Hi Dr. Corenman,

1.) Can you please tell me approximately how long you usually wait to give a CT scan after surgery to check for fusion ? What kind of CT scan is it ?

2.) Also, I have been walking 2-3 miles/ day for exercise on sidewalk and pavement and it appears that I have trochanteric hip bursitis, right hip. Pain is under control when not walking, however I need to walk to rehab. DO you ever hear this from your patients ? Any suggestions on what to do ? I have been doing some swimming instead of walking for now.

Thank you !

Depends upon cervical vs. lumbar fusion. I assume you mean lumbar fusion. If BMP was used-5 months. If BMP was not used, 9 months. I always recommend a 64-128 slice scanner with 1mm cuts of only the fusion area. If L5-S1 was fused, the technician should collimate to only the L5-S1 levels.

If this hip pain is truly intertrochanteric bursitis, then an injection of steroid into the bursa should relieve the pain. This pain could also be referral pain from a nerve, so make sure of the source. There are also skin pads that contain a battery and can drive steroid contained in the patch into the bursa (iontophoresis) that can be used.

Thank you, as always, for the helpful info.

I had BMP used at L5,S1. My surgeon says 6 months before a CT scan. I am at 4 months now and wanted to get a CT done at 5. Do you think there would be that much of difference?

Can you please provide the name of the skin pad that drives the steroid into the bursa ?

It is hard to determine what is going on with my hip. If I put a lidocaine patch on the outer hip it takes away the pain so I am assuming it is bursitis, however I am now getting some groin pain and my right leg feels little heavy when I walk. I did not have this problem before surgery and really don’t know what to do with it. Seems like anything I try makes it worse! However, I really need to keep walking!

Please let me know if you have any other suggestions. I tried to stretch my groin and seemed to make it worse.

Thank you!

Sorry, just saw iontophoresis on your post.

Why would someone use this vs. a steroid injection ? I never got any relief from steroid injections!

If a lidocaine patch works on your outer hip region, this certainly can be greater trochanteric bursitis. If the steroid injection is not placed in the bursa, there is a good chance it will not be effective. The steroid iontophoresis patch uses electricity from a small battery to push the medication in with magnetism. I do not know the name of this patch but any good therapist should have access to it.

I have found that 5 months after fusion with BMP is the appropriate time for a CT scan but 6 months is certainly acceptable.

Thank you, this is very helpful info.

With regard to my TLIF surgery at L5.S1.

I had a bi lateral pars fracture. The right side (TLIF side) had facetectomy where I believe the right side pars fracture was also removed. However, the surgeon just used pedicle screws for left side never removing bone on left because I never had left sided back or leg symptoms. He said it could cause more injury if he were to perform left side facetectomy.

The right side back and leg pain is much better and the the right side of back feels smooth to the touch. However I’m now have left sided back pain, right above buttocks and it feels real knotted up!

Where do you believe this pain is coming from and how can I resolve it ? Is this common ?

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.
