A die-punch fracture results from axial loading forces on the distal radius. It is an intra-articular fracture of the lunate fossa of the distal radius ¹. It is by definition depressed or impacted and is named after the machining technique of shearing a shape, depression or hole in a material with a die implement or cutter. The die-punch mechanism classically involves the lunate fossa of the radius but can occur from any loading injury ².
