Osteogenesis Imperfecta

Osteogenesis imperfecta (OI) is a category of bone-related hereditary diseases. Osteogenesis imperfecta means faulty bone production. Bones shatter quickly in people with this disorder. Frequently due to minor trauma or no obvious cause. It is not uncommon for many fractures to develop even before birth. Milder cases may only cause a few fractures in a lifetime.

The signs and symptoms of several categories overlap. Rarer variants of osteogenesis imperfecta are increasingly defined genetically. Type I (typical non-deforming osteogenesis imperfecta with blue sclerae) is the mildest variant. On the other hand, Type II is the most severe (perinatally fatal osteogenesis imperfecta). Types III (progressively deforming osteogenesis imperfecta) and IV (common variable osteogenesis imperfecta with normal sclerae) have indications and symptoms in between.

What causes Osteogenesis Imperfecta?

Osteogenesis imperfecta (os-tee-oh-JEN-uh-sis im-pur-FEK-tuh) occurs due to a gene deficiency that produces collagen. Collagen is a major component of bones.

Also, Osteogenesis Imperfecta is a genetic condition. They either don’t have enough collagen or it’s not working properly. This weakens and brittles their bones. This can cause bone abnormalities. Normal bones are not deformed.

A parent can pass on a gene flaw. Kids with OI frequently have a sick parent. A gene deficiency can occur spontaneously during conception.


Breaking bones is the most common sign of brittle bone disease. They are prone to breaking. Someone suffering from the illness may experience only a few fractured bones in their lifetime. Or they may experience hundreds of them. In other instances, symptoms do not manifest themselves until the adolescent years or later. General symptoms of brittle bone disease can range from minor to severe. depending on the severity of the condition. They are as follows:

Bone fractures (fractures).

Bruising and bleeding are common (frequent nosebleeds or heavy bleeding after an injury).

The whites of the eyes have a blue tint to them.

Legs are bowed inward.

Breathing difficulties.

Teeth that are brittle and discolored.

Scoliosis is a term used to describe a curved spine.

I’m feeling quite exhausted.

Skin that is prone to injury.

Hearing loss begins in adolescence or early adulthood.

I can’t take being in hot weather.

Joints that are a little loose.

a person of average height.

Muscles and tissues that are in poor condition.

Brittle bone disease is classified into kinds by doctors. Depending on the symptoms and the number of fractures that have occurred.

Dominant OI

There is one dominant type in the vast majority of patients with OI. In other words, they receive one normal copy of the gene and one copy of the gene responsible for OI. The faulty copy of the gene is more powerful than the normal copy of the gene. And it is referred to as being “dominant.” A person develops OI as a result of this. Each of a person’s offspring who inherits a dominant mutation has a 50% probability (1 in 2) of inheriting the condition from their mother.

The dominant type of OI is inherited by some people. While others are born with it despite the fact that they have no family history of it. And the mutation arises in their genome for the first time in their family.

Recessive OI

The disease has a recessive form in certain people who suffer from OI. The condition is inherited from both parents. Who do not have OI but who both have a defective gene that produces the disease in their offspring (recessive OI). Additionally, when both parents inherit the recessive gene for OI, there is a 25 percent risk (1 out of 4) of having a kid. Who has the disease during each pregnancy. Moreover, families with recessive OI who have unaffected or asymptomatic siblings are twice as likely. As those who have symptomatic siblings have an aberrant gene that causes OI. Making them carriers of the disease (2 out of 3 chances). As a result, due to a recessive mutation, if one parent has OI. All of their offspring will possess an aberrant gene that causes OI. However, they will not necessarily develop OI.

The following are the most prevalent kinds of brittle bone disease:


only a few indicators of the illness.

There is little or no bone deformation.

The number of shattered bones ranged from a few to several hundred.

Height is not frequently a consideration.

Premature hearing loss is a possibility.

After puberty, the number of broken bones decreases.

Osteogenesis Imperfecta (OI) Treatment

Osteogenesis imperfecta has no treatment. Depending on the child’s symptoms. Treatment may involve physical therapy, occupational therapy, medicine, or surgery. Furthermore, bone and muscular strength are important in preventing fractures. Also in treating them correctly when they occur.

Also, your doctor, an orthopedist, rehabilitative expert, an endocrinologist, a geneticist, and a pulmonologist may be on your treatment team.

Keeping Bones Strong

OI patients must avoid bone fractures. They can avoid shattered bones by taking low-impact exercises (like swimming). To enhance muscular strength and mobility. And strengthen bone strength avoiding activities that put them at risk for falls or collisions

Handling Fractures

If a bone breaks, it must be treated immediately using casts, splints, and braces. Furthermore, Obstetricians and Gynecologists may prescribe utilizing lightweight versions of these devices. Where these allow movement during recuperation.


Many children with OI benefit from PT. It can increase muscle strength, aerobic fitness, and breathing. Aides and mobility aids can be taught to children who need them. Consequently, PT can assist young children to develop motor skills.

Additionally, Medication Doctors may administer bone-strengthening medications to boost bone density and reduce fracture risk. Some patients will need lifelong treatment to keep their bones strong.


A damaged bone or deformity may require surgery. Long bones (such the femur, tibia, and humerus) may also be strengthened with metal rods. Surgery can also help with oral issues like brittle teeth and hearing issues.

Living with Osteogenesis Imperfecta

Living with Osteogenesis Imperfecta is a difficult experience for many people.
Individuals suffering from OI may benefit from certain activities. That may help them stay healthy and avoid fractured bones.

Take care to eat a well-balanced diet.
Make every effort to stay active. Strengthening muscles and bones with regular physical activity might be beneficial. When it comes to people with OI. Swimming and water treatment are popular options. This is because exercising in the water has a low risk of suffering broken bones. In order to choose the most appropriate and safe form of exercise, consult with your doctor or physical therapist.

Furthermore, maintain a normal weight. In addition, extra weight puts stress on the bones, which is particularly harmful to persons who have osteoporosis.
Finally, to keep your bones strong, avoid using tobacco and secondhand smoke. Smoking can also cause bone deterioration.
