HYPERTROPHIC OSTEOARTHROPATHY

General Information:

Hypertrophic osteoarthropathy is a disease that involves an increase in the thickness of the tissue immediately surrounding bone. This tissue is called the periosteum. Radiographs (x-rays) of the diseased bones show noticeable thickening, with a rough, irregular surface. Leg bones are usually involved.

Hypertrophic osteoarthropathy does not develop alone. It is caused by another disease at a different location in the body. The most common cause is a tumor or other disease of the lungs. For this reason, hypertrophic osteoarthropathy is thought of as a sign of a more serious disease.

Treatment Information:

Treatment of hypertrophic osteoarthropathy depends entirely on the success of treatment of the underlying disease; however, medication for pain may help make your pet more comfortable.
Because many cases are due to lung cancer, treatment may be of little benefit. We will advise you regarding the availability and effectiveness of treatment.
If the underlying condition is treated and cured, with time the changes in the bones should resolve.

We hope that you will find this information helpful in your quest for better pet care. If you have any questions or comments, please call your veterinarian's office, or feel free to e-mail us.
