scaphoid bone

scaphoid bone

a (tarsal) bone in the foot and a (carpal) bone in the wrist. Latter is commonly damaged by compression, causing scaphoid fracture, when there is a fall onto the outstretched hand in hyperextension. If the fracture involves the proximal third of the scaphoid, there is a high risk of non-union and threat of avascular necrosis, due to the poor blood supply.
