<prompt> True about blood supply of scaphoid-Mainly through ulnar arteryMajor supply from ventral surfaceMajor supply from dorsal surfaceProximal supply in antegrade fashion  <response>: Ans. is c i.e., Major supply from dorsal surfaceo Major blood supply 70-80 of scaphoid comes through dorsal surface via dorsal branches of radial artery,o These dorsal vessels enter the scaphoid at or just distal to waist area and supply the proximal pole in retrograde fashion.o Proximal 23 rd to 34 scaphoid is supplied by these dorsal vesselso 20-30 of blood supply comes through palmar and superficial palmar branches of radial artery,o Distal 13 rd or 14 th and distal tubercle are supplied by these palmar vessels.
