Scaphoid Non-Union Fracture


The scaphoid is one of the eight small bones in the wrist.  These small bones are arranged into two rows (Figure 1).  During normal wrist motion, the wrist bones move in concert with one another to allow the flexibility and wide variety of positions that we take for granted.  The scaphoid spans these two rows and is an important link for maintaining coordinated and stable movement of the wrist.
