Ulnar-sided contrast leakage in different patients with traumatic lesions of the triangular fibrocartilage complex (TFCC). A Injury of the peripheral TFCC attachments associated with a displaced radius fracture. B Complex TFCC injury affecting the articular disc and the ulnar-sided periphery. C Impacted radius fracture resulting in ulna plus variance with an articular disc lesion and rupture of both peripheral TFCC insertions
