## Overview Subchondral bone sclerosis is increased density of the bone beneath the joint cartilage from repetitive loading. It is a response to stress and can precede more serious injury such as fracture or osteoarthritis. It is seen on radiographs or computed tomography in performance horses, especially racehorses. ## Causes Repetitive high-load exercise. ## Diagnosis Imaging showing increased bone density. ## Treatment Modification of training to allow bone remodeling. Rest if associated with lameness. ## Recovery and Prognosis Good if workload is adjusted before catastrophic injury. ## Prevention Appropriate training progression.
often subclinical; may contribute to lameness; increased bone density on imaging; seen in high-level performance horses
