About

Dean W. Richardson is a leading equine surgeon and researcher whose work centers on advanced diagnostic imaging, particularly standing cone beam computed tomography (CT), to prevent catastrophic musculoskeletal injuries in racehorses. His major contributions lie in validating this technology for early detection of subchondral bone pathology in the fetlock joints of Thoroughbreds—a critical step before irreversible damage or bone failure occurs. His landmark 2020 study, cited 35 times, demonstrated the reliability of standing cone beam CT for diagnosing subchondral fetlock lesions, establishing a new standard for non-invasive, weight-bearing imaging. Richardson’s 2024 prospective study, with 15 citations, further advanced the field by tracking bone morphology changes in 2-year-old horses during their first year of training, offering unprecedented insights into stress-induced injury progression. Beyond imaging, he has pioneered standing arthroscopic techniques, as shown in his 2020 case report on treating temporomandibular joint sepsis in a horse—a minimally invasive approach that reduces anesthetic risks. With a career spanning decades at the University of Pennsylvania’s New Bolton Center, Richardson’s work has profoundly impacted equine welfare and racing safety, making him a pivotal figure in veterinary orthopedics.
