![]() Scaphoid fractures usually occur as a result of a fall on the outstretched hand 4. Predominantly, scaphoid fractures happen in adolescents or older children. <10 years) to sustain scaphoid fractures. Scaphoid fractures are easily the most common fracture of the carpal bones. How common are they and how do they occur? How are they classified?īy location: Proximal third, Middle third, Distal third, articular surface or tubercleīy orientation: transverse, vertical or obliqueĭisplaced or non-displaced 3. Whilst immobilisation of scaphoid fractures has traditionally been in a thumb spica, there is good evidence to show that immobilisation of the wrist alone in a short-arm cast is just as effective in promoting union and preventing avascular necrosis. Mismanaged fractures can cause malunion and necrosis to the proximal end of the bone and in turn cause instability of the wrist joint. As such, fractures to this area or more proximally can cause poor outcomes if not managed appropriately. Approximately 75% of the arterial supply is from branches of the radial artery through vascular perforations on the dorsal surface near the tubercle and waist.Īs vascular supply to the proximal pole is mainly retrograde, a fracture through the waist places the proximal pole at risk of avascular necrosis. Scaphoid fractures are much more common in adolescents than younger children. The scaphoid begins ossification around the 4th year of age and may be earlier in females than males. The Scaphoid bone is one of 8 carpal bones in the wrist.
