The third to fifth metacarpals are dorsally dislocated from their articulations with the capitate and hamate. Alignment of the second metacarpal with the trapezoid and the first metacarpal with the trapezium is normal. There are fractures through the base of the third and fifth metacarpal bones. There is a fracture through the dorsal surface of the hamate, as well as a likely fracture through the dorsal surface of the capitate. There are multiple small fracture fragments that lie adjacent to the bases of the third to fifth metacarpals, most numerous around the base of the third metacarpal.
Allowing for slight dorsi flexion at the wrist, alignment of the carpal bones is within normal limits. No distal radius or ulnar fracture. Volar plaster in situ.
