Dr. Corenman,

First, I thank you for the work you do as a doctor and with this website. I am sure you have done more good in the world than you’ll ever truly know.

I will give you some factual and brief background and then ask my question regarding surgery…

I am a 34 year old male in excellent shape. I am probably in better shape now than in my 20’s. I was a very athletic kid, competed in several sports and eventually settled on tennis. I competed collegiately in tennis at a high level. Have no recollection of back pain my entire life except for one acute incident when I went snowboarding when I was 18. Woke up the next morning with back pain and never went again in my life.

I currently work as a physical education teacher and tennis coach. 6 months ago I began having nerve pain down my right leg. Specifically the pain is along the L5 nerve root, buttocks, outer thigh, outer shin, top of foot and big toe. My big toe is numb most of the time I am vertical and the pain builds gradually and is relieved completely when I flex or sit. Went to the doctor and found out I have isthmic spondylolithesis at L5/S1. My S1 is a transitional segment where it looks more like an L6, it is described as partial lumbarization. There is a rudimentary disk between S1 and S2. I am not sure if there is movement at that level. My spondy is a grade I or II, the slip is about 25% anteriorly. Flexion/extension X-rays show it is stable. My MRI is completely normal from L4 disk up with no signs on degeneration. L5 is anterolisthesis due to bi-lateral pars fracture. L5 has diffuse disk uncovering and bilateral facet arthritis, central left/paracentral annular fissure, mild recess narrowing present bilaterally but more so on the left. Finally, significant neuroforaminal narrowing is present bi-laterally.

So in the past 6 months I have done the course of PT and still workout daily, have been seen by a movement specialist to see if any deficiencies are feeding into my spondy and there are not, have taken a course of oral steroids and have had 2 injections. One injection was an epidural steroid and the second was transforaminal and specific right to the exiting L5 nerve root. None of this has helped, in fact it has only progressed with time. I can walk about 20 minutes before I have to sit down and flex. As you can imagine this is significantly hampering my ability to work, especially on the tennis court.

I have seen several doctors and it seems as through I am approaching a surgical intervention. One doctors recommends decompression and posterolateral fusion, another an ALIF without posterior hardware. another an ALIF with pre-cutaneous posterior hardware and another a TLIF. The posterolateral with bone from my hip seems old fashioned and safe. The ALIF without posterior hardware doesn’t make any sense to me because I don’t think it will hold up. The ALIF with posterior hardware makes sense because I get reduction of my spondy but I worry about decompression because it is indirect and my fragment is still floating around back there. And the TLIF makes the most sense because I get the inter body fusion, removal of the fragment and guaranteed visualization that my nerves are decompressed. However, the doctors says he would fuse me in place during the TLIF because it is hard to reduce posteriorly with the screws and it increases the chances of nerve damage.

So my questions are what surgery would you recommend? How will my transitional segment play into this? And can you enlighten me on the benefits/drawbacks of reducing my slip? It makes sense that the ALIF will give me the best reduction as it is necessary for decompression and the doctors rational is to reduce my chances of ASD. The fusion in situ with the TLIF also makes sense especially since my body is used to it being there for a long time but I worry about increasing my risks ASD with it fused out of alignment.

Can you give me a little guidance. I would also be interested in your consulting services.

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.
