Boxer's fracture is a common name for a fracture of the long bone that connects the little finger to the wrist.

The types of boxer's fractures are:

  • Nondisplaced—the bone is broken, but remains in place
  • Displaced—ends of the bone are separated from one another
  • Comminuted—the bone is broken into several pieces

Fractures may either be:

  • Closed—the fracture does not break the skin
  • Open—the fracture breaks through the skin
