    Hello Doctor Corenman. April 2013 I had ALIF at L5-S1 with instrumentation.
    Immediately following surgery, I had pain down both glutes / piriformas muscle to behind both knees into calf muscles. What has really struck me is the continuous vacillation of both calf muscles. All of the above not present before surgery.

    Subsequently, have had 2 contrast MRI’s, x’rays, and EMG. Both MRI’s show nothing of consequence. No focal disc herniation identified. Narrowing of the L4-L5 and L5-S1 neural foramen. The EMG indicated some interference at L5
    None these symptoms was present prior to surgery. I have been given lyrica which doesnt seem to help.
    I am convinced there is some nerve irritaion and would like to have this corrected.

    Am I being unreasonable? I am a very fit individual and always had an active lifestyle. This pain has progressed continuously since the surgery, and is starting to affect my physical/mental well being.

    Because of the artifact caused by the hardware, the MRI seems to be of little help. Is there any other way to determine if the nerves are irritated or compressed, and if so, what would you recommend for treating this?

    Much Appreciated.
    Doug.

    If you had an ALIF and then a posterior instrumentation (probably called “minimally invasive”), there was no decompression of the posterior nerves.

    I am not sure how you can get narrowing of the L5-S1 neuroforamen under the influence of an ALIF as the ALIF distracts the foramen (unless this surgery was performed for an isthmic spondylolisthesis in which case the ALIF can compress the roots with distraction. See the current pars thread currently active on the forum to understand this concept.

    What was the reason for the ALIF?

    MRI results Feb 11,2011. Grade2 anterolisthesis of L5 on S1 with bilateral pars interarticularis defects. Bilateral lateral neural foramen narrowing at this level.

    At L4-L5 minimal broad-based disc bulge with minimal compression on the anterior thecal sac and no significant central canal spinal stenosis and exiting nerve roots are spared. Remainder of the lumbar spine disc levels are also normal in appearance

    Dr. Corenman I hope the above explains the reason for the AlIf. Both procedures ie: fusion and instrumentation performed at the same time at the Cleveland Clinic in Ohio. It was explained to me that a spinal fusion was the only cure for my situation.
    Is it possible that this surgery has put more pressure on the exiting nerves? If so, can this be identified and subsequently relieved.

    I can’t thank you enough for your insight.

    Regards
    Doug

    If your symptoms warranted a fusion (and I imagine they did), then a fusion was the correct way to go. ALIFs are not a bad surgery but in the face of an isthmic spondylolisthesis, in my opinion, posterior decompression is also needed along with the posterior instrumentation. This is due to the bone spur that so typically grows off the pedicle in this disorder. The ALIF distracts the fused level which opens the foramen but does not remove the spur. Yes, surgery can put more pressure on the exiting nerves in this case.

    Dr Corenman….Thanks for the prompt response. Is decompression surgery a complicated process and is this something you would consider for me?

    Decompression surgery is a standard procedure and if your disorder warranted it, you could be a candidate for decompression. It depends upon your symptoms, your physical examination, imaging results and possible further testing such as selective nerve root blocks or other diagnostic testing.
