SpinalPak Electrodes Attached to Patient's Lower Back

About the Device

Electrical stimulation of the spine is the application of an external, electric treatment signal that helps promote the body’s own natural healing process following a spinal fusion. A spine fusion stimulator is sometimes used to help the body heal; especially if a patient has specific risk factors or an underlying medical condition that may compromise normal healing.


  • In one clinical study for posterolateral fusions, the SpinalPak Stimulator System 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 SpinalPak group vs. 64.9% in the placebo group (P=0.004).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,**

Product Features

How it Works 

The SpinalPak Stimulator System works by sending low level electrical impulses directly to the spine fusion site via a pair of lightweight, disposable electrodes. The electrodes are placed 2-3 inches on either side of the fusion sight. The stimulator produces an electrical treatment signal in the area between the electrodes, which helps to mimic the body’s natural healing process

Recommended Use

The SpinalPak Stimulator System is designed to deliver 270 days of continuous therapeutic treatment for 24 hours per day. The recommended daily therapeutic treatment is continuous for 24 hours. Basic safety precautions should always be followed, including removal of the device prior to showering, bathing or swimming.

Healing outcomes may vary due to health, activity, risk factors or other medical conditions the patient may have. Not all patients are candidates for this medical device, so it’s important to evaluate each patient prior to prescribing the device. Only a qualified healthcare professional can determine the appropriate treatment for each patient.

Frequently Asked Questions


Biomet®  SpinalPak®  Non-invasive Spine Fusion Stimulator System
