What is a TFCC tear?
Understanding your injury – Brisbane Physiotherapy Edition.
Overview of TFCC tears:
Description
- The triangular fibrocartilage complex (TFCC) lies between the ulnar and the carpus (small bones that form the wrist and part of the hand)
- It is a load-bearing structure and is also the major stabilizer of the distal radioulnar joint.
- The TFCC is a common site of wrist pain and is reported to accompany distal radius fractures in 39% to 84% of cases.
Anatomy
- The ‘complex’ consists of the triangular fibrocartilage, ulnar meniscus homolog, ulnar collateral ligament, numerous carpal ligaments and the extensor carpi ulnar tendon sheath.
Presentation
- Mechanism of injury: compressive loads to the wrist (e.g. gymnastics, diving, golf and racquet sports) may tear the central portion of the cartilage. It can also be disrupted after a distal radial-ulnar fracture or potential with disruption to the distal radioulnar joint.
- Tenderness and swelling over the ulnar aspect of the wrist.
- Pain on resisted wrist movements
- Clicking with wrist range of movement
- Reduced grip strength
- Positive finding on TFCC compression test
- Recreation of symptoms with pushing self up from a sitting position.
