Identification of an ossicle associated with the palmar aspect of the carpus in the horse

Abstract

An ossicle associated with the palmar aspect of the carpus is described in five horses. The size of the ossicle varied from 3 × 4 mm to approximately 12 × 10 mm. The ossicles were located at the junction of the proximal and distal rows of carpal bones, between the palmaromedial aspect of the fourth carpal bone and the ulnar carpal bone. In 3 horses they were bilateral, in one horse unilateral, and only one limb was examined in the remaining horse. In all horses it was an incidental finding and not regarded to be a pathologic entity.
