Clinical Classification Guidelines
Medical Intelligence & Overview
Fibrous dysplasia is a bone disorder characterized by the development of fibrous tissue within the bone, which leads to weakened and deformed bones. The specific form, monostotic fibrous dysplasia, affects a single bone. When this condition involves the lower leg, it can cause noticeable changes in the affected bone's shape and strength, potentially leading to pain or fracture. This condition is often discovered incidentally during imaging tests for other issues but may also present with symptoms that prompt further investigation.
