Prevalence of pain at skeletal sites involved with fibrous dysplasia in adults and children. Sites at which patients reported pain was recorded. 99Tc-MDP bone scans were reviewed to confirm the presence of FD at the reported site of pain. Only those sites at which there was a concordance of pain and FD involvement were recorded. Adults had significantly more pain than children in general (p<0.05), and at both the lower extremity and the spine (p<0.05 for both).
