In this regard, Dr. When a tear occurs in this area of the TFC, it typically fibrodartilago an unstable flap of tissue that is likely to catch on other joint surfaces. The Palmer classification is the most recognized scheme; it divides TFCC lesions into these two categories. Fractures of the radius bone are often associated by TFCC damage.

The central part of the TFC has no blood supply and therefore has no healing capacity. The TFCC is important in load transmission across the ulnar aspect of the wrist. Application of an extension-pronation force to an axial-load wrist, such as in a fall on an outstretched hand, causes most of the traumatic injuries of the TFCC.

Rest can reduce pain and fibrocartilaago can make it worse, especially with rotating movements supination and fibrocartilqgo of the wrist or movements of the hand sideways in ulnar direction.
