Anatomy 101: Wrist Bones


The wrist bones and hand bones give you the support and flexibility needed to move your hand in all different ways and control objects of all shapes and sizes. There are eight bones in the wrist:

  1. Scaphoid
  2. Lunate
  3. Triquetrum
  4. Trapezoid
  5. Trapezium
  6. Capitate
  7. Hamate

The scaphoid bone is the most commonly injured wrist bone, typically resulting in a scaphoid fracture.
