Distal Tarsal OA, Intertarsal Synovitis
Bone spavin is a bony enlargement on the lower surface of the hock joint, most commonly found on the inside or front portions. It often occurs as a result of osteoarthritis. Clinical signs may initially consist of stiffness, improving with exercise. As the condition progresses, horses often begin to show evidence of dragging of the toe of the foot, reduced performance, moderate hindlimb lameness and uneven gait. Horses with bone spavin often demonstrate a lack of power or unwillingness to engage their hindquarters, jumping horses may suddenly start to refuse jumps, and others may be worse on a particular lead or reluctant to go downhill. Lameness will usually affect both hindlimbs and will progressively get worse over time.
