<prompt> Scaphoid fracture which area has maximum chances of Avascular Necrosis?Proximal 13Middle 13Distal 13Scaphoid Tubercle Fracture  <response>: a Proximal 13 Most of the blood supply to the scaphoid enters distally, so blood supply of scaphoid diminishes proximally. This accounts for the fact that 1 of distal third, 20 of middle third, 40 of proximal third and 100 of proximal pole fractures result in avascular necrosis or non-union of the proximal fragment.Scaphoid blood supplyAVN scaphoid
