in reply to: MRI scans and signal #7247

I am unclear as to what has an increased signal. Is it the spinal cord? Cord signal changes are worrisome as this may indicate some prior injury to the cord and potential future injury.

Long tract signs (signs of cord irritation) are hyperreflexia, Hoffman’s sign (see website for description), clonus, balance and incoordination signs (Rhomberg’s, adiadochokenesis, imbalance with quick direction changes, triangle test).

Read the radiologist’s report of the MRI findings. You might find some valuable information there. You might also get another consultation for more information.

in reply to: SI Joint: Update and Question #7246

Joints are typically filled with synovial fluid and are distensible. This means that no matter what the position of the joint, there is always synovial fluid that fills the entire joint. When the joint (or disc space for that matter) wears out, there will be certain positions that increase the joint space that the synovial fluid cannot fill. This will create a vacuum and something has to fill that vacuum.

What fills the vacuum is nitrogen gas. This gas is pulled out of solution similarly to opening up a can of soda and watching the gas bubbles form out of the liquid.

Good luck with the surgery. Please report your progress to allow forum members to see your progress.

The approach side for the neck does not matter regarding which side the pathology is on regarding the spine itself. There are general factors that decide which approach side the surgeon prefers.

One is the anatomy of the neck. There is a very small nerve called the recurrent laryngeal nerve. This nerve supplies the vocal cords and there is one on each side of the neck. On the left side, the nerve consistently does not cross the surgical field. On the right side, the nerve crosses the surgical approach dissection about 5% of the time.

Interestingly enough, spine surgeons choose the left sided approach almost all the time and neurosurgeons choose the right sided approach most of the time. You can almost be sure that a spine surgeon performed the surgery by the left sided scar on the neck.

Previous surgeries in the neck require some prior preparation. Scar can make the dissection more difficult. If there has been a significant prior neck surgery or prior radiation treatment (for cancer), I will have my Ear Nose Throat (ENT) colleague assist me with the surgical approach. Ask your surgeon if this is something he would consider. The ENT surgeon typically has experience with these type of revision neck surgeries and should be able to safely dissect out the scar and gain access to the anterior neck.

Posterior decompression and fusion can be effective but is typically less effective than an anterior surgery and takes much longer to heal.

in reply to: previous C4-5 discectomy with fusion. #7235

Sorry about the delay. I responded to you but the return post must have become lost in the ether.

After a near fatal MVA and the need for a one level ACDF, there were probably other non-surgical neck injuries that after some years start to become more degenerative.

“Mild bone marrow edema is present at superior endplate of c7. there is a cord signal abnormality at c7 level consistent with degeneration”. Bone marrow edema is typically associated with significant degenerative disc disease and is commonly a neck pain generator. Cord signal change is typically an injury to the cord from compression. Why the radiologist called it “consistent with degeneration” does not make sense to me.

The cord does not typically “degenerate”. Normally, stenosis or narrowing of the canal causes cord compression and signal change but the radiologist notes the worse canal narrowing is at C3-4 and C5-6; “canal stenosis and mass effect on the cord”. The MRI report does not make much sense to me. Maybe the radiologist misdictated the levels.

Your arm pain could be generated by compression of the right C6 or C7 nerves; “c5-6: annular disc bulging posterior ligamentous hypertrophy resulting in mild canal stenosis and mass effect to cord with bilateral moderate to severe neural foramina narrowing.
c6-7: right paracentral disc protrusion resulting in right neural foramina narrowing. posterior ligament and hypertrophy”

Nerve blocks can be valuable to reduce symptoms until a surgical procedure can be performed. I do not think that RF (radio-frequency ablations of the facet nerves) would be valuable.

By the way, I have two PAs, both named Eric (one spells his name Ehrich).

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!
