Hello Doctor:
Thank you or this great website. I am 4 months post a PLIF on L5-S1 for spondylosethesis. I have had a long, painful recovery. My surgeon has indicated everything on my X-rays, MRI and CT post-op looks fine. One item I didn’t understand on my post-op MRI was “anteriolesthesis of L5-S1 – 5mm”. Pre-op, my MRI read I had spondylosethesis of L5-S1 of 5mm. I did not get a thorough review of my post-op MRI. When I asked him about the anteriolesthesis, he said “they got most of the slip, but there was a little residual”. Reading these two test results together, it sounds like the slip is the same – and I am very concerned. I am having significant back, glute, and leg pain. Thank you very much for any thoughts.

In surgically fusing a spondylolisthesis, there is generally no need to “pull the vertebra back” to perfect alignment. In fact, this reduction of the slip can be detrimental. The L5 nerve root contracts (shortens) over time with this slip and pulling the vertebra back can stretch the root. This in turn can cause root dysfunction (pain, paresthesias and even weakness).

I would read the radiological report carefully as you should be feeling much better at this point. How have you symptoms changed since surgery? Do you have new or more intense pain or is your pain unchanged?

Hi Doctor,
Thank you so much! Also have “mild diffuse disc bulge” at L1-2, L-3-4, stable mild degenerative disc space narrowing and changes at various levels, osteophytic spurring, mild scoliosis. Modic end plate change at L2-L3. My pain is worse than it was before surgery, and much more constant. The leg/glute pain has been particularly bad. I sit for long hours at work, which is very painful, even though I get up and walk every so often. I get a shooting pain in my lower right back pretty frequently. My surgeon says everything post-op looks as it should. Thank you so much for your assistance. I hope I made the right decision to have the fusion, but I am beginning to have doubts. Thank you again!

It is not normal to have worse pain than before surgery. In a case like yours, a new MRI or CT (or both) would be recommended.

Hi Doctor,

I just received my CT result. I am concerned that maybe a screw is misplaced and the nerve is compressed. Do you have any opinion or thoughts on the following quote:

Transpedicular screws are present bilaterally at L5 and S1 which appear centered
in the pedicles. The tip of the left L5 screw appears to project approximately 1
mm beyond the lateral cortical margin of L5 vertebra. Metallic clips are seen at
the L5-S1 disc space. A clip on the right lies in the region of the right L5-S1
neural foramen and could be associated with mild neuroforaminal narrowing.

Thank you very much for your thoughts so far. I am having a hard time interpreting the medical terms.

The screw placement most likely is not an issue. The statement: “Metallic clips are seen at the L5-S1 disc space. A clip on the right lies in the region of the right L5-S1 neural foramen and could be associated with mild neuroforaminal narrowing” might be concerning. This metallic clip might be the marker for the PEEK cage location. If it is in the foramen, this cage could be impinging on the right nerve root (L5).

Is your leg pain located on the right side? If so, I would suspect the cage is a problem.

Successful pars repair at 46 years old

Back in November of 2018 (at 46 years old) I came from Vancouver BC to have a pars repair done with Dr. Donald Corenman at the Steadman Clinic in Vail Colorado. I'm finally posting this review nearly three years later in late 2021. The reason I waited so long was I wanted to know the final result before I posted my review. Unfortunately in that time Dr. Corenman has retired. Nevertheless, I want to post this review of Dr. Corenman and his staff at the Steadman Clinic in their excellent treatment of my L5 pars interarticularis.

I fractured my pars at age 42 back in 2014 when rolling on the gym floor, and was denied treatment by the Canadian healthcare system, probably due to my age. First my GP told me there was no surgical option for a pars defect, which was quite incorrect! I tried to live with it, but the symptoms worsened (periodic random spine slippage and weeks of resultant pain after just bending over to tie my shoe, so I eventually learned to mostly squat and hardly bend). When I finally consulted with Canadian spine surgeons, I was told they believed my pars defect had been congenital (since birth). This was absurd, considering I had done extreme martial arts (including jiu jitsu) for years prior, as well as 5 years of reinforcing steel full time in my 20s, probably the hardest job on the back you can find. No pars defect like mine would possibly have allowed this--ergo it was impossible that I had had the defect since birth. I did however have an asymptomatic congenital spina bifida occulta that made me more susceptible to a pars fracture. In 2014 in one instant, I went from having the strongest back people I knew said they'd ever seen, to being unable to safely bend over and tie my shoe without a non-negligible risk of my spine slipping randomly (which would lead to weeks of pain after each occurrence). This was due to the unilateral L5 pars defect, otherwise known as spondylolysis. It was when lying in pain on the floor 4 years later after maybe the 6th spine slippage event post injury, that I had had enough, and resolved to have surgery. If Canada's "universal health care" said no, I would make lemonade from lemons, and find the very best surgeon in the world at pars repairs. That was Dr. Donald Corenman. Dr. Corenman back in 2018 ran a website https://neckandback.com/ that dedicated many pages to the science of every aspect of pars repairs, from eligibility (good discs on MRI), to best surgical techniques (minimal open compared to minimally invasive), best imaging to use (i.e., O-Arm with Stealth imaging vs. older fluoroscopy), the ideal amount of BMP to use and why not use too much or too little, and much more, all to do with pars repairs, pages upon pages of his site just on the pars, with scientific references and his own extensive expert opinion. As a health research statistician, I was very impressed with this. It was in stark contrast to the websites of other spine surgeons which barely gave the pars a word or two, focusing almost exclusively on fusions. I had found the best surgeon in the world for pars repairs, and so after Dr. Corenman personally screened my MRI to ensure my discs were healthy, I booked the surgery.

Being 46 years old at the time of surgery in 2018, with a 4-year-old pars fracture from 2014 combined with a congenital SBO meant my pars fragment was somewhat atrophied, but it was "very solid", said Dr. Corenman in the operative report. Nevertheless, it was challenging with two things to fix, the pars and SBO, and OR time was around 4 hours. Recovery over the following months was guided by a very clear "Spine binder" from the Steadman Clinic with strict rules of "no BLT" (no bending, lifting or twisting), and illustrated physiotherapy guidelines. They even warned patients to avoid fish oil supplements, which could excessively dampen inflammation and hence slow bone healing. They answered many questions I had during months of recovery, with responses coming from the very supportive Lori Fugate (then director of Dr. Corenman's practice), and Ehrich Bean (then physician's assistant at the practice), as well as a couple calls with Dr. Corenman himself after two of the CT scans. Ehrich Bean offered great advice for taking the spine binder conservatively due to the nature of pars repairs vs. fusions. The final post-op CT scan I had was a couple weeks ago at 34 months post-op, and Dr. Corenman had retired, but I got a very positive and informative call from Eric Strauch (current PA at the Steadman Clinic under Dr. Corenman's replacement there, and who had also worked with Dr. Corenman previously). The staff at the Steadman Clinic were extremely supportive all the way through the process. I should mention, the local Canadian spine surgeon did offer me very good post-operative support including antibiotics as needed to deal with a mild surface incision-site infection early on, booking numerous x-rays when I felt something was amiss, as well as booking all four of my post-op CT scans. I am very grateful for that support also.

My final result shows plenty of solid bone across the pars and a healed SBO, with my vertebral body now a solid bone ring instead of being broken at two places as it was pre-op. Does my spine hold up in the real world? You bet! I have recently dug and moved several yards of dirt and sand and gravel by myself (shovel and wheelbarrow!) to fix our water main, pulled roots from the yard, moved several "portable" (these are HUGE) air conditioners up several flights of stairs my myself, and lifted weights. I now run 2 miles (3.2 KM) several times weekly with a hard 100 meter dash in the middle. I bend deeply before each run I go on, with no spine slippage. My spine feels amazing. I can bend over to do exercise, or real word tasks, with no risk of spine slippage.

My sincere thanks to God, Dr. Donald Corenman, Lori Fugate, Ehrich Bean, Eric Strauch, and the Steadman Clinic, as well as the Canadian spine surgeon who offered me excellent post-operative care back in Canada. You have all given me a new lease on life.

Sincerely,
Eric S

Back Fusion Surgery

I had my entire lumbar spine fused in November of 2018. I had scoliosis , with pinched nerves that were so painful I could hardly walk - and standing for more than a few minutes was impossible. Even sitting was painful.
The fusion surgery produced immediate relief! And the recovery was much easier than I expected.
To this day I can do all the activities I love from hiking, to standing in a stream fly fishing to riding my bike long distances - or just walking down the street with my wife.
Kudos to Dr. Corenman and his staff, (including the two Erics) for taking such good care of me!

TLIF

I had my TLIF surgery on 6/24/2020 by Dr. Corenman, I can not say enough good things about the Dr or his staff. I was always treated with respect and explained everything throughly, that made it easy for everyone to understand. I highly recommend Dr. Corenman and the Steadman Clinic.
