Kim, Byung Jik; Kim, Yong Uck; Yoo, Moon Jib

Abstract

Fibrous dysplasis is a condition characterized by the metastatic replacement of the medullary component of predominantly long bone with fibrous tissues. This change is responsible for the characteristic features, including bony abnormalities, pathologic fractures and pain. The monostotic form of the fibrous dysplasia occurs more freguent than the polyostotic form. The monostotic fibrous dysplasia does not exhibit the laboratory abnormality, extra-skeletal manifestation or the endocrinopathies associated writh polyostotic disease. Monostotic fibrous dysplasia occurs most frequently in the metaphysis of long bones and the ribs. Only the seven previous cases of vertebral involvement (three cervical, one thoracic, three lumbar spine) in monostotic fibrous dysplsia have been reported. Authors experienced a case of monosotic fibrous dysplasia of the seventh cervical vertebrate, so we report a case with the review of the seven previous reported cases of the monosotic fibrous dysplasia of the spine.
