Use with Metal Fixation
The EXOGEN Ultrasound Bone Healing System is effective with all forms of fracture management in non-unions$% 1%$
Pre-clinical studies demonstrated EXOGEN◊ is:
- Safe – no untoward effects in the presence of metal implants2
- Non-cavitating – no pin migration or effect on a pin’s structural integrity3
- Non-thermal – detrimental thermal effects are not a concern4

The EXOGEN◊ Ultrasound Bone Healing System is indicated for the non-invasive treatment of established non-unions† excluding skull and vertebra. 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.
Contraindications: There are no known contraindications for the EXOGEN◊ device. Warnings and precautions pertaining to the treatment of either condition may be found at www.exogen.com or by calling 1-800-836-4080.
† A non-union is considered to be established when the fracture site shows no visibly progressive signs of healing. Rx only.
