Arthroscopic Ligament-specific Repair for Triangular Fibrocartilage Complex Foveal Avulsion: A Novel Technique.

The deep components of the triangular fibrocartilage complex (TFCC), which consist of the volar and dorsal radioulnar ligaments (RULs), are crucial for maintaining stability of the distal radioulnar joint. Avulsion of the volar and dorsal RULs from their foveal insertions must thus be diagnosed and treated correctly. We describe our arthroscopic technique for TFCC foveal repair (arthroscopic ligament-specific transosseous repair), in which we repair each of the dorsal and volar RUL to separate points on the fovea. With this "ligament-specific" repair we wish to restore the normal anatomy and physiology of the TFCC.
