Arthroscopic Evaluation of the Foveal Attachment of the Triangular Fibrocartilage

Anatomical and biomechanical studies have highlighted the importance of the deep attachment of the TFCC for maintaining stability of the distal radioulnar joint (DRUJ). The standard arthroscopic assessment of the TFCC does not allow one to definitively determine whether the deep fibers are indeed intact, and establishing the diagnosis of a foveal detachment remains an exacting challenge. DRUJ arthroscopy is useful to assess the foveal fibers in any patient with DRUJ instability and can aid in the surgical decision making.
