Internal Medicine is a distinct branch of specialty veterinary care encompassing infectious disease and disease prevention, neurology, neonatal and geriatric medicine, as well as respiratory, ophthalmic and cardiac disease. In other words, Internal Medicine encompasses not just the internal organs, but also many "odd and obscure" conditions. Although most equine veterinarians practice some internal medicine each day, specialization in this discipline can allow a better in-depth assessment of many diseases or processes.

All surgeries at Montana Equine are performed under advanced anesthetic care. In addition to supporting ventilation and blood pressure, surgery patients are carefully monitored to minimize risk. Analysis of patient blood-gasses is routinely performed during anesthesia, helping our doctors better monitor your horses' metabolism, and therefore improving patient outcomes. Digital radiographs can be viewed in the surgical suite to guide treatment during orthopedic surgery. Minimally-invasive surgeries, such as standing laparoscopic ovariectomy, are also performed by our team. Following surgery, each horse is assisted by at least two people during the recovery process. And beyond the standard supported-recovery from general anesthesia, a sling apparatus is also available to assist recovery during orthopedic and other severe cases.

At Montana Equine, we focus much of our time on lameness diagnosis and treatment. All of our doctors are well-versed in the details of advanced lameness diagnosis and treatment. Lameness can result from any number of sources, including not just joint disease, but also conformational abnormalities, inflammation in tendons (tendonitis) and ligaments (desmitis), bone injuries, muscle pain and developmental bone abnormalities (OCD). We always recommend a detailed, methodical approach to effectively localize the exact source of your horse's lameness. Brief exams may also be indicated under certain circumstances and are always offered upon request.
As part of the complete lameness exam, the veterinarians at Montana Equine will take a detailed medical and athletic history of your horse and will perform a thorough visual appraisal of the horse at rest. We will examine your horse for conformational abnormalities, palpate all pertinent musculoskeletal structures for pain, heat or swelling, and evaluate the gait under varying conditions and after joint flexion tests. This evaluation process directs the diagnostic tests we choose to perform, which may include nerve blocks (to regionalize the source of lameness) or ultrasound and radiographs, which help identify the specific causes of lameness.
Lameness cannot be effectively treated without a specific diagnosis. While some sources of lameness, such as foot abscesses and hock arthritis (spavin), are common and more easily diagnosed, lameness resulting from soft tissue injuries can be subtle and manifest as poor performance or reluctance to perform specific movements.
Our specialist veterinarians' all have advanced training in diagnosis and treatment of musculoskeletal injuries and disease. Their thorough approach informed by the most recent research and utilizing the most current techniques to help formulate a plan for returning your horse to its intended use and performance level.
