About the Device

Electrical Bone Growth Stimulation

When a bone fractures, the body produces naturally occurring electric fields surrounding and within the fractured bone segments to stimulate repair.   These naturally occurring internal electrical fields are a critical biological process necessary for bone to grow and heal normally.

The purpose in using a bone growth stimulator is to mimic the body’s own natural occurring signaling processes by the application of an external, electric treatment signal for patients who may be at a higher risk of not healing.

The Biomet® OrthoPak® Non-invasive Bone Growth Stimulator System

What is the OrthoPak Stimulator System?

The OrthoPak Stimulator System is a non-invasive, nonsurgical, medical device. The OrthoPak Stimulator utilizes a unique capacitive coupling technology that is designed to deliver a therapeutic, electrical treatment signal via a pair of disposable electrodes. The Soft-Touch® electrodes that accompany the system are lightweight and easily applied to the skin at the fracture nonunion site. The treatment signal operates at a low level frequency in which most patients don’t feel anything during treatment; however, some patients have reported feeling a slight, tingling sensation.

What is the OrthoPak Stimulator System?
  • The OrthoPak Stimulator System is easy to use, portable and battery operated.
  • It’s the smallest and lightest non-invasive bone growth stimulator on the market allowing patients to treat while going about their daily routine.1
  • The Soft-Touch® electrodes means less weight placed at the fracture nonunion site
  • Compliance monitoring consistently tracks your treatment progress.
  • Over 85,000 patients have been treated with the OrthoPak Stimulator System. 2
  • The OrthoPak Stimulator System is FDA approved and has more than 30 years of clinical use in improving patients’ lives.3

How it works

How does OrthoPak work?

The OrthoPak Stimulator System works by sending low level electrical impulses directly to the nonunion fracture site via a pair of disposable electrodes. Two lightweight electrodes are placed on either side of the fracture nonunion site and positioned 180 degrees apart from each other. The stimulator produces an electrical treatment signal in the area between the electrodes, which helps to mimic your body’s natural healing process.
