How Smoking Can Cause Spinal Fusion Failure

How Smoking Can Cause Spinal Fusion Failure

Smoking killed my mom’s older sister, Aunt Bertha. Even now, so many years later, my mom still remembers with a hurt heart  my Aunt Bertha’s last days on Earth. Even as her face turned blue from the lost of oxygen and her lungs were dying, my aunt still wanted her cigarette. Her death was not peaceful. My aunt Bertha’s story is not unique, but fortunately  more people are becoming aware  that cigarette smoking is associated with an increased risk of lung problems. However, most people don’t know that smoking is also bad for your bones and can result in such things as spinal fusion  failure.

A Man Prepares For Surgery
Stop Smoking Before Surgery

Here Are Some Stats to Think About

Currently, there are more than 50 million smokers in this country, and approximately 800 billion cigarettes are smoked each year. Smoking is now the leading avoidable cause of morbidity and mortality in the United States. According to one report, over 500,000 deaths per year in the United States alone can be attributed to smoking[1]

However, how smoking can cause spinal fusion failure is also becoming a major issue for those needing back fusion surgery.

This post examines the issue in depth with the hope that if you or a loved one is in need of a spinal fusion surgery you understand completely  how smoking can effect  the outcome.

With that said, let’s jump in and discuss what exactly is spinal fusion surgery?

Spinal Fusion shown With Rods
A Spinal Fusion

In that procedure, surgeons remove discs between two or more vertebrae. The bones in the spine are then attached with hardware and treated with growth factors. As the spine heals, new bone begins to form, and the vertebrae fuse together.[2]

 

Orthopedic  Patients and Spinal Fusion Surgery

It’s becoming increasingly clear that orthopedic patients who smoke have worse outcomes than those who don’t. The clinical effects of  smoking on bone and wound healing include longer times to union, higher rates of nonunion, and higher rates of infection and wound complications.[3]

Here is an Illustrative Story of a Smoker With a  Spinal Fusion Problem.

“I had spinal fusion on L4/L5 with bone graph and cadaver bone. I’m almost 3 months post op. While I feel better I still have pain and have muscle spasms. My Dr. said my fusion is not fusing . My hardware is 4 screws and 2 rods. I did smoke until weeks b4 surgery and quit..well I started back (5 cigarettes a day)”—smoker from spinal fusion forum

In a study of more than 75,000 Canadian adults, daily smoking was associated with increased odds of having chronic LBP; this is consistent with the results of similar studies that were conducted in the USA [4]

At Jefferson Medical College/Rothman Institute, reviewed several studies that highlighted the effects of smoking on fracture healing, reconstructive procedures, and wound healing.

” Smoking is the only significant predictor of nonunion in open tibial fractures,” said Dr. Hilibrand. “Spinal fusion studies have found higher nonunion rates among smokers, compared to nonsmokers. [5]

 

3 factors That May Determine How Smoking Prevents Fusion of The Spine

  • Low Level of Vitamin D
  • Smoking reduces bone mineral content
  • Smoking accelerates spinal degenerative processes [6]

In the last post I covered how Vitamin D Deficiency can cause back pain. Well, researchers  have found that the main risk factors for inadequate   Vitamin D were smoking.There is now enough evidence that shows a link between low Vitamin D and poor outcomes following spinal fusion. In other words, the vertebrae didn’t fuse. The evidence is so strong that some doctors are recommending that patients having orthopedic surgery ensure they’re getting enough  vitamin D.

Smoking  Can Cause Spinal Fusion Failure by Reducing Bone Mineral Content

Smoking has been shown to adversely affect bone mineral density, lumbar disk disease, the rate of hip fractures, and the dynamics of bone and wound healing. I should point out that  scientific and clinical information on smoking and its consequences suggests differing degrees of correlation between smoking and orthopedic conditions. Some studies say there is a strong correlation and some say the correlation may not be impactful on some people. most available data however do suggest a real and reproducible relationship between smoking and slow bone healing. In a word, smoking makes it much harder for a spine to fuse.

Effect of Nicotine on Spinal Disc Cells: a Cellular Mechanism For Disc Degeneration

When studies confirm that smoking is a strong risk factor  for back pain, the most widely accepted explanations for the association between smoking and disc degeneration is malnutrition  of spinal disc cells. In other words, nicotine, a constituent of tobacco smoke, present in most body fluids of smokers may be the culprit  that prevents nutrients from reaching spinal disc cells. In essence, the bone graft does not get enough nutrients due to a lack of blood supply and, therefore, does not grow and cannot form a fusion.

Return-to-Work Study of Smokers Vs. Non-smokers

A study by Glassman, Anagnost et al. (200) investigated the effects of smoking and smoking cessation on spinal fusion out comes. As part of their analysis, they looked at the return to work rate in smokers versus non-smokers, all of whom had s successful spinal fusion surgery ( they had a solid fusion). The investigators found the following return to work rates:

  • 51% for patients who never quit smoking before or after surgery
  • 68% for patients who quit smoking for longer than one month after surgery
  • 77% for patients who quit smoking for longer than 6 months after surgery
  • 71% for patients who were non-smokers [7]

Conclusion

I don’t want anyone walking away feeling that this post offers a conclusive  connection between smoking and  lower back pain. The truth is that  few reports have demonstrated a definitive   relationship between  smoking dose and lumbar disk herniation (LDH), a cause of lower back or sciatic pain. There are other factors to  also consider such as how big, how tall, how strenuous  one works. One has to also look at the contribution of genetics to LBP. This post was focused more on the risk of smoking as it relates to spinal fusing. Smoking has been found to accelerate the rate of disc degeneration and this might contribute to ongoing spine problems even after a spine fusion. If you or a loved one is in need of spinal fusion surgery,  the doctor  may have to postpone the operation.   I present this information so that you or a loved one takes the time to stop smoking  before the due date of the operation and perhaps 6 weeks after the operation.

  1. Hello there,
    Thank god I am not a smoker:) Bit really was very interesting your article and i don’t understand how some people would continue smoking when their life is in danger when they are ready for a surgery…A good example your aunt:( I am really sorry for what happened to her, but a lot of people should read this information to understand the damage cigarets are creating.
    To be honest, I knew about lung problems, heart problems, skin…but not spine damages…Was really very helpful and thanks for sharing. I feel that you will help a lot of people here to quit smoking..to take care more about their health.

    1. Hi Christina,
      Thanks for your kind words. I’s so glad you found the post useful. Yes, a lot of people are aware of the heart , skin, and lung problems that smoking can cause. But they have no clue as to how smoking can damage their spine and bones. I’m glad you found this article useful. Always nice to hear from you.

  2. Very interesting! I have forwarded this post to my chiropractor.
    There are so many reasons not to smoke.
    I had no idea that this was one of them!

    1. Hi Dianne,
      A lot of people have no idea the damage that smoking can do to their bones. I’m glad you found this post useful.

  3. This is something I didn’t know about, I do know that smoking prevents many different problems when it comes to our body being healed. Especially the lungs. Good post.

    1. Hi Fred,

      First let me give you kudos for your own informative website. I have taken a look, and you have a lot of very useful information of how one can “live greater health”. As for smoking being bad for your bones, a lot of people don’t know that. This is why I wrote the post. If one is considering something like spinal fusion surgery, then one needs to know how smoking will effect the outcome. I’m glad you liked the post.
