Hereditary Multiple Exostosis Treatment

Hereditary multiple exostosis is a genetic condition that can be passed down to a child from one parent or occur on its own due to a genetic mutation. It affects bone growth and development, causing bony growths known as exostoses to form in the body. The formation of exostoses stops once a child finishes growing. Any exostoses that are causing a child pain or discomfort should be surgically removed.
