Central perforation of the articular disc of the triangular fibrocartilage complex in a 17-year-old girl: could it be congenital?

A case of a central perforation of the horizontal portion of the triangular fibrocartilage complex in a 17-year-old girl is reported. The age of the patient, along with normal articular surfaces of the ulnar head and ulnar carpus and the lack of an ulnar-positive wrist, made the existence of a degenerative tear unlikely. The possibility that the central perforation in this patient could be congenital suggests that this defect should be considered in the differential diagnosis of ulnar-sided wrist pain in the young patient.
