ABSTRACT
NOMENCLATURE (Fig. 64-3) n Colles’ fracture: Distal radius fracture with dorsal comminution, angulation, displacement, and
radial shortening n Smith’s fracture: Known as reverse Colles’ fracture because it contains a volarly displaced
distal fracture fragment n Barton’s fracture: Unstable, displaced articular fracture−subluxation of the distal radius with
displacement of the carpus and articular fracture fragment n Die punch or lunate load fracture: Depression fracture within the dorsal aspect of the lunate fossa n Chauffeur’s fracture: Intraarticular fracture that includes the radial styloid process, which is
displaced along with the carpus
