Abstract
The prevalence of carpal fractures was determined for 211 Thoroughbred and 75 Standardbred racehorses. Statistically significant differences were found in the location of fractures between the 2 breeds. In the Thoroughbred and Standardbred groups, total fractures (460) were distributed nearly equally between the left (224) and right (236) carpi. The most common site of fracture in the Thoroughbred group was the distal aspect of the radiocarpal bone (112), whereas the most common site of fracture in Standardbred horses was the proximal surface of the third carpal bone (61). Slab fractures were more common in the right carpus of Thoroughbred horses (29 right/11 left), but were distributed equally between the left (11) and right (11) carpi of the Standardbred group. Fractures of the distal border of the radius and intermediate carpal bone were more common in the left carpi of the Thoroughbred group and were relatively uncommon among Standardbred horses. Fractures within the intercarpal joints (313) were more common than those within the radiocarpal joints (147) in Thoroughbred and Standardbred horses.
