Living with osteogenesis imperfecta living

Overview

Osteogenesis imperfecta, often called brittle bone disease, is a genetic condition that makes bones fragile and more likely to break. The word 'imperfecta' means 'incomplete' – in this condition, the body does not make enough collagen (the protein that gives bones their strength), so bones are weaker than they should be. While there is no cure, many people with osteogenesis imperfecta live full, active lives with proper care and support.

Osteogenesis imperfecta is rare. It affects about 1 in 10,000 to 20,000 people worldwide.

It affects both males and females equally and occurs in all ethnic groups. It is present at birth, but the severity can range from mild to severe. Some people inherit it from a parent, while others are the first in their family to have it.

Symptoms

Common symptoms

• Bones that break easily, especially with little or no trauma
• Bone pain and frequent fractures
• Short stature (being shorter than average)
• Loose joints and low muscle tone
• Blue or grey tint to the whites of the eyes
• Hearing loss that may begin in early adulthood
• Curved bones, such as bowing of the arms or legs
• Triangular face or unusually shaped skull

Symptoms in children

• Fractures during or shortly after birth
• Frequent bruising or broken bones in infancy and toddler years
• Delays in sitting, crawling, or walking because of weak bones and muscles
• Small size for age
• Enamel defects and dental problems – teeth may be brittle or discoloured

Symptoms in older adults

• Fractures that happen more easily with age
• Hearing loss due to changes in the bones of the middle ear
• Curvature of the spine (scoliosis)
• Breathing problems if the rib cage is affected
• Chronic bone or joint pain

Causes

Main causes

• A genetic change (mutation) in the genes that control the production of type 1 collagen, the main protein in bone.
• Having a family history of osteogenesis imperfecta, although many cases occur randomly as new genetic changes.

Risk factors

• Having a parent or sibling with osteogenesis imperfecta.
• Inheriting the condition from one affected parent (autosomal dominant pattern) – this is the most common pattern.
• In rarer forms, inheriting it from both parents (autosomal recessive pattern) – this usually leads to more severe disease.

When to see a doctor

See a doctor urgently if:

• If you or your child has a suspected fracture – do not wait for a routine appointment.
• If there is severe pain, swelling, or difficulty moving a limb after a fall.
• If there is any sign of a head injury or breathing trouble.

Book a routine appointment if:

• If you notice your child is breaking bones more easily than seems normal.
• If there is early hearing loss, especially if you also have a history of fragile bones.
• If you have joint pain, spinal curvature, or mobility problems that are beginning to affect daily life.
• If you are planning a family and have a personal or family history of osteogenesis imperfecta.

Diagnosis

A doctor diagnoses osteogenesis imperfecta by carrying out a physical examination, asking about family and medical history, and checking for typical signs such as frequent fractures, blue sclera, or hearing loss. Imaging tests and genetic tests can help confirm the diagnosis and identify the type.

Tests that may be done

• X-rays to look at the shape and structure of bones and to spot old fractures that were not previously noticed.
• Bone density scan (DXA) to measure how strong the bones are.
• Genetic test – a blood or saliva sample that looks for changes in collagen genes.
• Sometimes a skin biopsy (removing a tiny piece of skin) to measure collagen quality, though this is less common today.

What to expect at your appointment

Your doctor will explain what type of osteogenesis imperfecta you or your child likely has and how severe it may be. There is no single severity score – the condition affects everyone differently. The doctor will then build a care team that may include an orthopaedic surgeon, physiotherapist, occupational therapist, hearing specialist, and dentist, depending on your needs.

Treatment

Treatment aims to reduce the risk of fractures, manage pain, and improve mobility and independence. A team approach is best, and care plans are individualised. There is no cure, but with the right treatment, most people can do many of the things they want to do.

Self-care at home

• Learn safe ways to move and handle the body, especially when lifting or holding a child.
• Use adaptive equipment, such as cushioned car seats, padded splints, or long handled tools, to reduce strain on bones.
• Keep the home environment free of trip hazards – for example, remove loose rugs and keep walking paths clear.
• Maintain a healthy weight, as extra weight puts additional stress on bones.
• Avoid contact sports or high-risk activities, but do not become inactive – gentle activity helps maintain muscle and bone strength.
• Wear supportive footwear to reduce the risk of trips, slips, and falls.

Medical treatments

Some people may be prescribed medicines that help slow bone loss and improve bone strength. These medicines belong to a class called bisphosphonates, but other types may also be used. Your healthcare team will discuss whether such treatment is appropriate, what benefits they expect, and what side effects to watch for. Do not start any bone-related medication without a proper medical assessment.

When is surgery considered?

Surgery is sometimes needed to straighten curved bones or to insert metal rods into long bones. These rods help support weakened bones and can reduce the number of fractures. Surgery is not right for everyone, but it can greatly improve mobility and quality of life for those who need it.

Living with this condition

Living with brittle bone disease means planning carefully but not giving up on life. You or your child may need to adapt how you do everyday tasks, but with good support, most people can go to school, work, and enjoy hobbies. The key is to know your limits while also challenging yourself safely.

Lifestyle tips

• Choose low-impact activities such as swimming or gentle cycling, which are easier on the bones.
• Consider physical therapy to improve muscle strength and balance, which can help prevent falls.
• Protect the spine – ask your therapist for safe ways to bend, lift, and carry.
• Make every room in the home safer – install grab bars, handrails, and non-slip mats.
• Stay socially connected and let family, friends, and employers know how they can support you.

Diet and exercise

Eat a balanced diet rich in calcium and vitamin D, which are important for all bones, but remember that diet alone cannot correct the genetic weakness of osteogenesis imperfecta. A doctor or dietitian can advise on supplements if needed. Exercise is beneficial, but it must be carefully chosen – a physiotherapist can help design a safe programme that strengthens muscles without putting high stress on bones.

Mental health and emotional wellbeing

Living with a chronic bone condition can sometimes feel exhausting and isolating. People may worry about future fractures or about being a burden. These feelings are normal, and it is important to talk about them. Mental and emotional support is just as important as physical care.

Prevention

Osteogenesis imperfecta itself cannot be prevented because it is a genetic condition. However, the risk of fractures can be reduced with good bone care, safe movement, and avoiding activities that are more likely to cause injury. If you have a family history and are planning a family, a genetic counsellor can help you understand the chances of passing the condition to your children.

Vaccines

It is a good idea to stay up to date with routine vaccines, including the flu and COVID-19 vaccines, as respiratory infections can be harder to recover from if you have chest or spine involvement. Always talk to your doctor about which vaccines are right for you.

Screening programmes

People with a family history may consider genetic testing before having children to understand their options. Children born into a family with osteogenesis imperfecta may be checked early with imaging and physical examination. Routine screening for hearing loss and dental issues is also important for people already living with the condition.

Complications

If left untreated

• More frequent and more painful fractures
• Progressive bone deformities, such as bent bones or curvature of the spine
• Chronic pain and mobility loss
• Hearing impairment that can affect communication and quality of life
• Breathing problems if the chest wall is severely affected

Long-term outlook

Most people with osteogenesis imperfecta live a normal or near-normal lifespan. With good medical care, physiotherapy, and a strong support network, many people have successful careers, raise families, and enjoy active hobbies. There will be challenges, but there is real hope and help available at every stage of life.
