The scaphoid (also known as the carpal navicular) is perhaps the most important of the eight carpal bones. The scaphoid links the carpal bones closest to the radius and ulna, the so-called the “proximal row,” to those articulating with the metacarpals, the “distal row.” Owing to its tenuous blood supply, the scaphoid is particularly susceptible to osteonecrosis (and ensuing post-traumatic arthrosis) after fracture. Unfortunately, the scaphoid is also the most commonly fractured of the eight carpal bones (Figure 1). Fracture is usually caused by a fall on an outstretched hand (a mechanism also associated with distal radius fractures and radial head fractures).
