The length of snuffbox segment of radial artery was 2.60±0.13cm, in which the outer diameter of proximal and distal ends was 2.65±0.17mm and 2.2±0.21mm respectively. A measurment was also made on the level of origin of the dorsal carpal branch and dorsal thumb branch of this segment radial artery. The surface projection of this segment radial artery was a line drawing from the middle point between the dorsal tubercle of radius and the head of the first metacarpal bone to the middle point between the lower end of the styloid process of radius and the base of the first metacarpal bone.
