    Hi Dr. Corenman,

    I wanted to give an update and ask some more questions if you’d be willing to answer them. I received an L5-S1 fusion 8 weeks ago, but I’m experiencing the same type of pain as before surgery except worse, and I haven’t felt much improvement.

    I got scheduled for surgery because my new CT showed unhealed pars fractures and haloing around the screws like you predicted, so my surgeon said that the pain was likely being caused by the bone/screw interface. I wasn’t able to get a pars block but got a CT myelogram for a better look at the area. They performed a TLIF through the midline incision of my original surgery and found that my original screws were loose before they removed them. My x-rays at the 6-week post-op looked normal.

    Recovery was going fine until I was taken off hydromorphone, and now the most activity I can tolerate is short walks every hour using a walker. My current pain description is stabbing pain in the low back (just above the glutes and to the side of the spine close to the midline) with aching pain in the leg going down to the foot. It affects one side of my back at a time and the corresponding leg, but the right side hurts most of the time. Any physical activity involving the legs will exacerbate the pain. The pain will switch into the non-hurting side with certain movements like putting too much weight on that leg or lying on that side, or sometimes randomly while lying on my back without moving much. A strange symptom is that whenever my back pain is bad it gets rid of a separate pain issue in my pelvis (suspected pudendal neuralgia that started after surgery for pilonidal disease a year ago) but this might not be related.

    I’m wondering if you think my pain will improve with time or if it’s possible I’ve had a different pain generator all along. Since my pain worsened after a surgery at L5-S1 would that indicate that the pain is coming from there? Are there other possible sources of my pain that wouldn’t show on my images? Another thing I’m confused about is that my back pain is located an inch or two below the incision. My physical therapist says it’s the area of the SI joints; could this possibly be the pain generator? It might be too early to come to any conclusions, but I am worried because my functioning is still so limited by the pain.

    Thank you!

    Thank you so much, Dr. Corenman! I will make sure to get an updated CT and a diagnostic pars block at my next doctor. Would a fusion be more difficult than normal with the existing screws having to be removed? I am wondering because I live in a small city in Virginia, and the most experienced surgeons are a few hours away, but there are some surgeons nearby who perform fusions. I want to make sure my next procedure is the last one. Also, is TLIF the best approach for this case?
