@lisajanec After a failed L4-S1 fusion April 2023 I also have a loose screw and was told it’s best to leave it alone . I finally had to get a Boston Scientific Spinal Cord Stimulator in January this year! After being in so much pain prior to installation I was 95% afterwards (felt amazing actually got to sleep in bed immediately after installation which I couldn’t do for 8 months) I occasionally used an air bed that I used to be able to go to Mayo in Minnesota. 4 days after stimulator was put in we boxed the air bed up and I bent to pick a magazine and pulled the wires loose (so much for a $78,000 surgery) I just had it redone 2 weeks ago they used leads the first time and paddles the second time, they just removed my staples and turned it on Thursday it still needs some more adjustments but I’m about 75% pain free.
