Observations on the intraarticular use of corticosteroids in the racing thoroughbred

A project to determine if intraarticular corticosteroid therapy was deleterious to the racing Thoroughbred was carried out in the 1971, 1972, and 1973 racing seasons. Of 22 horses available for follow-up examination, 6 had radiographic evidence of deterioration; 1 of these was destroyed because of probable corticosteroid-induced arthropathy. The remaining 16 horses did not have any evidence of deterioration. One of the 16, a stakes winner, had been given 12 injections into the left front fetlock during the 3-year period. It was concluded that if proper and careful aftercare is adhered to, intraarticular injections of corticosteroids can be carried out with relative impunity.
