Colles' Fracture

(Fracture, Distal Radius; Distal Radius Fracture; Transverse Wrist Fracture; Dinner-Fork Deformity of the Wrist)


A Colle's fracture is a break in the distal part of the radius bone. The radius is one of the bones of the forearm. The distal end of the bone is considered part of the wrist. Distal radius fractures are categorized by type:
  • Open fracture—a broken bone that breaks through the skin
  • Comminuted fracture—a bone that breaks into more than two pieces
  • Intra-articular fracture—a broken bone within a joint
  • Extra-articular fracture—a broken bone that does not involve the joint
