You seem to have the most conservative method of fusion, which is the most sensible and proven.

The disturbing part of all of this is there are many large reputable spine clinics that I have spoken to that use the expandable tri-tranium cage for MIS TLIF and OPEN TLIF. Based on my research of the cage being recommended, it does seem to pack less bone and I never thought about it, but who wants the mechanical screw device growing in their spine.

The reasons given for the tri-tanium is that it can be made porous or with large holes on the sides for the bone to grow through. The justification for the expandable cage is to restore lordosis.

In addition the cage is steerable and can be place nicely at the front of the spine. I don’t know if BMP can be place in front of this cage or not.

Please let me know your thoughts. Keep in mind, there are not many surgeons that do what you do i.e. microscope, 2 inch incision, O arm, BMP (usually just used for revision), GPS screw placement. You are way ahead of the curve.

“The pain is not generated from the muscle but from stretching the collapsed annulus that is typical with all fusions for degenerative discs. If the disc height is not restored, there is less pain but less restored alignment.”

What did you mean by this ?

Also, what is osteolysis ?

Your argument for boomerang over expandable cage again makes logical sense. If the whole point of the TLIF is to fuse then why on earth would I want to use a smaller cage ? Do you happen to know the size of the bommerang cage ?

My surgeon tells me that the industry is moving away from peek cages and using tri-titanium for TLIF.

So I assume a long mid line incision through the back could generate residual pain and muscle stripping?

I have consulted with some top surgeons. None of them use microscope or O arm for open TLIF. They do an open incision and place pedicle screws with microscope glasses. Most do not use boomerang cage, some are moving to tri-tanium cage or expandable cages.

They all have a 4-8inch incision and is the reason for MIS TLIF.

In addition when it comes to BMP most surgeons are not well versed on where it goes and why. I had a surgeon tell me he would do a PLIF with two cadevor bones inserted in place of cage and put BMP in the middle and not on the sides. Does that sound right to you ?

Most surgeons do not communicate the way you do. They say one thing and then flip flop. They do not like to be questioned and when they are they always have a different way to do the surgery. Unlike yourself, where you have one set way and you do not deviate from what works for you.

You have a real passion for helping people. I appreciate your help.

Im not disagreeing with you, just letting you know what I’m hearing.

I believe the reason why surgeons warn about muscle stripping is because they make 4-8 inch incision in back. They say the need to get long enough to get wide enough. Whereas you have a two inch incision and use microscope.

Perhaps there is less recovery with your incision.

I would love to meet you someday. A lot of this is just common sense and I seem to follow your logic. I may have to fly all the way to Vail !

Thank you and I whole heartedly agree with all of your points.

With regard to muscle stripping, I sense that surgeons like to avoid open back surgery from a pain stand point. Most will say that muscle stripping or open incision is a long, painful recovery and residual scar tissue with midline incision can cause pain indefinitely.

Thoughts ?

many surgeons are now recommending MIS TLIF with BMP in a V shaped expandable cage for isthmic spondylolisthesis?

The thought is that there is less muscle stripping and lordosis is better with expandable cage, in addition BMP will fuse faster, however no posterolateral fusion.

I have read your previous comments about MIS TLIF and it is interesting to hear about the expansion mechanism causing endplate fracture.

Most surgeons would probably never admit to expansion mechanism causing fracture.

Do you still feel the same about MIS TLIF with BMP ?

Thank you

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.
