[Interscapholunate carpal axial dislocation: a case report].
We present a case of a patient presenting a right wrist injury due to a motor vehicule accident. X-rays and CT Scan showed transcapholunate axial dislocation with the capitate impacted between the scaphoid and the lunate without perilunate dislocation. This injury was associated to a fracture of radial styloid process, trapezium, triquetrum, hamate, and a pisotriquetral and intermetacarpal dissociation. We did not find any similar case in French or English litterature. Treatment associated closed reduction and percutaneous pinning. At one year follow-up the wrist was painless with a normal range of motion. This lesion contributes to the understanding of carpal injuries mechanism. Capitate ascension within the scapholunar joint due to an important compression force is a pathogenic factor of scapholunate dissociation.
