A case report of coronal fractures through the hamate, the capitate, and the trapezoid.

To our knowledge, the simultaneous coronal fractures of the hamate, capitate, and trapezoid have not been previously reported in the literature. There were few reports about coronal fractures of the hamate caused only by axial loading to the ulnar column. We report 43-year-old man who presented with painful swelling on the dorso-ulnar side of the wrist after striking a wall with his right clenched fist.
