| Abstract: | The arterial supply of human first metacarpal bone and carpal trapezium was studied in 166 specimens by perfusing and clearing techniques. The nutrient artery to the first metacarpal bone originates from the princeps pollicis artery and pierces the shaft palmarly in the middle third of the bone. The epiphyseal and metaphyseal arteries to the first metacarpal bone stretch from the proximal and distal arterial rings which situate at the proximal and distal ends of the bone respectively. The arterial supply of the trapezium mainly run from the radial artery and its superficial palmar branch to enter the bone through the dorsal, radial and palmar sides. Their clinical significance has been discussed based on the results obtained. |
