Clinical Corelation of Vascularity of Scaphoid Bone

Vascularity of scaphoid has gained importance due to the cases of non union. Over the years studies of blood supply of scaphoid have been done. Three hundred scaphoids were obtained in Anatomy department of Subharti Medical College Sex and side of bone was not taken into consideration. Vascular foramina were counted on palmar and dorsal surfaces with help of loop lens and magnifying glass. Dissection of 15 fresh upper limbs was done. Polyster resin dye mixed with India ink was injected into brachial artery after which micro dissection for vasculartiy of scaphoid was done. Counting of foramina revealed that scaphoid having absence of foramina proximal to mid of waist only were at risk of non union while dissection also revealed that scaphoid has a rich collateral circulation, thus making any incidence of non union a rarity
