In comparison to Thoroughbreds, little epidemiological research has been conducted in Quarter Horse racing [21–23]. All of the information comes from the work conducted through the CHRB Post‐mortem Program. Even though full post‐mortems were conducted, the predominant fracture site was described as the fetlock (0.76 per 1000 starts) followed by the carpus (0.48 per 1000 starts), vertebra (0.14 per 1000 starts) and scapula (0.13 per 1000 starts) [21]. The work demonstrates some clear differences in fractures resulting in euthanasia from Thoroughbreds: fractures of the Mc/Mt3 condyles and humerus are more common in Thoroughbreds, whereas carpal, vertebral (particularly lumbar) and scapula fractures are more common in Quarter Horses [22, 23]. The authors hypothesized that differences may be due to inherent breed characteristics such as conformation or limb geometry affecting locomotor biomechanics and, as they compete in races of very different distances, there are also consequent differences in speed.
