I had a 2 level l4-s1 fusion (PLIF) with BMP about 4 years ago. First the BMP overgrew and caused almost complete obliteration of nerve root. Now I have found out that one of the lower pedicle screws is fractured. I had been making great progress getting my life back --being able to walk and hike--until about 3 months ago when pain started to increase but in my good side! It is the first time in a couple of years that I kept wanting to sit or lay down with simple walking very small distances. I am very discouraged. They found the broken screw by chance when the xrayed for a small bowel test. Now my question is what have others experienced as far as symptoms and pain. I am interested to find out what was done about the broken screw and what kind of results have you had? Any thoughts would be appreciated!
