SUMMARY: The current study has been achieved to be an essential resource for all veterinary practitioners that deal with the anatomy of the carpal joint of the donkey. Ten adult donkeys of both sexes were used in the current study. The topographical approach to the carpal joint was investigated in this study. Radiography and

The carpal ligaments were well delineated and the carpal canal was demonstrated with its content such as superficial digital flexor tendon (SDFT) and deep digital flexor tendon (DDFT). The contrast radiography visualized that the radiocarpal joint outpouched proximal to the accessory carpal bone by large palmarolateral pouch and small palmaromedial pouch, however the intercarpal joint outpouched distal to the accessory carpal bone by two small palmarolateral and palmaromedial pouches. The carpometacarpal joint showed medial and lateral palmarodistal outpouchings in distal direction between the corresponding 2nd and 4th metacarpal bones and the 3rd metacarpal bone. Scanning electron microscopy (SEM) displayed two types of synoviocytes macrophages type A cells and fibroblast like type B cells at the cellular lining of the synovial membrane of the joint capsule.
