Active, implantable devices like 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 clinician before using the EXOGEN device.
EXOGEN has no known contraindications.
Yes, the actions of EXOGEN to treat nonunion† fractures are non-cavitating and nonthermal.44,45 Testing shows that it produces no untoward effects or migration of fixation.46 It is recommended to not place the transducer on top of fixation material, but to chose a different angle to reach the fracture, as metalwork will block the ultrasound wave.
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. For more information, download the EXOGEN Casting Application Techniques; or contact our local EXOGEN distributor or call Bioventus Customer Care.
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.
Tibia fractures up to 6.35 cm in length were healed in clinical trials using the EXOGEN system.2 The biological effect of the ultrasound beam spreads around the entire fracture by stimulating cells facing the transducer, by penetrating the bone to stimulate cells on the bone’s far side and by transmitting longitudinal and shear waves around the bone.41
In clinical evaluation, EXOGEN had a 92% success rate in treating nonunions of the femur,42 suggesting that EXOGEN is an excellent choice for patients with deep fractures.
The EXOGEN ultrasound beam expands to reach a width almost 2.5 times the size of the transducer. At its widest, the effective diameter of the ultrasound beam is more than 5 cm, and the therapeutic span is more than 3.4 cm—even after passing through 20 cm of soft tissue.39 EXOGEN ultrasound waves can penetrate through skin and soft tissue to reach bone up to 26.5 cm deep.43
EXOGEN is covered by most private insurers, as well as occupational health insurers. It is also possible that your hospital covers the cost for the device. It is of course also possible for the patient to pay for the device him-/herself.
