WebSep 17, 2024 · The traditional method of foveal TFCC repair involves an open surgical approach through the floor of the 5th dorsal compartment. However, this open approach causes disruption of structures such as the dorsal ulnocarpal capsule, the extensor retinaculum, and, potentially, the distal radioulnar ligament (DRUL). WebThe ulnar pull test in the coronal plane detected a significant increase in diastasis relative to the intact DRUJ after sectioning of the dorsal and volar radioulnar ligaments (2 mm), the foveal insertion of the TFCC (2.6 mm), and the DOB (4.4 mm).
