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. It affects males and females equally.
While the exact cause of osteochondroma is not known. There is 1 type that is inherited and 1 type that is not inherited.
These are the most common symptoms of osteochondroma:
A hard, mass that is painless and does not 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
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 healthcare provider for a diagnosis.
Your healthcare provider will review your medical 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 of X-rays and computer technology to make images (often called slices) 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 mass
Medicines to control pain
If there is no sign of bone weakening or increased overgrowth, your healthcare provider may want to watch it over time. Careful follow-up with a healthcare provider to monitor bone growth may be advised.
