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
• 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
