The use of dry arthroscopy allows pinpointing the rupture point of the fibrocartilavo more accurately than other diagnostic technics, both in the identification of pathology and in its surgical resolution.
Finally tears of the TFCC are frequently found by patients with distal radius fractures. Rest can reduce pain and activity can make it worse, especially with rotating movements supination and pronation of the wrist or movements of the hand sideways in ulnar direction.
The central portion of the TFC is thin and consists of chondroid fibrocartilage; this type of tissue is often seen in structures that can bear compressive loads.
