A Patients' Guide to Bone Growth Stimulation

Bone Growth Stimulation for Spinal Fusion Aftercare

Patient Guide to Bone Growth Stimulation

Spinal fusion may be included in surgical procedures to treat different spinal disorders. The goal of spinal fusion is to provide permanent stabilization of the spine. Fusion seeks to join and fuse two or more spinal bones—vertebral bodies—together to stabilize the spine. Spinal fusion is a healing process where vertebral bodies grow together and become solid.

  • Spinal Instrumentation
    Spinal instrumentation includes implants such as interbody devices, cages, plates, rods, and screws.
  • Bone Graft
    There are different of bone graft such as your own bone (autograft), donor bone (allograft), man-made (synthetic, bioengineered), and biologics (eg, bone morphogenetic protein [BMP]). Bone graft is packed into and around spinal instrumentation.

Bone Growth Stimulation
Your surgeon may prescribe a bone growth stimulator to promote and enhance your spinal fusion. There are different types of BGS devices.

  • Those implanted within the body (internal BGS).
  • External devices designed to be worn around the area of the spinal fusion (eg, neck or back).
  • The device emits low level electrical impulses that affect the bone-growing cells to induce bone healing and fusion.

BGS treatment typically is started soon after a spinal fusion procedure. Your surgeon understands that patients, and their postoperative needs differ. Therefore, he will recommend the type of stimulator appropriate for you and your needs.

"Bone growth stimulation for use in both the cervical and lumbar spine has shown to significantly benefit fusion results. Having been a study center for this technology, I have used bone growth stimulation in the majority of my post-operative cervical and lumbar patient cases. Not every patient is a candidate for bone growth stimulation. The patient evaluation criteria I use includes:
  • Patients who smoke
  • Multi-level fusions; more than one level of the spine is fused
  • Co-morbidities (risk factors) that could hinder bone healing and growth"
