Second metacarpal Trapezoid bone In order to evaluate the carpal-metacarpal joint of the thumb, the median nerve must be deadened at the wrist (causing paralysis of the muscles supplied by it distal to the injection) to test the joint. The palmar metacarpal arteries terminate at finger clefts by joining the common digital branches of the superficial palmer arch. ; Recurrent branches run proximally facing carpus towards end inside the … artery at the bony apex of first web space where it passes deep to first dorsal interosseous muscle to enter the palmar space. The PPA is typically one of the terminal branches of the radial artery. The dorsal metacarpal arteries have vascular connections with the dorsal, and superficial arch, as well as the common palmar digital arteries [9]. If the knuckle of the third metacarpal head is level with the knuckles of the second and fourth metacarpal heads, the sign is positive and indicative of a lunate dislocation. The artery's pulse is palpable in the anatomical snuff box and on the anterior aspect of the arm over the carpal bones (where it is commonly used to assess the heart rate and cardiac rhythm).
