Thank you.

Would that then mean pars fracture are removed and lamina is left in free floating ?

The inferior facets of L5 (along with the entire lamina) are “disconnected” from the pedicles of L5 by the bilateral pars fractures. When doing a “minimally invasive” approach, you do not have access to the center of the spine. The surgeon can remove the free-floating facets from the free-floating lamina but cannot remove the entire lamina as this approach from both sides will not allow access to the entire lamina. This then prevents access to removing the entire free-floating lamina-facet complex and the quantity of bone graft is significantly diminished.

As I have said before, the minimally invasive approach is more of a marketing tool. It is not minimally invasive as if you add up the length of the incisions and the dissection, the incision for “minimally invasive surgery” is almost twice as long as a minimally open procedure with a lesser success rate. Nonetheless, a good MIS surgeon can have a good result.

Thank you

Having a MIS TLIF with smaller retractable cage and no posterolateral fusion doesn’t sound like a good risk to take for the first surgery. Some MIS surgeons will use similar boomerang cage as you and are able to do posterolateral fusion. The surgeon I am speaking to does not.

When surgeons “sell” this MIS technique they are comparing it to the typical 4-6 inch incision and muscle stripping that goes along with open TLIF. The selling point is no muscle stripping, less pain, faster recovery and they have tracked loss of blood.

Most spine surgeons do not operate through a small incision like yourself for open TLIF. As a matter of fact, none of them do!

You are the best ! Thank you.

Many of the TLIF surgeons I know use this minimally invasive central incision. The comparisons by the MIS crowd use the old 8-12 inch incision statistics to “prove their point”. There is significant muscle stripping with the MIS technique (if they perform posterolateral fusions) as the only way bone will fuse is with exposure and grafting. If there is no stripping, how do they perform decompressions? The muscles that attach segment to segment attach along the lamina. In addition, these muscles will have no function after fusion. Ask yourself why they need to be preserved if they will have no function after fusion surgery.

Thank you.

The MIS surgeons have told me that the central incision of 4-6 inches strips muscles off bone.

How would two arthroscopic incisions through a tube on either side of spine cause muscle stripping ? Perhaps this only applies to MIS TLIF without posterolateral fusion.

I have honestly looked high and low in my area. Any surgeon that does open TLIF makes a 4-6 inch incision to get wide enough for posterolateral fusion and pedicle placement.

They say the difference between 2 inch incision and 5-6 inch incision really has no factor long term; it just effect the length of the recovery time, which could end up being a full year.

If you know of anyone in the Northeast that has similar method to your own please let me know. I need to stay close to home for this surgery unfortunately.

FORGOT TO ASK….

If MIS TLIF does not fuse how do you fix it ? Do you replace cage and do posterolateral fusion ?

I was reading some of your past comments on leaving cartilage behind and not fully clearing endplate and nucleus out of disc space; I suppose if I were to ask my surgeon about this they would get offended and think I was overanalyzing this ?

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.
