SpF® Implantable Spine Fusion Stimulator

Providing a Proven Solution when Medically Necessary

With the continued pressure from insurance carriers, hospitals, and other paying parties to reduce costs, the SpF® Implantable Spine Fusion Stimulator may help to reduce the overall costs associated with posterolateral lumbar spine fusion surgery by increasing the probability of fusion success rates, particularly in patients with specific risks.


  • Cost-effective, particularly in multi-level fusions
  • CPT and ICD-9 Codes

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, Direct Current (DC) stimulation enhances the expression of several different osteoinductive growth factors, including BMP-2, BMP-6, and BMP-7(5, *)
Providing a constant dose of electrical stimulation for approximately 6 months(6)
