Fibrous dysplasia (FD) is a sporadic benign skeletal disorder that can affect one bone (monostotic form) or multiple bones (polyostotic bone). Around 6–20% of monostotic FD occurs in the ribs. The objective of this study was to report our experience in the management of the monostotic FD of the ribs. Between January 2004 and December 2009, seven cases of FD of the rib (six men and one woman, mean age 30.4 years, range 17–40 years) were operated on. The patients were evaluated with plain radiographs and computer tomography (CT). All our patients were symptomatic; two patients presented chest pain and swelling and other patients presented only chest pain. One rib was involved in all our patients (monostotic form): the site was fifth rib (four cases), sixth rib (two cases) or second rib (one case). Radiologically, plain films and CT showed an expansible lesion with a ground-glass centre and thinning of the cortex. Rib resection was performed in all patients; there were no postoperative complications and no recurrence in all cases at mean 43 month follow-up. In symptomatic monostotic FD of ribs, the involved segment of bone may be excised to rule out malignancy and for painful lesions.
