The study of arterial supply of the carpal joint in one-humped camel (Camelus dromedrus)

BACKGROUND: There is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. In order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. OBJECTIVES: This study aims at describing the origins, arrangements, and branches of the arterial supply of the carpal joint of the adult one-humped camel (Camelus dromedarius). METHODS: Twelve left forelimbs of camelus Dromedrus without any lameness history were divided into 3 equal groups randomly. The brachial artery, before the elbow joint, was injected with warm water containing red gelatin, red latex solution, and rodopas resin solution separately; then, the arterial supply of the carpal joint was studied. RESULTS: The results showed that the radial, median, and caudal interosseous arteries and their branches supplied the carpal joint. (Supplied the carpal joint) CONCLUSIONS: Our findings showed that radial artery and its branches such as dorsal and palmar carpal branches were the most important arteries that supply the carpal joint. Median and caudal interosseous arteries support supplying this joint too but the arterial branches supplying the carpal joint in the Bactrian camel are from the radial artery and dorsal interosseous antebrachium branches. In the cow, the common interosseous, median, collateral ulnar and radial arteries give off branches to supply the carpal joint while common interosseous, median,transverse cubital and radial arteries give off branches to supply the this joint in the horse
