I was prescribed an Ortho fix after my fusion. My surgeon insisted on it. I used it as prescribed and I healed well. I think that it may make us heal faster but I also think that I would've healed without it, but I'm not a professional so I don't know! The Ortho Fix uses pulsed electromagnetic field therapy (EMF) and that is something that I'm not okay with. Electromagnetic fields are dangerous and are believed to cause cancer. Google "EMF". I stay away from electric blankets and anything that plugs in at night. Daytime is harder. So I strapped on this machine that puts an EMF right into my body for 6 weeks or so lol! If I had to use one again I think I would refuse.
