Hello, I am a 42 year old female with ongoing back problems. I had disc decompressions surgery in Aug 06, then spinal fusion of L4-S1 Nov 2010. I am having pain again in my back hips and legs. with the feeling of bugs crawling on my lower outsdie part of my left leg and lower inside part of my right leg with pain in the back of my right thigh. The neurologist sent me for an MRI w/wo contrast and xrays. He said that nothing showed up on the xrays but there was something on the MRI, but not to be concerned. I just got a copy of the report and it says that there is 2mm anterolisthesis with minimal disc bulging at L3-L4 and little evidence of facet joint arthrosis. After contrast evidence of moderate amount of postoperative epidural fibrosis narrowing the thecal sac at L4-L5 and L5-S1. Compared to previous study L3-4 anterolisthesis is a a new finding. What does all of this mean and was the neurologist right in saying it is nothing to worry about. Right after telling me this he set up a myelogram of the lumbar spine. AliceFollow up:Due to continuing and worsening of pain in back, hip, and legs, with tingling sensation and loss of some feeling now, the neurologist sent me for a nerve conductor test and emg.  Studies show significant changes since surgery.  Insurance denied mylogram previously, so he is appealing and sending me again.  See what happens this time.Alice
As your problem suggests of anterolisthesis, I would advise you to not perform any kind of spinal extension exercise
