Low Intensity pulsed ultrasound (LIPUS) is a treatment modality that assists in accelerating the formation of new bone at fracture sites.

The proposed mechanism is that the ultrasound waves stimulate a biochemical response with the bone which in turn stimulates bone growth.

This treatment needs to be done 20 minutes a day for several weeks to see results. Exact Physiotherapy hires out this machine for home use at $40/week.
