Fibrous dysplasia of bone
Fibrous dysplasia of bone (pronunciation: fy-bro-us dis-play-zee-uh of bohn) is a bone disorder where normal bone is replaced with fibrous bone tissue. This condition can lead to abnormal growth or swelling of the bone, and it may affect one bone (monostotic) or multiple bones (polyostotic).
Etymology
The term "fibrous dysplasia" is derived from the Greek words "fibra" (meaning fiber), "dys" (meaning bad or difficult), and "plasia" (meaning formation). Thus, it refers to the abnormal formation or development of fibrous tissue.
Symptoms
Fibrous dysplasia of bone can cause a variety of symptoms, including bone pain, bone deformities, and fractures. The severity of these symptoms can vary widely, depending on which bones are affected and the extent of the disease.
Causes
Fibrous dysplasia of bone is caused by a mutation in the GNAS gene. This mutation is not inherited, but occurs randomly in some cells during a person's lifetime.
Diagnosis
Diagnosis of fibrous dysplasia of bone typically involves a combination of physical examination, medical history, imaging tests such as X-ray or CT scan, and sometimes a bone biopsy.
Treatment
Treatment for fibrous dysplasia of bone is usually aimed at managing symptoms and preventing complications. This may include pain management, physical therapy, and in some cases, surgery to correct bone deformities or fractures.
