Polyostotic fibrous dysplasia—more than one bone is involved. It can affect more than one bone within the same limb or multiple bones throughout the body. This form of the condition is usually more severe. For this reason, it is typically discovered earlier in life.
What is Monostotic fibrous dysplasia?
Monostotic fibrous dysplasia is a form of fibrous dysplasia where only one bone is involved. It comprises a majority of the cases of fibrous dysplasia (approximately 70–80%).
What does fibrodysplasia mean?
Fibrous dysplasia is an uncommon bone disorder in which scar-like (fibrous) tissue develops in place of normal bone. This irregular tissue can weaken the affected bone and cause it to deform or fracture.
What are types of fibrous dysplasia?
The main types of fibrous dysplasia include:
- monostotic fibrous dysplasia – only one bone is affected.
- polyostotic fibrous dysplasia – two or more bones are affected.
- McCune-Albright syndrome – fibrous dysplasia can be associated with hormone disturbances and skin pigment changes.
What is a Chondroblastoma?
A chondroblastoma is a rare type of noncancerous bone tumor that begins in cartilage. This is the specialized, gristly connective tissue from which most bones develop. It plays an important role in the growth process. There are many different types of cartilage in the body.
What is shepherd crook deformity?

What is an Adamantinoma?

How do you get FOP?
FOP is caused by a mutation in the ACVR1 gene. This gene is involved in growth and development of bones. The mutation allows them to grow unchecked. The gene can be inherited from one parent, but in most cases of FOP, it’s a new mutation in a person with no family history of the disease.
Is fibrous dysplasia a disability?
Fibrous dysplasia is a condition where primitive bone cells proliferate inside the bone, weakening its structure and causing pain and disability.
Is Osteoblastoma malignant?
Although osteoblastoma is considered a benign tumor, there have been very rare cases in which an osteoblastoma has transformed into a malignant (cancerous) tumor.
Is chondroblastoma painful?
Pain is the most common symptom of a chondroblastoma. Because the tumors are typically found near joints, it is joint pain that will often prompt a visit to the doctor.
What is the difference between monostotic and polyostotic?
is that monostotic is (medicine) pertaining to a single bone while polyostotic is (medicine) pertaining to multiple bones.
What is Monostotic fibrous dysplasia (osteitis fibrosa)?
Monostotic fibrous dysplasia (or monostotic osteitis fibrosa) is a form of fibrous dysplasia where only one bone is involved. It comprises a majority of the cases of fibrous dysplasia. A rare bone disorder characterized by benign bone growths which can cause very painful swellings and bone deformities and makes bone prone to fractures.
