Wrist X-rays - position of the scaphoid (S) bone within the wrist joint

Scaphoid fractures are often not obvious early and only become visible later, usually on repeated X-rays 1 -2 weeks later

Scaphoid fracture can be associated with unfavourable loss of vascularity (avascular necrosis) to one of its fragments; MRI is required to delineate this as demonstrated on the right picure: marked colour discrepancy between two fragments; black part of broken scaphoid on this image confirms avascular necrosis

Special compression screw is used in surgical fixation of two scaphoid fragments to improve chances of their healing (union)
