Osteochondroma: A Kind Growth until It Becomes Painful

An osteochondroma is a non-cancerous growth that develops during childhood or teen years. The abnormality appears on the bone’s surface near the developing cartilage tissue of the bone ends. The growth is comprised of both bone and cartilage tissue. The tumor may continue to enlarge as the individual grows, but once the skeletal system is matured and the bones solidify, the tumor stops growing. Osteochondroma may grow as a solitary tumor or many tumors, which is called osteochondromatosis. However, solitary growths are more prevalent than multiples.

In many instances, no treatment is needed. But when osteochondroma occurs in the foot, they are apt to be painful due to the concentration of bones and supporting tissues. It can be painful especially when bumped or when in a location where shoes apply pressure to the growth.

Little is understood about the causes of osteochondroma. They are not injury related and seem to affect males and females in near equal numbers. Doctors have no way of preventing them at this time. Osteochondroma may grow out from the bone with a stem-like base, called pedunculated. If the tumor grows closer to the bone with a wider base it is referred to as sessile.

Symptoms of solitary osteochondroma include:

• A bump that protrudes near a joint
• Pain with activity or pressure on the growth
• Numbness or tingling if the growth puts pressure on a nerve

If your tumor causes you pain or disability due to nerve pressure and you seek treatment, you will have to undergo imaging tests such as X-rays, CT scan, or MRI.  These tests will allow your doctor a complete view of the growth and a better understanding of how to treat your foot. Many times, no treatment is necessary unless the pain prevents normal activity, but the growth should be monitored for change. If you do require surgery, you should discuss with your doctor the possibility of recurrence. Osteochondromas are common and tend to recur with great frequency.

If you have a growth that appears on the top or side of your foot near a joint, contact Dr. Bowman at (713) 467-8886. He can conduct a thorough examination of your foot and order the necessary imaging to complete your diagnosis. He will discuss your options and get you started on a treatment plan to lessen your discomfort and speed you on your way to better foot health.
