Abstract:
Fifty prepared specimens of adult upper extrimity were employed in the study,The arteries of each extremity were perfused with red latex and the dissection was carried out under an operating microscope.Twelve arteries participate in the formation of the arterial network around the wrist joint.It consists of 5 divisions situated in different tissue layers,3 on the dorsal and 2 on the palmar side of the extremity.The 2 divisions situated on the dorsal and palmar side of the joint capsule of the wrist respectively are the most completely constructed among the 5,and the main routes for the collateral circulation around the wrist.The dorsal division of the carpal arterial network is mainly formed by the dorsal carpal branch of the radial artery,the dorsal branch of the,anterior in- terosseus artery,and the ascending branch of the superior perforating artery,while the palmar division by the palmar carpal branch of the radial artery,the palmar branch of the anterior interosseus artery,and the dorsal carpal branch of the ulnar artery.There are extensive and multiple anastomoses between the anterior interosseus artery and the radial and ulnar arteries with a preponderance of the anastomoses over the radial side of the extremity in regard to the size and number of the participating vessels. The collateral circulation established by the anastomoses between the dorsal and palmar divisions in preponderant over the dorsal side of the extremity.The carpal arterial network is characterized by its multiple arterial origins,multiple anastomoses and multiple divisions to conform to the poly-articular construction and multi-directional movement of the wrist joint.In addition,the compensation of the blood circulation of the hand through the carpal arterial network in ease the radial artery and/or the ulnar artery are severed or gradually obliterated was discussed morphologically.
