What is osteochondroma femur?

Is exostosis same as osteochondroma?

Exostosis, also called osteoma, is a benign growth of new bone on top of existing bone. It can occur in many parts of the body. When the exostosis is covered with cartilage, it’s called an osteochondroma.

What is an osteochondroma tumor?

Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. 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.

Is osteochondroma a bone spur?

An exostosis, also called a bony spur or osteoma, occurs when a bony growth extend beyond a bone’s usual smooth surface. Exostosis can cause chronic pain or irritation, depending on its size and location. Sometimes, cartilage will grow over an area of exostosis, which is called osteochondroma.

How big is an osteochondroma in the femur?

What kind of bone tumor is an osteochondroma?

Osteochondromas or cartilaginous exostoses are benign bone tumors comprised of a bony prominence with a cartilaginous cap (Geirnaerdt, 1993). Osteochondromas can occur as isolated lesions or less commonly patients have multiple lesions.

Where are solitary osteochondromas found in the body?

As a child grows, a solitary osteochondroma may develop if bone grows out from the growth plate instead of in line with it. Solitary osteochondromas are commonly found at the end of long bones where they meet to form joints, such as the knee, hip, and shoulder. This bone outgrowth may have a stalk or stem that sticks out from the normal bone.

Where does the osteochondroma of the knee originate?

They most commonly arise from the appendicular skeleton, especially around the knee 3: An osteochondroma can be either sessile or pedunculated and is seen in the metaphyseal region typically projecting away from the epiphysis. There is often associated broadening of the metaphysis from which it arises.
