Bone Growth Stimulators: A Guide to Non-Surgical Healing Acceleration

Bone Growth Stimulators: Types, Working, Benefit, Treatment Process | The Lifesciences Magazine

The human body possesses a remarkable ability to heal itself, including mending broken bones. However, certain factors like age, health conditions, or complex fractures can sometimes hinder this natural process. In such cases, medical professionals may recommend the use of a bone growth stimulator.

What is a Bone Growth Stimulator?

A bone growth stimulator, also known as low-energy bone stimulation (LEBS) therapy, is a non-invasive or minimally invasive medical device that aids in accelerating the healing of fractures and promoting bone growth. These devices deliver low-intensity pulsed ultrasound waves or electromagnetic fields to the affected area, stimulating cellular activity and promoting bone formation.

How Do Bone Growth Stimulators Work?

The exact science behind how bone growth stimulators work is still under investigation. However, research suggests they influence bone healing through several mechanisms:

1. Increased Blood Flow

The low-level energy delivered by the device stimulates blood flow to the injured area, delivering essential nutrients and oxygen needed for bone repair.

2. Cellular Activity

The stimulation may enhance the activity of osteoblasts, the cells responsible for bone formation.

3. Bone Mineral Density

Bone growth stimulators may also promote the deposition of minerals, leading to increased bone density at the fracture site.

Types of Bone Growth Stimulators:

There are two main types of bone growth stimulators:

1. External Bone Growth Stimulators

These are the most common type and are non-invasive. They consist of a control unit connected to electrodes or coils placed on the skin over the fracture site. The device transmits low-intensity pulsed ultrasound waves or electromagnetic fields to stimulate the bone.

2. Implantable Bone Growth Stimulators

These are less common and used in specific situations. They involve surgically implanting a small device directly at the fracture site. The device delivers continuous stimulation for a predetermined period.

Who Can Benefit from a Bone Growth Stimulator?

Bone growth stimulators are not a one-size-fits-all solution. While they offer a promising alternative to surgery or prolonged immobilization, they are most effective for specific conditions. Here are some scenarios where a doctor might recommend this therapy:

1. Non-union Fractures

When a fracture fails to heal on its own after several months, a bone growth stimulator may be used to stimulate bone formation and promote healing.

2. Delayed Unions

In some cases, the healing process for a fracture might be slower than expected. A bone growth stimulator can help accelerate healing and prevent non-union from developing.

3. Spinal Fusion Surgery

Bone growth stimulators can be used after spinal fusion surgery to promote bone growth and improve the success rate of the procedure.

4. Osteoporosis

In some cases, bone growth stimulators may be used to increase bone density in individuals with osteoporosis, particularly for specific fractures.

Benefits of Using Bone Growth Stimulators:

There are several advantages associated with using a bone growth stimulator:

1. Non-invasive or Minimally Invasive

Unlike surgery, external bone growth stimulators are non-invasive, avoiding the risks associated with surgical procedures. Implantable devices do involve surgery, but it is typically minimally invasive.

2. Pain Reduction

By accelerating healing, bone growth stimulators can potentially help reduce pain associated with a fracture.

3. Improved Mobility

Faster healing often translates to quicker recovery and improved joint mobility.

4. Reduced Hospital Stay

In some cases, bone growth stimulators can help patients avoid prolonged hospitalization or rehabilitation.

Who Should Not Use a Bone Growth Stimulator?

While generally safe, bone growth stimulators might not be suitable for everyone. Here are some contraindications:

1. Pacemakers or Defibrillators

The electromagnetic fields emitted by some bone growth stimulators can interfere with implanted cardiac devices.

2. Cancer

Bone growth stimulators are not recommended for individuals with active cancer in the affected area.

Bone cancer prognosis provides valuable insights into the likelihood of recovery, recurrence, and overall survival rates for patients. It helps healthcare providers and patients understand the potential challenges and outcomes associated with the disease

3. Pregnancy

There is limited research on the safety of bone growth stimulators during pregnancy.

4. Infection

The presence of infection at the fracture site is a contraindication for using a bone growth stimulator.

What to Expect During Bone Growth Stimulator Treatment?

The prospect of using a bone growth stimulator might raise questions about the treatment process. Here’s a breakdown of what you can expect:

1. Consultation and Assessment

The journey begins with a doctor’s consultation. They will meticulously evaluate your condition, medical history, and X-rays. This helps determine if you’re a suitable candidate for bone growth stimulator therapy.

2. Treatment Plan and Device Selection

If deemed suitable, the doctor will prescribe the specific type of bone growth stimulator based on your needs. This could be an external device with electrodes or coils placed on the skin, or a less common implantable device surgically positioned near the fracture.

3. Treatment Schedule and Device Use

The doctor will establish a treatment schedule, typically involving several hours of daily use for a period of months. They’ll provide detailed instructions on using the device, including proper placement, operation, and maintenance.

4. Living with a Bone Growth Stimulator

Bone growth stimulator therapy integrates seamlessly into your daily routine. The devices are often lightweight and portable, allowing you to wear them while performing most activities. You can continue working, attending appointments, or even exercising (with doctor’s approval) while undergoing treatment.

5. Follow-up Appointments

Regular follow-up appointments with your doctor are crucial. These visits allow them to monitor progress, assess healing through X-rays, and ensure the device is functioning optimally. The doctor might adjust treatment parameters as needed based on your response.

6. Potential Side Effects

Bone growth stimulators are generally well-tolerated, but some mild side effects might occur. These could include temporary skin irritation at the electrode or coil site, or occasional muscle soreness near the treated area. If you experience any discomfort, speak to your doctor.

7. Completion of Treatment

Once the prescribed treatment duration is complete, the doctor will reassess the healing progress. Depending on the results, they might recommend continuing physical therapy or specific exercises to regain full strength and mobility in the affected area.

Remember, successful healing often involves a combination of therapies. Bone growth stimulators work synergistically with your body’s natural healing processes, potentially accelerating recovery and improving outcomes.


While traditional methods like casting and surgery remain important tools for fracture management, bone growth stimulators offer a revolutionary non-surgical or minimally invasive approach. These devices hold immense promise for accelerating healing timelines, reducing pain, and improving mobility outcomes. If you’re facing a delayed or non-union fracture, discussing bone growth stimulator therapy with your doctor can be a worthwhile step towards a faster and potentially less invasive path to recovery. Remember, early diagnosis and appropriate treatment are key to optimal healing and regaining full function.
