Bone Growth Stimulator in Post-Injury Healing

Can bone growth stimulators help promote bone healing in cases where fractures or fusions fail to heal properly?

Bone Growth Stimulator

Individuals who sustain broken bones typically heal the fracture with appropriate treatment, which may include casts, realignment, and surgery. This type of surgery is performed on the spine and joints throughout the body; typically, the bone heals without a problem. Bone healing is a natural process, as bones are constantly replaced with new ones, and after an injury, the body can heal the damage to the bone. However, bone healing sometimes does not happen correctly and/or completely. Bone healing can take a long time, which is known as a delayed union, or it may not occur at all, or a nonunion. This is when a healthcare provider could recommend bone growth stimulation.

How They Work

Bone growth stimulators apply external or implanted electrical or ultrasonic energy to the fracture or fusion site, stimulating bone growth. These devices are often used when a fracture doesn’t heal within the expected timeframe (a nonunion fracture) or when a spinal fusion has not successfully fused. (FDA, 2022)

  • They come in various shapes, sizes, and technologies depending on the location of the fracture.
  • The most commonly used bone stimulators in orthopedics are electrical and ultrasound stimulators.
  • The stimulator emits a pulsed electromagnetic or ultrasonic impulse to the area where bone healing should occur.
  • Most modern bone stimulators are attached near the fracture site or fused with a small battery pack and worn for a period each day that may last minutes or hours.

Electrical Stimulation

  • Devices deliver low-level electrical pulses to the fracture site, which can stimulate bone cells to create new bone tissue.

Ultrasound Stimulation

  • They emit low-intensity pulsed ultrasound waves, which are absorbed by the bone and can promote bone healing.

Implantable vs. External

  • Some stimulators are surgically implanted, providing constant stimulation directly at the fracture site, while others are external and worn over the skin or cast.

The goal is to activate a series of receptors in the body to encourage a healing response. (Childs, S. G. 2003) The stimulator activates a pathway that releases chemicals within the body to promote fracture healing. This type of process in the body is called a cascade, and it happens when one signal stimulates another method, and so on until healing is complete. The bone stimulator ensures this cascade continues until the healing process is complete.

Effectiveness

Studies of bone stimulator effectiveness suggest two benefits:

  1. Less pain is associated with the bone healing process.
  2. Faster fracture healing.

However, these studies haven’t shown that these differences lead to improved patient functional outcomes. It would seem that if there is less pain and faster healing, then the patient should recover without complications. However, some researchers have suggested this is probably because the differences in pain and healing times are small and not necessarily noticeable. (Aleem, I. S. et al., 2016)

  • While bone growth stimulators can be effective, the results can vary, and their effectiveness is still under investigation.
  • Some studies have shown that stimulators can reduce pain and speed up healing time, while others have shown mixed results.
  • It’s important to discuss the benefits and risks of bone growth stimulation with a doctor to determine if it’s the right treatment option.

When Stimulation is Necessary

Bone stimulators are currently not used for routine fracture healing. It is certainly possible that bone healing stimulators will be used routinely in the future. They seem to show some benefit in non-healing fractures or fractures that are likely troublesome to heal. Some reasons individuals may have problems healing fractures are injuries to the blood supply to and around the fracture, injuries to specific bones, and overuse-related fractures. (Victoria, G. et al., 2009) These injuries may include (FDA, 2022)

Nonunion Fractures

  • When a fracture doesn’t heal within the expected timeframe.
  • Open fractures
  • Stress fractures
  • Scaphoid bone fractures
  • Talus fractures

Failed Fusions

  • When a spinal fusion hasn’t been successful.

High-Risk Patients

  • For individuals with factors that can hinder bone healing, such as smoking, diabetes, or certain medications

Bone healing typically proceeds without much problem. However, there are situations where people have issues healing after fractures or surgery. Bone stimulators are not used for routine bone healing but in situations where steps may be needed to help stimulate the body. While the improvement may be small, it may be critical if it is the difference between healing and nonhealing.

Scaphoid Fracture Causes and Recovery Insights

Individuals who have fractured their scaphoid bone may experience pain and swelling in the wrist just below the thumb. Can immobilization with a cast and physical therapy help?

Scaphoid Fracture

A scaphoid fracture is a break in one of the wrist’s small or carpal bones. This type of fracture occurs most often after a fall onto an outstretched hand. Symptoms typically include swelling and pain in the wrist just below the base of the thumb. These fractures can be difficult to diagnose since they don’t always appear on an X-ray. If the X-ray is negative and the healthcare provider suspects a scaphoid fracture, an MRI may be necessary. Surgery may be required in more severe cases or when the injury is not healing correctly. (American Academy of Orthopaedic Surgeons, 2023)

A Break In The – Navicular Bone

The scaphoid is one of eight carpal bones in the wrist. It is located just below the thumb’s base and is shaped like a kidney bean. This bone can be identified by holding a thumbs-up position and feeling for the hollow between the two tendons below your thumb. The scaphoid is located at the base of the hollow. A break in the scaphoid bone most commonly occurs in the middle of the bone but can also happen at either end. A scaphoid fracture can be displaced or non-displaced (American Academy of Orthopaedic Surgeons, 2023)

Displaced Fracture

  • It is when the bone fragments have moved out of alignment.

Non-displaced Fracture

  • It is when the fragments are still in their normal location in the hand.

The scaphoid’s blood supply comes from a small vessel that enters the most distant part of the bone and flows back through the bone. Because of this one small blood supply, a fracture in the center can stop the circulation to the proximal portion of the bone. Because of this, scaphoid fractures need immediate diagnosis and treatment.

Symptoms

Pain or deep aching on the thumb-side of the wrist, typically after a fall on an outstretched arm, could be a scaphoid fracture. Other symptoms experienced include: (American Academy of Orthopaedic Surgeons, 2023)

  • Tenderness at the base of the hollow area.
  • Pain at the base of the hollow area.
  • Swelling in the wrist
  • Difficulty gripping objects

Pain can become worse from: (American Academy of Orthopaedic Surgeons, 2023)

  • Grasping
  • Pulling
  • Pushing
  • Pinching

Diagnosis

A healthcare provider will evaluate the hand for tenderness and pain in the hollow and/or the bone. If a break is suspected, they will order an X-ray. (Clementson M., Björkman A., & Thomsen N. O. B. 2020) Many patients are diagnosed with a wrist sprain when they have a fracture. Diagnosis can be difficult because the fracture often doesn’t appear on X-rays until weeks after the healing process starts. Physicians commonly treat a wrist injury as a scaphoid fracture initially and then repeat X-rays within two weeks. (American Academy of Orthopaedic Surgeons, 2023) If the injury doesn’t show on an X-ray, the provider may order an MRI, as these fractures can be easier to see on an MRI. An MRI can help ensure appropriate treatment immediately. (Wong S. B. S., & Peh W. C. G. 2019)

Treatment

If a wrist fracture is diagnosed, the wrist will be immobilized in a cast. However, a healthcare provider may also put the wrist in a cast if the X-ray is negative but they suspect a fracture. This will stabilize the injury until an MRI can be performed. With immobilization and follow-up treatment, scaphoid fractures often heal without surgery. Repeat X-rays are taken over several weeks or months so the provider can make sure the injury is healing correctly. If it is not healing correctly, surgery may be recommended. (Clementson M., Björkman A., & Thomsen N. O. B. 2020) If the fracture is displaced, healing correctly may be a challenge. In this case, a physician may recommend initial surgery to reposition the bones. (Clementson M., Björkman A., & Thomsen N. O. B. 2020) This type of surgery involves pinning the bone in place with screws.

Healing Time

Recovery

With the wrist in a cast, individuals will be instructed on activities to avoid placing even a small amount of strain (American Academy of Orthopaedic Surgeons, 2023)

  • Lifting
  • Pushing
  • Pulling objects that weigh more than one pound.
  • Sports activities
  • Throwing
  • Climbing
  • Using tools or machinery that vibrate.

Rehabilitation is an important part of healing because immobilization takes a long time. Wrist range-of-motion exercises can be started, followed by strengthening exercises for the wrist flexors and extensors. Supination, pronation, and grip exercises are also part of physical therapy.

Complications

Scaphoid fractures can lead to serious complications, especially when not properly treated. These include: (American Academy of Orthopaedic Surgeons, 2023) (Almigdad A. et al., 2024)

Nonunion

  • This describes a fracture that fails to heal.

Carpal Collapse

  • This is a form of degenerative arthritis.

Osteoarthritis

  • This condition causes degeneration of the cartilage in the joint.

Avascular Necrosis

  • This is when the blood supply to the bone is reduced or cut off, causing the bone to die.
