    I am confused. The solid interbody fusion at L5-S1 should alleviate all pressure on the pars defects which will not heal by themselves and never would have been suspected of healing with this surgery. The “tilt” of L4 should also not create any pressure on the pars defect with a solid interbody fusion at L5-S1. Remember that the pressure of the “tilted backwards” L4 vertebra loads the superior facets of L5. These facets-which were never part of the disorder (they are normal) attach to the pedicles of L5 which will transfer forces through the vertebral bodies through the fusion to the sacrum-totally bypassing the pars defects.

    I think you might consider a CT scan to determine the solidity of the fusion and any other problems that could occur.

    Dr. Corenman:

    I did have a new CT and Ext/Flex x-rays last week. Per my surgeon, the x-rays look “the same”. The CT did show that my fusion was “looking good”, but the pars defect was unchanged. I returned to my doctor for new axial back pain upon lifting/standing and he ordered the tests. The pain is centered directly over the lower lumbar spine at onset, and by the end of the day my entire low back is painful and stiff. When I can rest and lie down, my symptoms abate significantly. I am attempting to figure out what can be generating my pain. Based on your most recent reply, I can assume that the pars defects are not my pain generator? I guess its back to square one with diagnostic injections and the like! Very frustrating! Thank you for your advice!

    I am not sure what “the X-rays look the same” means. Does that mean there is no motion on these films or the motion “has not changed”? What does the radiological report note about the interbody fusion?

    Your symptoms sound to be pseudoarthrosis or level above breakdown. The pars defects will not cause pain in the face of a solid fusion.

    Isn’t it possible that if the pars defect was not removed that the bone spurs underneath the pars could still be compressing the nerves as you have stated in the past ??

    If the spurs are still present under the pars fractures, there is an outside possibility that the spurs could be irritating the nerve roots. However, if the vertebral bodies are fused, there should be no motion and therefore no ability to compress the roots even more than they already are. On the other hand, if there is a pseudoarthrosis present, then the roots could easily be irritated.

    In your opinion, if this patient were to have had this ALIF with pedicle screws and rods for back up (no posterolateral fusion) do you believe this is an acceptable surgery for grade one spondy.

    This has been suggested for me several times. This seems to be the surgery of choice for grade one spondy. ALIF 360 with minimal invasive screws and rods to hold the ALIF in place.

    Will fusing just the spinal column give enough support to go for a jog again ?
