Palmar Lunate Trans-Scaphoid, Trans-Triquetral Fracture-Dislocation

Abstract

A palmar lunate dislocation associated with fractures of the scaphoid and triquetrum and an avulsion fracture of the radial styloid is described. The injury resulted from a high energy dorsiflexion/axial compression force. Open reduction of the dislocated lunate and internal fixation of the scaphoid were done as an emergency procedure. A second operation was required to internally fix the displaced triquetral fracture and reduce the lunotriquetral dissociation. A good result was documented at 6 months.
