As adaptation to the biomechanical rigors of training and racing, some degree of bone changes, such as sclerosis, are anticipated in equine athletes. Understanding the equine joint surface and subchondral bone's imaging characteristics would enable earlier detection of injuries or modification, as well as improved prognosis and training programs. This research was intended to describe the third metacarpal bone's joint surface structural characteristics and periarticular structures. The lateral condyle's microtomography scan revealed that 50% of the samples had increased trabecular thickness. Ultrasound photographs were most closely related to the histological examination in terms of sensitivity, according to a comparison of both imaging studies, although macroscopic and radiographic examinations varied most between evaluators. The irregularities and changes found in the articular cartilage surface and subchondral bone, for example, were typical adaptations of the anatomical architectures of trained racehorses, which should be considered during clinical examination.
