The Science Behind EXOGEN

Contact an EXOGEN Rep

The EXOGEN Bone Healing System uses FDA-approved safe, painless, low-intensity ultrasound waves to amplify your patient’s natural bone repair processes.

EXOGEN Mechanism of Action

Mechanism of Action

null
Stimulation36EXOGEN sends ultrasound waves through skin and surrounding soft tissue to reach the site of the bone fracture.
null
Activation37The ultrasound waves activate certain cell receptors, setting off a series of reactions, referred to as a cascade.
null
Upregulation38EXOGEN ultrasound increases upregulation of the processes critical to bone repair.
Check out Patient Case Studies

EXOGEN has multiple Level 1 and 2 clinical studies*1-3,5,17-35

*These studies, which reflect the body of evidence of the bone stimulator EXOGEN, include evaluations of applications outside the approved label. Assignment of evidence levels was based on the updated level of evidence rating system in the Oxford Level of Evidence Criteria.

Indications for Use

The EXOGEN Ultrasound Bone Healing System is indicated for the non-invasive treatment of established nonunions excluding skull and vertebra.
The EXOGEN device has also been reported as effective as an adjunctive non-invasive treatment of established nonunions in patients:

  • With internal or external fracture fixation hardware present. EXOGEN cannot penetrate metal and therefore should not be applied directly over hardware.
  • Undergoing treatment for infection at the fracture site. EXOGEN is not intended to treat the infection.
  • Believed to have diminished bone quality. EXOGEN is not intended to treat diminished bone quality.

In addition, EXOGEN is indicated for accelerating the time to a healed fracture for fresh, closed, posteriorly displaced distal radius fractures and fresh, closed or Grade I open tibial diaphysis fractures in skeletally mature individuals when these fractures are orthopaedically managed by closed reduction and cast immobilization.

There are no known contraindications for the EXOGEN device. Safety and effectiveness have not been established for individuals lacking skeletal maturity; pregnant or nursing women; patients with cardiac pacemakers; on fractures due to bone cancer; or on patients with poor blood circulation or clotting problems. Some patients may be sensitive to the ultrasound gel.

A nonunion is considered to be established when the fracture site shows no visibly progressive signs of healing
