In this thesis 10 hands of adult cadavers (6 females and 4 males) were used. The specimens were subjected to dissection. Also 10 angiography of hands and 20 duplex ultrasound of hands were used. The arterial supply of the hands was thoroughly studied. Variations in female hands were more obvious than in the male ones and in right hands more than in left ones.According to formation, the superficial palmar arch was complete in 50%, incomplete in 35% and absent in 15%. The ulnar artery curved laterally and ended opposite the 2nd intermetacarpal space. Number of common palmar digital branches varied from two branches in 35% and three branches in 65%. There was other branches arising from the SPA as the principis pollicis in 15% and radialis indicies in 20 % and a branch to medial side of little finger in 5%.According to distribution of palmar digital arteries, palmar digital arteries supplying adjacent sides of the medial four finger. This was found in 10 hands out of 20 (50 % ). Palmar digital arteries supplying adjacent sides of the medial fingers . This was found in 3 hands out of 20 (15%). Palmar digital arteries supplying adjacent sides of middle 3 fingers. This was found in 7 hands out of 20 ( 35 % ). In the present study, we measured the diameters of ulnar, radial and SPA arteries using duplex ultrasound. It was found that the diameter of superficial palmar arch ranged from 0.99 mm to 2.8 mm with a mean value of 1.665mm. On the other hand the diameter of ulnar artery ranged from 1.6mm to 2.7mm with a mean value of 2.40 mm, while that of radial artery ranged from 1.3 mm to 3 mm with a mean value of 2.065 mm.It could be concluded from this study, that any surgical interference in the SPA would affect the vascularity of the thumb. Also, for finger transplantation and for hand transfer, full knowledge of the origin of digital branches of the arches should be known.
