Can patients with cardiac pacemakers or other active, implantable devices use EXOGEN?

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 physician before using the EXOGEN device.

Does EXOGEN have any contraindications?

EXOGEN has no known contraindications.

Can EXOGEN be used safely with metal fixation of nonunion fractures?

Yes, the actions of EXOGEN to treat nonunion fractures are non-cavitating and nonthermal.41,42 Testing shows that it produces no untoward effects or migration of fixation.43 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.

What do I need to do to prepare my patient for EXOGEN treatments?

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 in the cast. Our trained EXOGEN specialists will assist you with proper placement of the transducer port for casting and use with metals for nonunion fractures.

What does the EXOGEN unit include?

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.

Is EXOGEN able to treat the entire fracture?

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.44

Is EXOGEN treatment effective with deep fractures such as in the femur?

In clinical evaluation, EXOGEN had a 92% success rate in treating nonunions of the femur,45 suggesting that EXOGEN is an excellent choice for patients with deep fractures.

How effectively does EXOGEN penetrate soft tissue?

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.38 EXOGEN ultrasound waves can penetrate through skin and soft tissue to reach bone up to 26.5 cm deep.46

What is the process of bone healing?

The most common type of bone healing has four main stages. A broken bone starts to heal immediately after the injury, during the acute inflammatory phase. Next, your bone begins to develop new tissue at the ends of the fractured bone, called a soft callus. Over a period of the next two to three weeks, the soft callus is replaced with harder tissue, which is called a hard callus. The hard callus adds structure and strength to the newly formed bone tissue. Finally, your broken bone is remodeled to a fully functioning bone. Keep in mind that even after your broken bone has fully healed, the outer bone surface may be slightly swollen for a period of time.
