Wrist and Hand Trauma
A 45-year-old male presents following a fall onto his outstretched hand from a ladder. He reports wrist pain and swelling. Plain radiographs show a distal radius fracture with minimal displacement on AP view, but lateral view reveals concerning dorsal angulation. CT scan demonstrates a lunate facet depression fracture with 4mm of articular step-off and a separate volar lunate facet fragment. The fragment involves 40% of the articular surface. Three-dimensional reconstruction confirms a die-punch fracture pattern requiring operative intervention. Regarding die-punch fractures:
