Another name for Navicular disease in horses is Navicular syndrome. It leads to the degeneration or inflammation of the navicular bone as well as its surrounding tissues usually in the facade feet of the horse. The navicular disease can cause significant lameness of a horse. The navicular bone is situated between the deep digital flexor tendon and the pedal bone. With an infected hoof, one can notice contracted width of the foot, necrotic appearance or tendon tears, and chronic inflammation of the section surrounding the navicular bone. This sickness is supposed to be genetic, but it can occur as a result of the conformation of the distal limbs. Structure linked with Navicular disease includes under-run heel, a ‘broken back’ hoof-pastern axis, and excessively long toes. It’s more frequent in maturing riding horses and is linked more commonly with particular breeds, for example, Quarter horses, thoroughbreds, and warmbloods.
Damage to the navicular bone could happen due to disturbance to the navicular bone or limited blood supply. Lameness and pain can as well occur in the navicular ligaments, navicular bursa, and flexor tendon. Generally, when a horse suffers from Navicular disease, they show symptoms through low-grade bilateral lameness. There is also the symptom of head-bobbing, more so at the trot. The navicular disease progresses slowly and lameness might only be noticed from time to time. Another way through which to determine whether a horse is suffering from Navicular disease is nerve blocks. Nerve blocks refer to the insertion of a local anesthetic in the region of the nerves on the backside half of the foot that borders the navicular bone. After the anesthetic is applied, lameness gets better. Blocking the coffin joint might also better lameness in horses that have Navicular disease.
Veterinarians have shown the worsening of the vascular bone using radiograph footage. However, using radiographs is much debated when determining this disease as some horses might not exhibit any symptoms on a radiograph. More lately, magnetic resonance imagining is utilized to find Navicular disease. When considering treatments, it is crucial to recall that Navicular disease is degenerative and thus not curable. Many methods are meant to assist the horse experience less sting while being worked. Phenylbutazone is an anti-inflammatory and pain reducer that’s utilized for short periods. Nonetheless, more permanent solutions are also available. The most effective method is proper shoeing meant for navicular problems. It is important that the hooves of a horse are balanced as well as level on the ground. Broken-forward and broken-back pastern angles contracted heels, and under-run can be corrected. Generally, an egg bar shoe enhances heel support. Shock-back wedges and pads are utilized with shoes to elevate the heel and eradicate direct weight on the navicular bone. Insertion of the coffin joint with steroids has bettered soundness in about a third of horses suffering from Navicular disease. Another alternative is the most permanent and most invasive is performing a palmar digital neurectomy. It relieves the entire pain plus prolongs the worth of a horse. To prevent Navicular disease, heel support, maintaining a balanced foot, and exercising your horse on the floor with sound footing are recommended.
