Abstract

Fibrous dysplasia represents a disturbance of normal bone development specifically a defect in osteoblastic differentiation and maturation that originates in the mesenchymal precursor of the bone. In fibrous dysplasia, the lesion expands, which leads to a distortion and weakening of bone. Although the lesion is not encapsulated, it tends to remain enclosed within a shell of cortical bone. This shell can be thinned as a result of the pressure exerted on it. As it slowly progresses, fibrous dysplasia can cause skeletal destruction and deformity.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
