A Unique Case of Open Radiocarpal Fracture-Dislocation Defying Classification Norms

Radiocarpal dislocation presents as loss of contact between articular surfaces of distal radius with the first carpal row at the wrist. It may be associated with fractures of dorsal or palmer rim of distal radius, radial styloid process and ulnar styloid process. These injuries are usually due to high energy trauma like the one presented here in our case report where injury occurred due to fall of tiles on the wrist. The common classifications which are used to classify these injuries are Dumontier’s and Moneim’s classification classification. Our case here could not be classified as per classifications mentioned in the literature, This case had fracture of radial styloid with dorsal lip distal radius fracture and perilunate dislocation with DRUJ dislocation associated with radiocarpal dislocation, which was defying any classification criteria. This was managed with closed reduction and percutaneous K-wires fixation and external fixation for maintaining reduction. Wound was managed with daily dressing. This case is highlighted here to create awareness about such a complicated pattern of presentation which can be managed successfully without extensive intervention.
