Trans-scaphoid and trans-capitate perilunate fracture-dislocation of the wrist with concomitant ipsilateral fractures: a case report

Of all wrist dislocation, the perilunate is the most common type of dislocation. There is ligament disruption typically begins radially and propagates around the lunate. It may be associated with different carpal fractures which the most common pattern is the trans-scaphoid perilunate fracture-dislocation [1,2] which constitutes approximately 50% of these injuries [1-5]. Injury to the distal radius, ulna and carpal bones may accompany the perilunate dislocations which depend on the mechanism and the type of injury involved [6]. We describe a case of dorsal trans-scaphoid trans-capitate perilunate fracture-dislocation together with posterior olecranon fracture-dislocation of the left upper extremity. The clinical, radiologic, and surgical approaches related to this case are discussed.
