Abstract

The ulnar artery shows different patterns in hand and provides major contribution in the formation of superficial palmar arch. We have dissected twenty four hand specimens to follow the course of the ulnar artery and its branches. Classical radio-ulnar arch was observed in all hand specimens except one female cadaveric specimen where four common palmar digital arteries were arising from the convexity of the SPA instead of three as seen in classical radio-ulnar arch. The first common palmar digital artery was dividing into arteria radialis indicis and arteria princeps pollicis. The arch was completed by superficial palmar branch of radial artery. One exclusive communication was reported between radial artery proper and arteria princeps pollicis. Knowledge about arterial variations will be useful for cardiovascular surgeons, radiologists and anatomists working in this area. Occlusion of the arteries may lead to ischemia characterised by claudication, rest pain and gangrene if untreated. Therefore, anatomy of the arteries and the possibility of developing collateral circulation is of utmost importance.
