  • 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).

Sudden onset forelimb lameness is a very common equine emergency. About 90% of forelimb lameness arises from a problem in the lower limb, below the fetlock joint. Upper front limb (shoulder, elbow) lameness is generally very rare in adult horses.

There are as many potential causes as there are anatomic locations within the limb. The most likely diagnoses depends very much upon the horse’s breed, type, conformation and use.

Conditions causing lameness can involve any of the tissues of the limb: skin, hoof, connective tissue, muscle, bone, joint, ligament and tendon, tendon sheath, bursa, nerves and blood vessels.

Often acute or sudden forelimb lameness is assumed to have recently occurred, but may simply have gone undetected.

WHAT TO DO

Assess your horse’s general health using the Whole Horse Exam (WHE). Take a rectal temperature. Look for swelling anywhere on the lame limb. Lift the hoof and inspect the solar surface of the hoof for stones or other objects. Feel for digital pulse. Compare your findings on the lame limb with those of the normal limb. Look for signs of other abnormalities or problems.

Contact your vet with your findings and concerns.

WHAT YOUR VET DOES

Your vet takes a careful history and performs a physical and lameness exam. Identifying the underlying problem is essential to the choice of treatment.
