spi-common-wrist-hand-fingers-460x230

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
