Fibrous dysplasia of the bone

Fibrous dysplasia (FD) of the bone is a peculiar condition that affects either all bones or a single bone in the body. Most cases are diagnosed in adolescence and young adulthood and remain unchanged throughout life. The initial manifestations of fibrous dysplasia are most commonly found in persons aged 3-15 years.

In the past, many conditions that could not be satisfactorily explained have been included under this disease. The bone in this condition is fibrous or plastic in quality and is defective in form as well.
