An Unusual Localization of Lunate in a Transcaphoid Volar Lunate Dislocation: Recent Development

An Unusual Localization of Lunate in a Transcaphoid Volar Lunate Dislocation: Recent Development

Perilunate dislocation and fracture dislocations are rare injuries corresponding to 10% of all carpal injuries. Usually come with high energy trauma, with associated injuries representing 61%. Volar lunate dislocation or fracture- dislocation accounts to 3% of perilunate injuries. We present a case of a 42 years old polytrauma male, transmitted in our department 48 hours after a car accident with a trans-scaphoid volar lunate dislocation. During operation the lunate was displaced volarly to the ulnar side of the wrist, forward to styloid process of distal ulna, while the scaphoid fracture appeared at waist with comminution and the proximal pole of scaphoid protruded under the dorsal capsule. Carpal injuries are often missed out in polytrauma patients and these injuries are underestimated because of the severity of the other visceral or extremity lesions. Untreated or improperly treated those injuries, leads to serious morbidity and loss of function. Therefore good functional prognosis with decreased percentage of complications can be achieved following early recognition and early open surgical repairing ligamentous complex.
