Physitis or epiphysitis is a developmental orthopaedic disease. Physitis is most commonly a disease of heavy, fast growing foals and is often seen in both thoroughbred and sport horse herds. It is more common in foals being supplemented with large amounts of hard feed.

Physitis is most usually a disease of heavy, fast growing foals and is often seen in both thoroughbred and sport horse herds. The problem is caused by overloading or compression of the spongier growth plate part of the bone. This causes inflammation primarily but can lead to alterations in the growth of the bone, which will cause lasting damage.

Avoiding physitis is generally a case of providing a balanced diet that provides all the essential nutrients for growth without causing the foal to become overweight.

Subtle dietary deficiencies in essential vitamins and minerals are also likely to have an effect. Calcium, phosphorus, copper and zinc are understood to be the most important factors. Regular analysis of hay and grass as well as the concentrate is advised.

With early recognition of physitis and appropriate intervention the prognosis for foals with physitis is good with most mildly affected foals going on to expected sales and racing outcomes.**
