Splints
Symptoms
Bony swellings on the cannon bone usually on the front legs. Lameness may be seen depending on the area the splint is developing and is more pronounced after exercise. Most often seen in young horses. Heat and pain when touched may be seen whilst they are developing, becoming hard and painless in the later stages, with some of the swelling receding. Lameness may continue if the growth affects the knee or ligaments, although this happens rarely.
Cause
Continuous strain on the legs whilst the bone and ligaments are immature. New bone is formed to help strengthen the legs in areas where it is needed. They usually occur in older horses when their workload changes suddenly.
Treatment
Complete rest should be given. Corticosteroids can be administered to prevent bone growth and reduce inflammation. Correct diagnosis should be given in case there is a fracture caused by an injury which will need treating differently. Young horses should not be overworked and any changes to the workload should be gradual. Over time the splint will usually mature and be just a cosmetic flaw, although this will affect showing potential. Surgery is possible, although the scar may still be evident.
