The blood supply of the scaphoid bone.

Scaphoid vascularisation was investigated using macroscopic and microscopic techniques in 12 uninjured, formalin fixed cadaver hands. A good blood supply of the scaphoid bone from palmar, dorsal and radial vessel groups with a variety of anastomoses was found which should provide sufficient collateral blood flow from adjacent regions in some patients. Since blood supply is available from the palmar circulation, a dorsal approach to the scaphoid bone is possible.
