[Complex dislocation fracture of the wrist. Transscaphoid-translunar-transstyloid dislocation fracture].

The most common injuries of the carpus are lunate and perilunate dislocations. The authors describe a complex dislocation of the carpus associated with fractures of the scaphoid, lunate, and styloid process of the radius. The pathogenesis of this dislocation is believed to be extreme hyperextension and radial deviation of the wrist. This mechanism can cause posterior dislocation of the carpus with fracture of scaphoid and lunate.
