Summary of Indications for Use
EXOGEN is indicated for the non-invasive treatment of osseous defects (excluding vertebra and skull) that includes the treatment of delayed unions, nonunions,* stress fractures and joint fusion. EXOGEN is also indicated for the acceleration of fresh fracture heal time, repair following osteotomy, repair in bone transport procedures and repair in distraction osteogenesis procedures.
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.
Full prescribing information can be found in product labeling, at EXOGEN.com, or by calling Bioventus Customer Service.
*A nonunion is considered to be established when the fracture site shows no visibly progressive signs of healing.

Summary of 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 orthopedically 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.

Frequently Asked Questions
Indications for Use
EXOGEN is indicated for the non-invasive treatment of osseous defects (excluding vertebra and skull) that includes the treatment of delayed unions, nonunions,* stress fractures and joint fusion. EXOGEN is also indicated for the acceleration of fresh fracture heal time, repair following osteotomy, repair in bone transport procedures and repair in distraction osteogenesis procedures.
EXOGEN has no known contraindications.
Fracture Treatment
Yes, the biological effect of the ultrasound beam goes around the entire fracture by shear waves.61
EXOGEN ultrasound waves can penetrate through skin and soft tissue for an effective penetration depth of ~10 inches (254 mm).61
Active, implantable devices such as cardiac pacemakers may be adversely affected by close exposure to the EXOGEN device. Patients or other people in close proximity during treatment should be evaluated by a cardiologist or physician before using the EXOGEN device.
Mark the fracture location on your patient. The EXOGEN transducer must be in direct contact with skin, so if your patient needs or currently has a cast, you’ll need to build in a transducer port or create a window. Our trained EXOGEN specialists will assist you with proper placement of the transducer port for casting and use with metals for nonunion fractures. For more information, download the EXOGEN Casting Application Techniques or contact Bioventus Customer Service.
EXOGEN Device & Coverage
The EXOGEN unit consists of the main operating unit and the attached cable with transducer head. Patients also receive an application strap, coupling gel, and battery charger.
Some insurers cover the EXOGEN device. For more information, contact your local EXOGEN representative or contact Bioventus Customer Service.

The Science Behind EXOGEN
The EXOGEN Bone Healing System uses safe, painless, low-intensity ultrasound waves to amplify your patient’s natural bone repair processes.
EXOGEN Mechanism of Action
EXOGEN has multiple Level 1 and 2 clinical studies*1-3,5,13-31
*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.

For Providers
Many patients have difficult-to-heal fractures or fractures they want to heal more quickly. EXOGEN offers a non-surgical option that helps to heal nonunion fractures and accelerates indicated acute fractures, so your patients can resume active lifestyles.*1-3
EXOGEN is a low-intensity pulsed ultrasound (LIPUS) bone stimulator with over 25 years of proven non-invasive bone healing. Prescribed by more than 10,000 physicians annually to help over a million patients worldwide, EXOGEN has an 86% nonunion heal rate and accelerates the healing of indicated acute fractures by 38%.1-4,12
EXOGEN makes treatment compliance tracking convenient for your patients and verifiable for you, with a built-in treatment tracking calendar.
See the Results in the Data
The EXOGEN Ultrasound Bone Healing System is like no other. It is the only FDA-approved device with 38% accelerated healing of indicated acute fractures.1,2
Outcomes with EXOGEN:
Accelerated healing in cortical and cancellous bone:
- 58 days and 37 days faster, respectively1,2
- Fracture healing promoted 41% to 51% faster in patients who smoke9
Accelerated healing of indicated fresh tibia fractures in younger and older patients1,48
- 42 days and 84 days faster, respectively1,48
Discover the noninvasive choice for resolution of nonunions. In clinical studies, low-intensity pulsed ultrasound waves helped heal nonunion fractures.
EXOGEN is effective:
- In chronic nonunion fractures that failed to heal at least one year prior to treatment – 86% heal rate3
- In atrophic, hypertrophic, or infected nonunions25,37,49
- With challenging, established nonunions – 86% heal rate3
- With high-energy nonunion fractures – 89% heal rate7
- For use on nonunions with an interfragment gap up to 10 mm and stable osteosynthesis15
