"Die-punch fractures result from an axial loading force 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 used in the tool-and-die trade. The die-punch mechanism classically involves the lunate fossa of the radius but can occur from any loading injury 2."
"Outcomes depend on restoration of articular congruity; residual step‑off, loss of reduction of the lunate facet fragment, and malunion are associated with pain, stiffness, and radiocarpal arthrosis 5."
