Areas of nerve injury or demyelination appear as slowing of conduction velocity along the nerve segment in question. The wrist is comprised of the carpus and the radiocarpal joint.The carpus is the complex of eight carpal bones (scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate), while the radiocarpal joint is the region of articulation between the carpus and radius. Risk factors include a superficial position, a long course through an area at high risk of trauma, and a narrow path through a bony canal. For nonunions, your doctor may use a special kind of graft with its own blood supply (vascularized graft).

If you poke around the snuff box you can feel both the scaphoid and the trapezium as well as the radial artery. When refering to evidence in academic writing, you should always try to reference the primary (original) source.
