Radial artery has been used in coronary artery bypass grafting, in forearm flap surgeries and in renal dialysis by making an autogenous fistula. In present study, ninety upper limbs from 45 formalin-fixed cadavers were dissected meticulously to expose the radial artery from its origin to its termination. The morphometric parameters like distance between interepicondylar line and bifurcation of brachial artery, length of radial artery and internal diameter of radial artery at various levels were measured. In cases of usual bifurcation of brachial artery, mean distance between interepicondylar line (IEL) and bifurcation of brachial artery on right side was 3.56 cm and on left side it was 3.49 cm and the mean length of radial artery on the right side was 26.73 cm and on left side it was 26.58 cm. Average distance of high bifurcation of brachial artery above the interepicondylar line was found to be 5.1 cm on the right side and 4.9 cm on the left side. The length of radial artery from its origin to the first dorsal interosseous space in the cases of high bifurcation of brachial artery was found to be in the range of 27.0 - 46.5 cm on the right side and 28.0 – 47.0 cm on the left side. The length of radial artery from its origin to the first dorsal interosseous space in the cases of high origin of radial artery was found to be in the range of 40.0 - 45.0 cm. The mean diameter of radial artery on right side was 2.35 mm and on left side it was 2.30 mm.
