Lameness in horses can be a sign of several conditions. Generally, a lame horse can’t bear weight on one of its legs. This can occur from an injury to the leg or hoof, or from a neurologic condition. Regardless of the cause, it’s important to know the signs of lameness to avoid a potential problem.
Lameness is a weight-bearing deficit
Lameness, or lack of weight-bearing capacity, is a very common problem for horses. It can be caused by a variety of problems, but most cases are treatable and the prognosis is good. A horse’s lameness can affect a single or multiple legs. There are two main types of lameness: weight-bearing lameness and non-weight-bearing lameness.
The most common sign of lameness is an altered gait, especially in the hind limb. This is often accompanied by toe drag and head nod. The problem can also be accompanied by pain in flexion of the limb. It is important to diagnose lameness as early as possible to avoid significant pain for the horse.
A veterinarian can diagnose lameness by taking a detailed history of the horse’s condition. This can help rule out breed-specific diseases, such as navicular disease or osteoarthritis. The examination can also rule out infectious or recurrent lameness.
It causes minimal weight-bearing in motion and/or at rest
When a horse is lame, he or she can’t walk, move, or run. The horse may be lame on one or more legs. It’s important to identify the cause of lameness before treating it. In most cases, lameness is not a permanent condition. However, it can get worse if left untreated. To properly diagnose lameness, it’s best to consult with a veterinarian or farrier.
The symptoms of lameness may be accompanied by pain. The source of pain can be determined using the lameness grade. The diagnosis may involve X-rays or ultrasound.
It can be caused by injuries to a leg or hoof
Horses that become lame can be due to various injuries, including injuries to the leg or hoof. This is often difficult to diagnose, but a veterinarian can use their skills and knowledge to identify the cause. A veterinarian will ask you to provide a detailed medical history, along with information on the horse’s current nutrition and exercise routine.
A vet will conduct a hands-on examination, checking the muscles, joints, tendons, and bones to detect lameness. A veterinarian may perform a flexion test, which is performed by placing sustained pressure on the affected joint for 30 seconds to 3 minutes. The veterinarian may want to do a flexion test to identify a specific source of pain for your horse. A veterinarian can also perform diagnostic tests such as X-rays, ultrasound, computed tomography, and magnetic resonance imaging to determine the cause of lameness.
It can be caused by neurologic conditions
There are several diseases affecting the central nervous system in horses. These include cervical vertebral stenosis, equine protozoal myeloencephalitis, equine herpesvirus-1 myeloencephalitis, and degenerative myeloencephalitis. The clinical diagnosis of these diseases requires a detailed history and physical examination. Diagnostic testing is also required to confirm the diagnosis, since a mild neurological condition can mimic a more severe lameness condition.
Neurologic lameness is a clinical symptom that reflects a degenerative or structural disorder of the locomotor system. It is often manifested as ataxia, and it can be caused by trauma, congenital or developmental diseases, cancers, or toxicities. The most common infectious cause is equine protozoal myeloencephalitis, though there are rarer infectious causes such as rabies or Lyme disease.
It can be treated
Lameness can be a serious problem in a horse, affecting its ability to walk or move. A thorough examination, palpation of limbs, and gait observation can help determine the cause of the lameness. Certain horses may also need joint or local nerve blocks, depending on the severity of the problem. Forelimb lameness is more common than hindlimb lameness. It generally occurs from the knee down. It can occur in the stifle or hock.
Lameness treatments can involve refitting shoes or using specialized hospital shoes for easy access by caregivers. If an infection is the cause of lameness, antibiotics, antifungal treatment, and corticosteroids may be prescribed. In more serious cases, surgery may be required.
