A retrospective study of carpal radiographs from 42 racing thoroughbreds with carpal lameness was performed. Radiographs from 50 carpal examinations were available for review. The radiographic findings pertaining to the third carpal bone were described. Fractures and/or sclerosis occurred almost exclusively within the radial fossa. The occurrence of sclerosis without fracture in 20 of the 50 carpal examinations was higher than anticipated, occurring in both the right and left third carpal bone with equal frequency. The right third carpal bone was more frequently fractured and more severely affected than the left. The sclerotic changes seen in the radial fossa of the third carpal bone may be stress‐induced, possibly preceding more serious changes in the joint such as cartilage damage or gross fracture. Earlier recognition of sclerosis of the third carpal bone may help prevent more serious changes from occurring.
