Axialif Revision

[donnac23]

Hello,

I had Axialif L5-S1 fusion 8/31/09. Back pain went away for about 10 months. Leg numbness remained, but was a bit improved. July-August, about a year later, back pain is back and intense, basically same as pre-fusion. I saw a new surgeon who said Axialif has a high-failure rate after the first 12-18 months, and I probably will need a revision. I have MRI and myelogram scheduled. He said the main screw is probably loose and the fusion probably did not complete on the inside.
Has anyone had an Axialif revision? What were your results? I also do not understand how the main screw being loose causes pain, if the outer area is fused. I'll have my test results in a couple of weeks. Overall, this is beyond disappointing.
