  • If the results of the Whole Horse Exam (WHE) suggest the horse is otherwise normal.
  • If the lameness is mild.

Lameness is an alteration in gait caused by pain or a restriction on movement (mechanical lameness).

Recently observed hind limb lameness may be caused by a simple problem that will resolve on its own or by a more severe condition that requires veterinary care. Since there are hundreds of potential causes, it is very difficult to discern the difference between a minor self-resolving problem or a major problem.

The most common locations for hind limb lameness are the foot and the hock. As with the front limb, hoof bruises and abscesses are always high on the list.

WHAT TO DO

Assess your horse’s general health using the Whole Horse Exam (WHE), paying particular attention to the presence and severity of lameness at the walk. Take their rectal temperature.

Look carefully for swelling in the limb and carefully assess for digital pulse and heat in the lower limb and foot. Compare the apparently lame limb to the other limbs. Check the sole carefully for packed debris, penetrating nail or other injury. Share your findings and concerns with your vet.

WHAT YOUR VET DOES

Your vet will assess the horse’s general health, and perform a lameness exam. At that point, further diagnostics can be considered.

Note, when it comes to lameness, (particularly in the hind limb) it is very difficult for a vet to determine whether the underlying problem is simple or complex without examining the horse. Hind limb lameness exams can range from quick and simple to grueling and expensive.

What Not To Do

Do not treat your horse yourself with an NSAID (bute), without involving your vet. You risk encouraging your horse to use a damaged limb or allowing a disease process to worsen. Continuing to work a lame horse can lead to chronic lameness in the future.
