Note: this is the same as Osteomyelitis
Osteomyelitis is an infection of the bone. Early diagnosis and treatment is important to prevent serious complications. From mild to severe cases of osteomyelitis, our pediatric orthopedic specialty team is experienced in the diagnosis and treatment bone infections. Our goal to help the bone to heal properly and your child recover as quickly as possible.
Osteogenesis imperfecta, or brittle bone disease, is a genetic disorder that prevents the body from building strong bones. People with osteogenesis imperfecta might have bones that break easily, which is why the condition is commonly called brittle bone disease.
Brittle bone disease happens because of a defect in the gene that makes the protein collagen. Collagen is an important building block of bones.
People who have brittle bone disease are born with it. They either don't have enough collagen in their bones or have collagen that doesn't work as it should. This makes their bones weaker and more brittle than normal bones. It can also lead to bone deformities. (Deformed bones do not have normal shapes.)
The defect in the gene can be inherited from a parent. Kids with this disease often have a parent who has the condition. Sometimes, the defect in the gene happens spontaneously at the time of conception.
Doctors classify the different types of brittle bone disease based on how severe the condition is. To date, 15 types have been identified.
Most people have symptoms that fall into one of these four classifications:
Type I osteogenesis imperfecta - people with type I OI have less collagen than normal. This makes their bones fragile, but they don't have bone deformities. The first break usually happens when a child starts walking. Fractures typically decrease after puberty.
Type II osteogenesis imperfecta - babies with type II OI usually are born with many fractures, are very small, and have severe breathing problems. As a result, most will not survive.
Type III osteogenesis imperfecta - people with type III OI usually will be shorter than their peers, and may have severe bone deformities, breathing problems (which can be life-threatening), brittle teeth, a curved spine, ribcage deformities, and other problems.
Type IV osteogenesis imperfecta - people with type IV OI can have mild to serious bone deformities, short stature, frequent fractures (which may lessen after puberty), and a curved spine.
The severity of osteogenesis imperfecta can vary. Some people won't know they have it until they fall and break a bone. For them, the only symptom might be an occasional broken bone. Other people can have many bone breaks without any obvious cause. Signs include:
Your doctor will ask about your family history of brittle bone disease. In addition the doctor ask about frequent or unexplained bone fractures and look for dental problems, blue sclera (the white part of the eye), short stature, and other symptoms as signs that your child has the condition. They might also order tests like:
In severe cases, prenatal testing (such as an ultrasound) can detect fractures and bone deformities before a baby is born.
There's no cure for osteogenesis imperfecta. Treatment is based on a child's specific symptoms, and can include physical therapy and mobility aides, occupational therapy, medicine, and surgery. The goal is to prevent fractures, treat them properly when they do happen, preserve mobility and independence, and strengthen bones and muscles.
The treatment team might include a primary care doctor, an orthopedist, rehabilitation specialists, an endocrinologist, a geneticist, a neurologist, and a pulmonologist.
Preventing bone fractures is key for people with OI. They can lower their risk of broken bones by:
When bones do break, it's important to treat them right away with casts, splints, and braces. Orthopedists (doctors who specialize in treating bone problems) might recommend using lightweight versions of these devices that allow some movement during healing.
Physical therapy (PT) can be helpful for many kids with OI. It can build muscle strength, which helps maintain function, promote aerobic fitness, and improve breathing. Kids who need them can learn how to use mobility aides and assistive devices. In younger kids, PT can help with motor skill development.
Doctors might prescribe bone-strengthening medicines to increase bone density and further reduce the chances of fractures. Some people will need treatment to maintain bone strength for the rest of their lives.
Sometimes, surgery is needed to repair a broken bone or fix a deformity. Surgeons also might place metal rods into long bones (like the femur, tibia, and humerus) to prevent breaks. Surgery also can correct dental problems from brittle teeth, and help with hearing problems.
Bone breaks due to brittle bone disease usually lessen in early adulthood, although they can start happening again later in life.
Taking steps to prevent fractures — along with early, ongoing medical care - will help most people lead healthy, productive lives.
