How EXOGEN works - Low Intensity Pulsed Ultrasound System (LIPUS)
EXOGEN is a portable device that stimulates the bone's natural healing process10. The unit has a small transducer which is placed on the skin above the broken bone and emits low-intensity, pulsed ultrasound (LIPUS) waves through the skin and soft tissue to penetrate the bone.
EXOGEN works at all stages of the bone fracture healing process:
- Early: The ultrasound waves encourage cells to remove cell debris and bacteria.14
- Middle: The pulses stimulate the bone marrow to produce immature bone cells and cartilage cells. These two types of cells are essential to bone regrowth.15,16
- Late: The pulsed waves stimulate the membrane around the bone to ‘seal up' the fracture, allowing immature bone cells to collect and grow17-20. The ultrasound signals also encourage the newly formed bone cells to mature more rapidly21-25.
