Biomet® SpinalPak® Non-invasive Spine Fusion Stimulator System


  • In one clinical study for posterolateral fusions, the SpinalPak stimulator demonstrated clinical or radiological healing outcomes as high as 92.7%1,*
  • For lumbar spinal fusions, overall success rate (clinical and radiographic) was 84.7% in the Spinal Pak group vs. 64.9% in the placebo group (P=0.0043)1
    • In posterolateral fusions, the success rate was 89.1% in the SpinalPak group vs. 64.9% in the placebo group (P=0.006)1

Scientifically Proven

  • In one in vitro pre-clinical study, upregulation of multiple bone morphogenetic proteins (BMPs) was shown to occur with capacitive coupling (CC) stimulation in as little as 30 minutes of exposure with optimal upregulation occurring at 24 hours 2,**
  • In another pre-clinical study, capacitive coupling (CC) stimulation was shown to cause significantly higher levels of cellular proliferation than other electrical stimulation technologies, including combined magnetic fields (CMF) and pulsed electromagnetic fields (PEMF)3,**

An Established Product

  • Nearly 400,000 SpinalPak Stimulator Systems sold4
  • More than 30 years of proven clinical use5

Designed with Patients in Mind

  • Smallest and lightest electrical stimulation device on the market6
    • Lightweight electrodes weigh less than an ounce allowing for minimal weight around the fusion site, and can be comfortably worn under a brace
  • Compliance monitoring software – The SpinalPak stimulator contains embedded software that displays patient treatment data. This data may be downloaded to a health care professional’s computer for reviewing, storage or printout, via the use of the Patient Compliance Data Download Software7

*Represents the radiological or clinical success rate for posterolateral fusion separately. Radiological results P=0.013; clinical results P=0.088. P values for the clinical success rate between 0.05 and 0.10 show a trend toward statistical  significance.

**Although not indicative of human clinical results, outcomes from pre-clinical research have been implicated in various models of bone repair.
