Osteochondroma

Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. It usually grows as the child grows and stops when the child reaches skeletal maturity. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade.

Osteochondroma is the most common noncancerous bone growth. It most often occurs between ages 10 and 30.

While the exact cause of osteochondroma is not known, there is one type that is inherited and one type that isn't inherited.

These are the most common symptoms of osteochondroma:

• A hard growth on a bone that is painless and doesn't move
• Lower-than-normal-height for age
• A leg or arm that is longer than the other
• Pressure or irritation with activity
• Soreness of the nearby muscles or tendons
• Numbness or tingling
• Changes in blood flow

Often, people with osteochondroma will have no symptoms at all.

When they do happen, symptoms of osteochondroma may look like other health problems. Always talk with your doctor for a diagnosis.

Your doctor will review your health history and do a physical exam. Other tests include:

• X-ray. This test uses invisible electromagnetic energy beams to make images of tissues, bones, and organs.
• CT scan. This test uses X-rays and a computer to make images of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
• MRI. This test uses large magnets, radiofrequencies, and a computer to make detailed images of organs and structures in the body.

Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.

Treatment for osteochondroma varies depending on the size of the growth and your symptoms. Treatment may include:

• Surgery to remove the growth
• Medicines to control pain

If there is no sign of a bone getting weak or increased overgrowth, your doctor may want to watch it over time. Careful follow-up with a doctor to keep track of bone growth may be advised.
