    Dr. Corenman:

    Not certain if my first attempt at a question went through, so I will try again. I fell 20+ feet in November 2014. Bilateral zone II sacral fractures, transverse process fractures of L-5. On my CT scan they found bilateral pars fractures of L-5 also, which they believe were present before my fall. My sacral fractures healed well with some lingering nerve issues, however my back pain was unrelenting with radiculopathy and a non-union of the pars. The MRI showed grade I spondylolisthesis with a degenerative disk at L-5 which my surgeon believed was the pain generator. Stand-alone ALIF performed in August of 2015 with cage and graft. The initial plan on the day of surgery was a front and back operation, however my surgeon stated he felt he had the required stability with the ALIF only and did not proceed with the posterior stabilization. 7 months post-op and I am again experiencing significant pain directly over L-5. The pain is exacerbated when standing and any upon kind of physical activity. I also still feel a popping in the area as before surgery. Should I be concerned or just wait it out? Thank you!

    Return of pain at month 7 after an ALIF (anterior lumbar interbody fusion) could signal a pseudoarthrosis (nonunion). Stand alone ALIFs at L5-S1 without posterior support in the face of an isthmic spondylolisthesis has a higher nonunion rate. You could start with X-rays including flexion/extension films to see an obvious lack of fusion or can get a more definitive CT scan. I would investigate.

    Dr. Corenman:

    Thank you for the quick reply. I am quite apprehensive about scheduling another visit with my spine surgeon. I was very much hoping for a successful outcome after my surgery and a return to my active lifestyle, however I will follow up.

    You might need a CT scan to determine your fusion status. Please keep us informed.

    Dr. Corenman:

    At your suggestion, and after meeting with my spine surgeon, I did have new x rays and a CT scan. The results are not totally unexpected. The good news is that the interbody fusion at L-5 looks good. The bilateral pars defect has not healed at all however after 7.5 months. In addition my surgeon noted a posterior tilt of L-4 which is putting pressure on the L-5 pars defect. My understanding is that the pars defect alone should not be painful, but the tilt of L-4 might be problematic. I trust my spine doctor and I respect his opinion but I am not sure how to proceed. He has suggested a posterior approach to address the pars defect and a possible fusion of L-4 to correct the alignment. Again, I feel I have a truly excellent fellowship-trained orthopedic spine surgeon, I just dread the thought of a second spine surgery and multiple-level fusions. Any advice you can provide would be greatly appreciated!
