It is used as a salvaging procedure to save the horse with an injury that disrupts the stability of a joint, such as septic arthritis, failure of the suspensory apparatus, subluxation, fracture, or collateral ligament rupture, or may be used to treat chronic osteoarthritis. It is most commonly used to treat disease of the coffin, fetlock ...
For example, racehorses are more likely to have fatigue-related injuries such as stress fractures and injury to the flexor tendons, while western show horses are more likely to have navicular syndrome and English sport horses are more likely to have osteoarthritis or injury to the suspensory ligament.

A draft horse sleeping while standing up. The stay apparatus is an arrangement of muscles, tendons, and ligaments that work together so that an animal can remain standing with virtually no muscular effort. [1] It is best known as the mechanism by which horses can enter a light sleep while still standing up. [2]
Proximal check ligament desmotomy has been shown to return horses to work faster, but is thought by some to predispose to suspensory ligament injury. [citation needed] Mesenchymal stem cells, derived from the affected horse's bone marrow or fat are currently being used as a potential therapy for SDFT tendinitis and other injuries. [11] [12]
The main purpose of the suspensory is to support the fetlock joint, preventing it from overextending. Injury to this ligament is an important cause of lameness in performance horses. The suspensory is a modified muscle, the equine equivalent of the interosseous muscle, which contains both tendon fibers and residual muscle fibers. [1]
As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today. Good conformation in the limbs leads to improved movement and decreased likelihood of injuries. Large differences in bone structure and size can be found in ...
Male horses are overall at a higher risk of catastrophic injury than female horses, with an overall odds ratio of 1.48. This does vary by study and country, including odds ratios of 1.12 in 1.61 in Australia, 1.76 in Canada, the United Kingdom, and 1.52–2.21 in the United States. [85]
Working a horse on hard surfaces increases the concussion received by the interosseous ligament, which causes tearing. Splints caused by concussion are usually found on both front legs, most commonly on the inside of the leg a few inches below the knee. Overworking young or unfit horses at speed or in tight circles may cause splints. The uneven ...
