Exostosis
Exostosis
Exostosis (pronounced: ex-oh-stow-sis) is a medical condition characterized by the formation of new bone on the surface of a bone. Exostoses can cause chronic pain and discomfort, depending on the size and location of the growth.
Etymology
The term "exostosis" is derived from the Greek words "exo", meaning outside, and "osteon", meaning bone. Thus, it literally translates to "bone growing outward".
Definition
Exostosis is a benign growth that protrudes from the surface of a bone. It is often caused by trauma or repetitive activity that damages the bone. The body responds by creating new bone tissue, but instead of integrating it into the existing bone, it forms a separate growth.
Symptoms
Symptoms of exostosis can vary greatly depending on the location and size of the growth. Some common symptoms include:
- Pain and discomfort
- Limited range of motion
- Swelling or lump in the affected area
- Numbness or tingling if the growth is pressing on a nerve
Diagnosis
Diagnosis of exostosis typically involves a physical examination and imaging tests such as X-rays, CT scans, or MRI scans. These tests can help determine the size and location of the growth.
Treatment
Treatment for exostosis often involves managing symptoms and preventing further growth. This can include pain management, physical therapy, and in some cases, surgical removal of the growth.
