SpF® Implantable Spine Fusion Stimulator

A Proven Treatment for Posterolateral Lumbar Spine Fusions

Proven Clinical History

  • Over 100,000 implanted to date
  • 50% increase in fusion rates over autograft alone(1)
  • Significantly improves fusion success rates particularly in patients with specific risk factors(1, 2, 3, 4)


  • In pre-clinical investigations, DC stimulation enhances the expression of several different osteoinductive growth factors, including BMP-2, BMP-6, and BMP-7(5, *)


  • Cost-effective, particularly in multi-level fusions
  • CPT and ICD-9 Codes
Providing a constant dose of electrical stimulation for approximately 6 months(6)
