grade1 anterolisthesis of L4 on L5 S1 spinal fusion

In May 2009 I had a spinal fusion of L5 S1. Started out healing well and then around November I started with severe pain and spasms in my left buttock and down my left leg. Also burning and spasms in my lower back. Physical therapist changed me to water therapy and it helps for the time but not long term. Orthopedic surgeon wouldn't listen and I fianlly couldn't stand it any longer I went to the emergency room on 2/1. They took an x-ray and found a grade 1 anterolisthesis of L4 and degenerative facet changes.

What does this mean?

Thanks for any help... I am so tired of this...


  • You many have instability of your spine. Have you had your OS look at these x-rays? If you can, I would get another opinion.

    Best to you,


  • Grade 1 anterolisthesis is the lower level Grade (out of 5 Grades) of a forward slip of the vertebra. If you look up spondylolisthesis on this Spine Health site, there is a lot of information about it.

    I was told that people can and do live with this, but you will probably need to do excercises to strengthen your back and core stability muscles. I have been fighting my Grade 2 spondylolisthesis for a couple of years, and have just been told that I need a laminectomy and fusion to correct it because I now have severe stenosis on my cord and nerve roots.

    I would get some medical advice.
    Take care, and I hope that things work out well.

  • I would suggest making an appointment with another surgeon. You really need to have this evaluated by a fellowship-trained spinal specialist. It is probably responsible for the pain you have been feeling.

    When there is slippage, a nerve can become squished, or it can get kind of caught when the sliding occurs, and then it can be freed back up....it all depends on your instability.
  • Hi Ellen I had a spinal/lamenictomy 6/28/13 with hardware place L4 - L5 _S1- after surgery I developed foot drop and also
    had surgery to decompress the nerve, it has been 19 months since and no improvement, tried everything therapy tens unit etc. I started with pain July of last year down legs and my whole spine is cool burning, they sent me to pain management who has since just October did 4 injections and I am now have a spine stimulator implant on 4/17/15 I just went last week to Ortho surgeon and seen his PA they took Xrays and found all of this EXAM: (ORD 2215) SPINE LUMBAR MIN 4 VIEW -Accession #: 6189341
    PROCEDURE: Lumbar spine 3 views on 02/17/2015.
    HISTORY: Low back pain radiating into both legs. Previous lumbar
    fusion. This
    COMPARISON: 06/17/2014
    INTERPRETATION: Erect lateral views of the lumbar spine have been
    obtained in the neutral position and also with flexion and extension
    maneuvers. AP erect film has also been acquired.
    There has been a prior fusion of L4, L5, S1. A grade 1 anterolisthesis
    is present at L4-L5 and a grade 1 retrolisthesis of L5-S1. Neither
    spondylolisthesis is associated with additional motion with flexion or
    extension. A posterior fusion has been performed from L4 to S1 with
    transpedicular screws and posterior rods. There has been anterior fusion
    of L4-L5 with an interbody spacer. There are no signs of the fusion
    hardware having loosened or changed in position. No junctional
    spondylolisthesis has developed at L3-L4. There is some mild disc space
    narrowing at L3-L4, however, this is without interval change.
    IMPRESSION: Stable fusion of L4-S1. Grade 1 spondylolisthesis of L4
    anteriorly on L5 and L5 posteriorly on the S1 is without interval change
    when compared to 06/17/2014. No motion occurs at these levels with
    flexion or extension.
