total of 55 branches were distributed in the radial side of the second dorsal metacarpal artery and 48 branches were distributed in the ulnar side. There were seven more branches in the radial side than in the ulnar side. The mean diameter of the radial branches was smaller than that of the ulnar cutaneous branches;however, there was no significant difference in the distribution of the diameter of the cutaneous branches in the radial and ulnar sides (p = 0.659). The mean pedicle length of the radial branches was significantly less than that of the ulnar branches (p = 0.265).Therefore, there was no significant difference in the distribution of the diameters and pedicle lengths of the cutaneous branches in the radial and ulnar side (Table 2 and Figure 3).
