Scaphoid Fracture
A scaphoid fracture describes an injury that breaks the scaphoid bone in the wrist.
The wrist joint is formed by the articulation of the radius and ulna bones of the forearm with three of the eight carpal bones at the base of the hand. These carpal bones are arranged in two rows, one nearer the hand and one nearer the forearm. The boat-shaped scaphoid bone links the two rows and is particularly vulnerable to injury. It is in fact the most commonly broken carpal bone in the wrist. It is found is on the thumb side of the wrist and articulates with the distal end of the radius, helping to limit the degree of movement of the wrist.
