TFCC – a common wrist injury (signs and symptoms)

shutterstock_179809730The Triangular Fibrocartilage Complex (TFCC) is a complex structure within the wrist, which acts as a major stabiliser of the joints between the two forearm bones (distal radioulnar joint) and also between the ulna (forearm) and the carpal bones (the hand). The TFCC helps to transmit the load from the wrist to the forearm, as well as assist in complex movements of the wrist.

The TFCC is susceptible to injury, commonly either traumatic or degenerate.

Traumatic injuries such as falling onto an outstretched hand or degenerate in nature (wear and tear). Risk factors include:

  • Previous history of wrist fractures
  • Gout
  • Rheumatoid arthritis
  • Chronic overloading of the wrist mainly related to sport or occupation
  • Anatomical abnormalities in the forearm bones such as the ulna being longer than the radius (bones of the forearm)=
  • Increasing age

Symptoms of TFCC injury include:

  • Pain on the ulnar side (little finger side) of the wrist  +/- clicking sensation
  • Swelling over the ulnar side of the wrist
  • Reduced grip strength
  • Difficulty weight bearing on that wrist through the hand
  • Pain that is worse with twisting or rotational movement ie) opening a jar, lifting heavy objects
