TFCC stabilizes the distal radioulnar joint and dissipates ulnar‑sided load. Palpable 'fovea sign', ulnar grind, and DRUJ shift test support diagnosis. MRI useful; wrist arthroscopy remains gold standard for diagnosis and treatment. Central tears → arthroscopic debridement; peripheral tears → repair; positive ulnar variance → consider ulnar shortening osteotomy. Failure to treat instability leads to chronic pain and DRUJ arthritis.
