title: Distal radioulnar joint instability: a review of literature.
abstract: Distal radioulnar joint instability most commonly accompanies fractures of the distal radius and is directly caused by lesion of the triangular fibrocartilage complex, which is the major structure responsible for congruity of the distal radioulnar joint. Acute instability accompanying fractures of the distal radius usually does not require separate management, if the fracture itself is firmly fixated. Chronic instabilities causing persistent pain and wrist dysfunction are treated by arthroscopic reinsertion of the torn attachments of the triangular fibrocartilage. If not possible, radioulnar functional tenodesis is performed using palmaris longus tendon graft, thus restoring joint stability.
