Wrist Fracture Types

The wrist is made of 10 bones: 8 carpal bones and 2 forearm bones. The carpal bones include the scaphoid, lunate, trapezoid, trapezium, hamate, capitate, triquetrum, and pisiform. The forearm bones include the radius and ulna.

Structures of the wrist include:

  • Forearm, wrist and hand bones
  • Carpal bones of the wrist

Types of wrist fractures include:
  • Fractures of the radius or ulna
  • Fractures of the carpal bones

Fractures of the Radius and Ulna:
  • Colle's fracture:
    • Fracture of the radius:
    • Most common wrist fracture
    • Wrist is bent upward
  • Smith's fracture:
    • Fracture of the radius:
    • Wrist is bent downward, opposite that of a Colle's fracture
  • Chauffeur's fracture:
    • Fracture of the styloid process, part of the radius
  • Galeazzi's fracture:
    • Fracture of the radius with dislocation of the ulna
  • Monteggia's fracture:
    • Fracture of the ulna with dislocation of the radius

Fractures of the Carpal Bones:
  • Lunate dislocation:
    • Dislocation of the lunate bone
  • Lunate fracture:
    • Fracture of the lunate bone
  • Perilunate dislocation:
    • Capitate bone is dislocated from the lunate bone
  • Scaphoid fracture
    • Fracture of the scaphoid bone
  • Triquetral fracture:
    • Fracture of the triquetrum bone
