An unusual fracture of the scaphoid

A case of unusual displacement of the proximal pole of an acute scaphoid fracture is presented. The usual mechanism of scaphoid fracture, dorsiflexion of the wrist, probably did not pertain in this case. We believe that a palmar hyperflexion injury to the wrist drove the proximal pole through the dorsal capsule. On extension of the wrist, the dorsal lip of the radius sheared off the proximal pole.
