bayer ad hunthorseYou can’t deny the beauty of a horse working at peak performance. That’s why lameness – an alteration in a horse’s gait – is a symptom to be wary of. Not only can it affect the gracefulness of your horse’s stride, but lameness can also be a sign of joint trauma.

Signs of lameness
Lameness is measured on a scale of 0 (imperceptible under any circumstances) to 5 (the horse is almost completely unable to move).1

If you notice a difference in performance or disposition, it might be time to contact your veterinarian for a professional evaluation. The examination will include a variety of tests including joint flexion, visual appraisal of the horse at rest and under saddle, plus applying hoof testers to the hooves, and palpation of the tendons and ligaments to check for swelling or sensitivity.

Bigger dangers ahead: synovitis

If the initial examination shows signs of joint trauma, your veterinarian may begin diagnostic tests for onset joint diseases like synovitis, which causes an inflammation of the fluid-producing membrane inside the horse’s joint. By-products of severe inflammation include damaged cartilage in joints and the creation of adhesions (bands of scar tissue further restricting movement).

Back on track with Legend® (hyaluronate sodium) Injectable Solution
If your horse is suffering from synovitis, treat him fast. Using a hyaluronic acid (HA) treatment like Legend® (hyaluronate sodium) Injectable Solution can help reduce joint inflammation and put your horse on the path to recovery.

Legend® is the only FDA-approved joint therapy labeled for Intravenous (I.V.) AND Intra-articular (I.A.) treatment of joint dysfunction of the carpus and fetlock due to noninfectious synovitis associated with osteoarthritis.

Aside from its 20 years of treatment success, Legend® is backed by Bayer research and independent university studies.2 One study demonstrated that three doses of Legend® given intravenously reduced joint inflammation and its associated pain and lameness by decreasing the inflammatory mediators. These mediators of inflammation (prostaglandin and total protein levels) remained decreased 45 days past the last I.V. injection indicating a prolonged beneficial effect.3

Treating your horse with Legend® is also simple. An I.V. injection can be given once a week for three weeks and results in treatment of all indicated joints of the horse.

Being aware of your horse’s gait and staying ahead of any joint trauma is a major step in preventing long-term health issues. In the event that there is joint dysfunction due to synovitis, it’s good to know that it can be treated effectively with the proven efficacy of Legend®.
