Fibrous dysplasia happens when healthy bone is replaced with other types of tissue. Bones may become weak, oddly shaped, or even break. You may also feel pain.
The disease can affect any bone in the body. The most common bones affected are in the skull and face, leg bones, upper arm, pelvis, and ribs. Affected bones are often found on one side of the body, although the disease does not spread from one bone to another.
