[Pathology of the triangular fibrocartilaginous complex in distal radius fractures].

Distal radius fracture is actually quite rarely isolated and triangular fibrocartilaginous complex (TFCC) is often involved with the same mechanism of injury. A contemporary management of the treatment of the initial fracture is ideal and so benefits from a routine arthroscopic management. Nevertheless, in the absence of diagnosis and therefore early treatment, the symptoms may be located at the ulnar crossroads and justify specific treatment of TFCC. It is generally conducted after an accurate arthroscopic lesion classification guiding a procedure, depending on the lesion vascularization as well as its possible destabilization potential (debridement, capsular suture or foveal reattachment). Unfortunately, too often the radius fracture is insufficiently stabilized by an inadequate fixation process or inappropriate orthopedic management with a positive ulnar variance consequence and an ulnar plus syndrome. A "wafer procedure" may then sometimes be proposed if a shortening of less than 3mm is needed and that the distal radio-ulnar joint is not too disorganized.
