Triangular fibrocartilage complex (TFCC) tears are a common source of ulnar sided wrist pain.
Originally described by Palmer, in 1981, as a complex of several structures, our understanding of the anatomy and the function of the TFCC has been refined by histologic studies. The TFCC plays an important role in load bearing across the wrist as well as in distal radioulnar joint (DRUJ) stabilization.
Acute injuries to the structures may involve one or more components. The clinician evaluating patients with ulnar wrist pain must attempt to define which components are involved. Management of an acute ulnar wrist injury begins with defining the specific anatomic structures that have been disrupted and the degree to which they have been disrupted with options being open versus keyhole surgery.
