Abstract

Carpal antelunar dislocations are much rarer than posterior dislocations. Their frequencies are between 3 and 6% of carpal perilunar dislocations. Out of 23 cases of carpal antelunar dislocations listed in the literature, there are only 11 trans-scapho antelunar dislocations. Carpal antelunar dislocation and Fenton syndrome are two exceptional entities in the literature. In the case of Fenton syndrome, the head of the capitatum is described with a rotation of 90o to 180o. The association of these two entities remains anecdotal (3 cases described). The anterior approach of carpal antelunar fracture-dislocation was recently honored. This approach offers the benefit of better control of associated intracarpal fractures. In our case, the fracture of the capitatum forced us to a dorsal approach. This approach allowed the reduction and osteosynthesis of the scaphoid satisfactorily. At 3 months, the patient has very good clinical and radiological results.
