Keratomas are not common, usually benign and a skilled horse person may be able to identify an affected hoof as the growth causes distortions in the hoof wall and white line. Occasionally, pressure from the growth can cause necrosis of the adjacent portions of the coffin bone leading to Osteomyelitis abscessing. These keratomas may need to be removed under veterinary supervision to end the cycle of chronic osteomyelitic abscessing. For more on keratoma read Dr. A horse with an abscess is a common occurrence if one keeps horses for any length of time.
Luckily, most are treated, recovered from and back to work in under two weeks. Horses that have chronic abscessing may be helped if the causation of the infection is identified. More aggressive treatment may be necessary for horses with certain types of abscesses. Thanks for checking out my website. Please take a moment to like, share or follow and visit again soon.

After days of wet poulticing, dry poulticing is often used to avoid over-softening the foot. Poulticing will need to be continued until no further discharge is found when changing the dressing. Occasionally, it can be extremely difficult to locate an abscess despite a strong response to hoof testers, and adequate paring of the foot.
In these cases, radiography x-rays may be used to try and identify the abscess site. The signs of a foot abscess are also consistent with other conditions of the foot see list below , and radiography will help to rule them out. Although foot abscesses are a bacterial infection, antibiotics are rarely used in managing them. Firstly, the routinely available antibiotics available for use in horses do not reach the hoof in significant concentrations to be useful, and are not active against the bacteria that are commonly involved in foot abscesses.
Secondly, in cases where the abscess cannot initially be drained, antibiotic use can slow down abscess maturation and prolong the course of the disease. The provision of analgesic pain relieving drugs is another matter of opinion and debate. While it would seem that giving pain relief to a horse in obvious pain would seem obvious, this is not the case. In the initial stage of the disease, before the abscess has burst then even high doses of analgesics typically prove ineffective in relieving pain.
Once the abscess has burst, then relief from pain is extremely rapid, even without the administration of drugs. It would seem, therefore, that at no point do analgesics actually improve the pain associated with an abscess. On the other hand, the commonly used analgesic drugs also have significant anti-inflammatory effects, that can be beneficial. The decision as to whether to treat will be made on a case by case basis.
Vaccination against tetanus is vital in cases of pus-in-the-foot, and if your horse is unvaccinated, or their vaccination status is uncertain, then immediate cover will be provided using Tetanus Anti-Toxin. The prognosis for simple foot abscesses is excellent, and following drainage horses will return to soundness rapidly and totally. Once drainage is established, your veterinarian will probably apply some type of poultice or bandage to help pull the remaining exudates from the hoof.
Depending on where the abscess drains, your vet might recommend keeping the drainage site clean until it has had a chance to dry and harden. Regular hoof care and farriery is an important step in preventing hoof abscesses, but there is no guarantee that your horse will be immune to this problem. While difficult to control, avoiding extremely wet or dry conditions, as well as sudden changes in moisture, can help prevent formation of hoof abscesses.
Routine mucking of stalls, pens, or other confined areas can also help prevent them. By Brian W. Fitzgerald, DVM The scenario is all too familiar for many horse owners… yesterday your horse was sound, but today you find him crippled, with no apparent injury! Hoof Abscesses Explained Hoof abscesses occur when bacteria get trapped between the sensitive laminae the tissue layer that bonds the hoof capsule to the coffin bone and the hoof wall or sole.
Treatment The quickest way to relieve hoof abscess pain is to drain the exudates buildup, which is like popping a large pimple. As the pus pocket grows, like the water balloon, it pushes its way to the weakest point to exit. While it might seem that the weakest point would be the point of entrance, in fact, that entry point can seal up with dirt, allowing the bacteria to multiply inside and the pus pocket to grow to battle the invading bacteria.
With the entry point sealed, either enough pressure needs to build up to blow it open, or it can work its way upward through the laminae to exit through the skin at the hairline. Quite often it will grow under the sole as well.
Symptoms of a hoof abscess may include a sudden onset of lameness, often seemingly overnight, a reluctance to bear weight on that foot, and a tendency to walk on the toe. Heat in the hoof may be noticeable, along with an increased digital pulse.
In abscesses that take a longer time resolving, there might be swelling of the limb as high as the knee, painful tendons, and even fever. There are other factors involved in creating abscesses as well. Weather and environment can be big contributors. A warm, wet environment is a perfect place for bacteria to grow, as wet footing softens the structures of the hoof immensely. Any object capable of penetrating the sole — for instance, a sharp rock or a lost nail — can create the entrance point for a bacterial invasion.
A piece of sand can penetrate weakened, stressed or damaged laminae, allowing bacteria to follow. This type of infection usually results in a pus pocket that pushes its way up to find an exit at the coronet band.
A deep bruise that results in a blood pocket can become a mysterious and very painful abscess. Often the bruise is internal and not noticed. The dead coagulating blood of the bruise becomes a foreign object to the body and white blood cells are sent to attack it. With no entry point, the pressure buildup must be that much greater to create an exit.
