Fibrodysplasia Ossificans Progressiva Overview

Another name for Fibrodysplasia Ossificans Progressiva is Myositis Ossificans.

What is myositis ossificans?
A person with myositis ossificans has abnormal bone that forms within the muscle tissue. There are two main types of myositis ossificans: myositis ossificans circumscripta and myositis ossificans progressiva. Myositis ossificans circumscripta is caused by a muscle injury. Myositis ossificans progressiva is an inherited condition that causes bone to form in many tissues outside of the skeleton.

What are the symptoms of myositis ossificans?
Symptoms depend on the type of myositis ossificans. Symptoms of myositis ossificans circumscripta include pain, swelling, and a lump within the muscle tissue. Symptoms of myositis ossificans progressiva include deformed fingers and toes, painful lumps around the joints, an abnormally curved spine, and decreased range of motion in the hips and shoulders.

How does the doctor treat myositis ossificans?
Treatment of myositis ossificans may include corticosteroids, nonsteroidal anti-inflammatory medications, narcotic pain medications, and surgery.
