I went thru a whole year of surgeries due to a fibula non union fracture about 2 inches above the ankle. I also had bone grafting done too. The doctor ordered a bone stimulator and I used it 2 times a day, for about 4 months......fantastic results, unit was about $5,000, but workers comp paid for it all, I have a $300,000 lower left leg. This is how th first doctor screwed up my leg. He told me it was 90 to 95% healed and never showed me a xray. I came unglued when I found out how he screwed me up. I had gotten to the point I was wanting it amputated, 2nd doctor fixed the mess, took all of 2011, cost my carreer as a aircraft mechanic since now I have major nerve damage and that is mostly the problem, This is it fixed.
