In canines the carpal bones form a complicated set of articulations and comprise of two rows; proximal and distal. In total there are seven carpal bones. Starting medially, the proximal row consists of the ''radial and intermediate'' bone (which are seperate in other species but fused in canines), the ''ulna'' bone and the ''accessory'' carpal bone. The accessory bone is essentially a bony appendage on the lateral aspect of the carpus and can be easily palpated. Each of the proximal carpal bones articulates proximally with the radius and ulna and distally with the intercarpal joints (between the proximal and distal carpal bones). | In canines the carpal bones form a complicated set of articulations and comprise of two rows; proximal and distal.
