[Trans-scapho-perilunar dislocations with internal instability of the carpal bones].
The authors have shown both in patients and in cadavers that the posterior triquetro-lunate ligament plays a major role in the stability of the carpus. They suggest a new concept associating pronation and dorsal flexion of the wrist, the hand being immobilised, to explain instability following perilunate dislocations with fractures of the scaphoid. They recommend both the fixation of the scaphoid fracture by a screw and primary repair of the triquetro-lunate ligament.
