Thirty‐five carpal joints from 20 standardbred trotters, age 1 to 7 years, all euthanized for nonorthopedic reasons, were examined to investigate the correlation between assessments of subchondral bone sclerosis in the third carpal bone from radiographs in the dorsoproximal‐dorsodistal (DPr‐DDi) projection and histomorphometric bone volume density measurements. The agreement between assessments of sclerosis from antemortem versus postmortem radiographs was also evaluated. Bones graded as sclerotic in the DPr‐DDi projection had significantly higher bone volume density values for all areas of measurement than nonsclerotic bones. For sclerotic bones, grading of sclerosis was significantly associated with volume density measurements in the central cancellous bone only. There was a good agreement ( k w =0.71) between assessments of radiographic bone sclerosis from antemortem versus postmortem radiographs.
