Osselets

Veterinary advice should be sought before applying any treatment or vaccine.

Osselets

Osselets is a common term used to describe osteoarthritis of the fetlock. It is most frequently seen in retired geriatric (older) performance horses. Osselets is usually associated with the forelimbs and often occurs bilaterally, in both forelimbs. Affected horses often present with asymmetrical lameness of an insidious onset, which gets worse when the horse is asked to make turns or following completion of exercise. These horses will often have a stiff gait and shortened stride.

The goal of therapy for horses with osselets is to relieve joint pain and help to improve joint use, lessening gait stiffness and lameness.
