Does Osteogenesis Imperfecta in children with fracture is treatable by physical therapy?

Osteogenesis Imperfecta (OI), commonly known as brittle bone disease, is a genetic disorder characterized by fragile bones that are prone to fractures. This condition poses significant challenges, especially in children, as their growing bodies require effective management to ensure optimal development.

Physical therapy emerges as a cornerstone in the comprehensive care and recovery process for children with OI, offering tailored interventions to enhance strength, mobility, and overall quality of life.

What is osteogenesis imperfecta (brittle bone disease)?

 Osteogenesis imperfecta:

Brittle bone disease, also known as osteogenesis imperfecta (OI), is a genetic disorder that affects the bones, making them fragile and prone to fractures. It’s present at birth and can range from mild to severe in its effects.

Types:

Children with osteogenesis imperfecta have a higher risk of fractures than children without the condition. There are eight types of OI, which vary in severity. Here are the four most common types of osteogenesis imperfecta in children with fractures:

1. Type I: This is the mildest and most common type of OI, affecting about 50% of all children with OI. Children with type I OI may have a few fractures throughout their childhood, but they usually don’t have any bone deformities. The first fracture often happens when the child starts walking. Fractures usually happen less often after puberty.
2. Type III: This is a severe type of OI. Babies with type III OI may have broken bones at birth, and they may have bone deformities as they grow older. They may also have short stature, loose joints, and brittle teeth.
3. Type IV: This type of OI can range from mild to severe. Children with type IV OI may have their first fracture before puberty. They may also have mild to moderate bone deformities.
4. Type V: This type of OI is similar to type IV OI, but children with type V OI may also have enlarged, thickened areas of bone (calluses) at the sites of fractures.

Causes:

Osteogenesis imperfecta (OI) is a genetic disorder that affects the connective tissues throughout the body, primarily causing bones to be brittle and prone to fracture.  The main cause of OI is a gene mutation that affects the production of type I collagen, the major structural protein in bones.

There are two main types of inheritance for OI:

1. Autosomal dominant: This is the most common type of inheritance for OI, accounting for about 80-90% of cases. In autosomal dominant inheritance, a person only needs one copy of the mutated gene to have OI. This gene can be inherited from either parent, or it can be a new mutation that occurs in the egg or sperm cell.
2. Autosomal recessive: This type of inheritance is less common, accounting for about 10-20% of cases. In autosomal recessive inheritance, a person needs two copies of the mutated gene to have OI. These genes are usually inherited from both parents, who are carriers of the mutation but do not have OI themselves.

There are also rare cases of OI that can be caused by mutations in other genes. These cases are often more severe and can have additional features, such as loose joints or heart problems.

Symptoms:

 The main symptom is frequent fractures, even with minimal bumps or knocks. Other symptoms can include:

1. Short stature
2. Joint hypermobility (loose joints)
3. Scoliosis (curvature of the spine)
4. Hearing loss
5. Breathing problems
6. Blue sclerae (blue whites of the eyes)
7. Dentinogenesis imperfect (brittle teeth)

Severity:

Osteogenesis imperfecta can be classified into several types based on its severity and genetic cause. These types range from mild cases with few fractures to severe cases with multiple fractures, bone deformities, and other complications.

What kind of role does physical therapy play in recovering from fractures in children with osteogenesis imperfecta?

 Role of physical therapy

Here’s how physical therapy plays a crucial role in recovery for children with Osteogenesis imperfecta:

1. Safely Regaining Strength and Motion: Immobilization is often necessary following a fracture, but it can lead to muscle weakness and stiffness. Physical therapists design personalized exercise programs that address these concerns without stressing healing bones. This might include gentle range-of-motion exercises, weight-bearing activities adapted to tolerate weaker bone density, and aquatic therapy, which offers buoyancy and pain relief.
2. Preventing Future Fractures: Building strong muscles around the bones creates a protective support system, reducing the risk of future fractures. Therapists use techniques like strengthening exercises, balance training, and coordination drills to improve movement patterns and minimize the impact of everyday activities on skeletal health.
3. Pain Management: Chronic pain can be a significant issue for children with OI. Physical therapists can offer manual therapy techniques, massage, and heat therapy to ease pain and discomfort, making the recovery process more tolerable and allowing children to participate in activities more freely.
4. Emotional and Psychological Support: A diagnosis of OI can be frightening for both children and families. Physical therapists play a crucial role in providing emotional support and guidance. They help children understand their condition, address fears and anxieties, and set realistic goals for recovery. This empowers children to take control of their health and fosters a positive outlook on life with OI.
5. Collaboration and Advocacy: Physical therapists work closely with other healthcare professionals like doctors, nurses, and occupational therapists to ensure a coordinated approach to recovery. They also advocate for children with OI, educating and collaborating with schools, caregivers, and communities to create safe, supportive environments that promote optimal physical and emotional well-being.

Beneficial Exercises for osteogenesis imperfecta

Gentle range-of-motion exercises

These exercises help to move the joints around the fracture and prevent stiffness. They can be done passively, by a parent or therapist moving the child’s limb, or actively, by the child moving their limb on their own.

Here are some examples of gentle ROM exercises for children with osteogenesis imperfecta:

Neck:

1. Side bends: Gently tilt your head towards one shoulder, hold for a few seconds, and then repeat on the other side.
2. Forward and backward bends: Slowly nod your head down towards your chest and then back up.

Shoulder:

1. Arm circles: Make small circles with your arms, forward and backward.
2. Shoulder shrugs: Slowly raise your shoulders towards your ears, hold for a few seconds, and then relax.

Elbow:

1. Bent arm circles: With your elbow bent at a 90-degree angle, make small circles with your forearm.
2. Elbow flexion and extension: Slowly bend and straighten your elbow.

Wrist:

1. Wrist circles: Make small circles with your wrists, forward and backward.
2. Wrist flexion and extension: Slowly bend your wrist down towards your palm and then back up.

With proper guidance and care, ROM exercises can help children with osteogenesis imperfecta (OI) heal from fractures and maintain their joint health.

Strengthening exercises:

Children with osteogenesis imperfecta can benefit from strengthening exercises to help improve muscle strength and function, and reduce the risk of future fractures. However, it’s important to note that any exercise program for a child with  osteogenesis imperfecta should be supervised by a physical therapist or other qualified healthcare professional. They can develop a safe and appropriate program based on the child’s individual needs and limitations.

Examples:

Here are some general examples of strengthening exercises that may be appropriate for children with osteogenesis imperfecta following a fracture:

Isometric exercises:

Isometric exercises can be a safe and effective way to maintain muscle strength and bone health in children with osteogenesis imperfecta (OI) who have sustained a fracture. These exercises involve contracting the muscles without any movement at the joints. This can help to improve bone density and reduce the risk of future fractures.

Here are some examples of isometric exercises that may be appropriate for children with OI:

1. Squeezing a ball: This can be done with a small, soft ball. The child can squeeze the ball as hard as they can for a few seconds, and then relax.
2. Pushing against a wall: The child can stand facing a wall and push their hands against the wall for a few seconds. They can then relax and repeat.
3. Tensing the tummy muscles: The child can lie on their back and tighten their tummy muscles for a few seconds. They can then relax and repeat.

Additional Tips:

Here are some additional tips for performing isometric exercises safely:

1. Start with low-intensity exercises and gradually increase the intensity as tolerated.
2. Do not hold your breath while performing the exercises.
3. Breathe normally and relax your shoulders throughout the exercises.

FAQ’s 

How are fractures treated in osteogenesis imperfecta?

There is no one-size-fits-all treatment for fractures in osteogenesis imperfecta (OI), as the approach will depend on the severity of the fracture and the individual’s overall health. However, some general principles apply:

1. Casting and splinting: This is a common way to immobilize and support fractured bones in people with OI. However, healthcare providers will try to minimize casting time as much as possible to prevent bone weakening.
2. Bracing: Braces can help protect bones from future fractures and provide support for healing fractures.
3. Medication: Bisphosphonate medications are the mainstay of drug treatment for OI. They help to increase bone mineral density and reduce the risk of fractures.
4. Surgery: In some cases, surgery may be necessary to correct bone deformities or to implant rods to stabilize fractured bones. This is especially common for long bone fractures in the legs.

Additional Tips:

Here are some additional things to keep in mind about fracture treatment in OI:

1. Early intervention is important. The sooner a fracture is treated, the better the chance of a full recovery.
2. Physical therapy is often an important part of treatment. Physical therapy can help to improve strength, flexibility, and balance, which can help to prevent future fractures.
3. Pain management is important. People with OI may experience more pain than usual after a fracture. Healthcare providers will work to control pain so that people with OI can participate in therapy and other activities.

Can you walk with osteogenesis imperfecta?

Whether someone with osteogenesis imperfecta (OI) can walk depends on the severity of their condition.  OI is a genetic disorder that causes bones to be fragile and break easily. There are four main types of OI, with type I being the mildest and type IV being the most severe.

People with mild OI may have few fractures and may be able to walk without any problems.  However, people with more severe OI may fracture bones frequently, even with minimal trauma.  This can make it difficult or impossible for them to walk.  In some cases, people with OI may need to use a wheelchair or other mobility aids.

What is the diet for osteogenesis imperfecta?

There isn’t a specific diet cure for osteogenesis imperfecta (OI) since it’s a genetic disorder. However, a balanced diet that promotes bone health is recommended. This means focusing on foods rich in:

1. Calcium: Dairy products like milk, cheese, and yogurt are rich sources of calcium. For those who are lactose intolerant or vegan, calcium-fortified alternatives like plant-based milk, tofu, and leafy green vegetables can be good substitutes.
2. Vitamin D: Vitamin D helps your body absorb calcium. It can be found in fatty fish like salmon and tuna, as well as egg yolks and fortified foods like milk and cereals. Sunlight exposure can also help your body produce vitamin D.
3. Vitamin C:Vitamin C is important for collagen production, which is a major component of bones. Fruits and vegetables like citrus fruits, strawberries, bell peppers, and broccoli are all loaded with vitamin C.

Additional Tips:

Here are some additional tips for a bone-healthy diet for OI:

1. Maintain a healthy weight: Being overweight can put extra stress on bones, so it’s important to maintain a healthy weight through a balanced diet and regular exercise.
2. Limit processed foods: Processed foods are often high in unhealthy fats, sodium, and added sugar, which can contribute to weight gain and other health problems.
3. Stay hydrated: Drinking plenty of fluids throughout the day is important for overall health, including bone health.

It’s important to consult with a doctor or registered dietitian for personalized advice on creating a diet plan that meets your specific needs and preferences. They can also help you determine if calcium and/or vitamin D supplements are necessary.
