How the Curves in Your Spine Cause Back Pain

By Dan Baumgard

Over 60% of us will suffer from lower back pain at some point in our lives. Without question, it’s the leading cause of disability across the globe.

Your spine is comprised of 33 bones known as vertebrae, which are stacked one on top of the other. The resulting column is divided into five segments: cervical (in the neck), thoracic (at the same level as the chest), lumbar (at the level of the abdomen) and sacral (connecting with the pelvis). The fifth, the coccyx, is located at the very bottom of the spine (the tailbone) – and is very painful when injured.

The vertebrae are connected by multiple joints, including discs which allow the spine to move in multiple directions. Though we might think the spine should appear straight, it naturally curves forward and backwards so it can perform all of its important functions.

But many conditions can cause the spine to curve more than it should. This can not only lead to pain, but potentially a whole host of other health troubles too.

Dowager’s Hump

The spine also supports the weight of the body, protects the spinal cord and helps the body to bend, flex and twist. The thoracic region attaches to the ribs and naturally curves backwards – this curve is known as the thoracic kyphosis.

But sometimes, the curve of the thoracic kyphosis becomes more accentuated and visible – often as a result of osteoporosis (where bones become weaker), age-related changes to the back muscles and vertebrae, or long-term poor posture.

The medical name for this condition is hyperkyphosis, though it’s sometimes referred to as “dowagers hump” as it’s around two to four times more common in women.

A stooped posture with rounded shoulders (or “hunchback” appearance) is typically a sign of hyperkyphosis.

In some cases, it may become so extreme as to impact breathing since the chest can’t inflate properly. It can also affect swallowing since the neck becomes more horizontal and the gullet potentially narrowed.

Dowager’s hump

And of course pain and stiffness typically arise. This is a common theme for most patients with abnormal curvature of the spine, as the vertebrae lose their ability to move, and nerves arising from the spinal cord can become compressed.

Scoliosis

Another type of deformity that can occur in the spinal column affects not only how it bends forward and backwards, but also side-to-side.

Scoliosis occurs when the vertebrae either curve sideways, rotate in relation to each other, or collapse. This produces a variety of different deformities, ranging in size and severity.

The underlying causes of scoliosis are widespread. Sometimes bones can become deformed as a result of trauma, cancer or an infection (such as tuberculosis).

Scoliosis can also be present from birth, or arise from neurological disorders in early years – such as cerebral palsy.

As well as back pain, patients may also notice postural signs as scoliosis evolves. Their shoulder blades or ribcage can stick out more, and clothes may fit differently on their body.

SCOLIOSOS

Slipped and Fused Spines

Individual vertebrae in any part of the spine can sometimes also become displaced as a result of trauma, wear and tear, or certain health conditions (such as osteoporosis).

This means that instead of standing in a regular stack, a vertebra slips forward, and out of line. This condition is given the long and practically unpronounceable name, spondylolisthesis.

In doing so, this displacement can trigger nerve compression. If the sciatic nerve – the largest in the human body – gets compressed, it can lead to symptoms of sciatica. These are namely pain, pins and needles, or numbness in the back of the leg or buttock.

The vertebrae in the lower back can sometimes also fuse abnormally together. A condition called ankylosing spondylitis can trigger inflammation in the spinal joints and discs, which then harden over time. Another name for the condition is bamboo spine, since the now rigid and inflexible column resembles a tough stalk of bamboo.

FUSED SPINE

Managing Back Pain

Managing these conditions – and the pain they cause – will depend largely on the size of the deformity and what has caused it in the first place. Even a small spinal deformity can be significant.

For scoliosis for instance, braces to correct the spine as it grows may work to manage small defects in younger patients. But corrective surgery is often required to fix larger deformities and those which don’t respond to bracing.

Taking account of posture and bone health can also help prevent developing a spinal problem later in life. Using exercise to build a strong back and shoulders and avoiding slouching are solid measures, too. Managing associated conditions such osteoporosis with diet, medication and resistance training can also help.

Surgical intervention may be required in other situations – for instance, to decompress nerves that have become trapped or squashed.

Your spine is truly an architectural wonder. It’s far from a straight and rigid column – and capable of more than you’d ever expect. But this unique structure can lend itself to problems, especially when natural curves become deformities. The age-old adage “strengthen your back, strengthen your life” is a motto we should all be regularly reminded of, and to seek medical advice accordingly should back pain arise.

Unnecessary Back Surgeries Performed Every 8 Minutes at U.S. Hospitals

By Pat Anson

Over 200,000 unnecessary or “low value” back surgeries have been performed on older patients at U.S. hospitals over the last three years, about one procedure every eight minutes, according to a new report.

The analysis by the Lown Institute estimates the potential cost to Medicare at $2 billion for unnecessary spinal fusions, laminectomies and vertebroplasties. The procedures either fuse vertebrae together, remove part of a vertebra (laminectomy), or inject bone-like cement into fractured vertebrae (vertebroplasty) to stabilize them.

Lown maintains that fusions and laminectomies have little or no benefit for low-back pain caused by aging, while patients with spinal fractures caused by osteoporosis receive little benefit from vertebroplasties.

“We trust that our doctors make decisions based on the best available evidence, but that’s not always the case,” said Vikas Saini, MD, president of the Lown Institute, an independent think tank that analyzed Medicare and Medicare Advantage claims from 2019 to 2022.  

“In spinal surgery, as with other fields of medicine, physicians routinely overlook evidence to make exceptions, sometimes at shockingly high rates. This type of waste in Medicare is costly, both in terms of spending, and in risk to patients.”

Up to 30 million Americans receive medical care for spine problems each year. While surgery is appropriate for some, the Lown Institute considers many common surgeries overused and of low value to patients. Potential risks include infection, blood clots, stroke, heart and lung problems, paralysis and even death.

Spinal fusions and laminectomies are considered useful for patients who have low back pain caused by trauma, herniated discs, discitis, spondylosis, myelopathy, radiculopathy and scoliosis. Fusions are also appropriate for patients with spinal stenosis from neural claudication and spondylolisthesis; and laminectomies are appropriate for patients with stenosis who have neural claudication.

Wide Variation in Overuse Rates

Nationwide, about 14% of spinal fusions/laminectomies met the criteria for overuse, while 11% of surgery patients with osteoporosis received an unnecessary vertebroplasty.  

The Lown Institute found a wide variation in overuse rates at some of the nation’s largest and most prestigious hospitals. UC San Diego, for example, had a 1.2% overuse rate for fusions and laminectomies; while the Hospital of the University of Pennsylvania had a 32.6% overuse rate.

The largest overuse rate was at Mt. Nittany Medical Center in Pennsylvania, where nearly two-thirds (62.8%) of the fusions and laminectomies were considered inappropriate or of low value.

The Lown report found that over 3,400 doctors performed a high number of low-value back surgeries. Those physicians received a total of $64 million from device and drug companies for consulting, speaking fees, meals and travel, according to Open Payments. Three companies — Nuvasive, Medtronic and Stryker — paid over $22 million to doctors who performed the unnecessary surgeries.

Previous reports by the Lown Institute have also questioned the value of procedures such as knee arthroscopies, a type of “keyhole” surgery in which a small incision is made in the knee to repair ligaments. Research has found that arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long-term.

The American Hospital Association takes a dim view of Lown studies, calling the data cherry-picked and misleading.

100,000 ‘Unnecessary’ Hospital Procedures Performed in First Year of Pandemic

By Pat Anson, PNN Editor

U.S. hospitals performed over 100,000 “low-value” procedures on Medicare patients in the first year of the Covid pandemic, including tens of thousands of spinal surgeries and knee arthroscopies, according to a recent study by the Lown Institute, a non-profit that seeks to reduce the use of unnecessary and ineffective medical treatments.

In 2020, no vaccines were available, the elderly were particularly vulnerable to the Covid-19 virus, and intensive care units were filled with infected patients. Yet many hospitals continued to perform questionable elective procedures at the same rate they did in 2019.

“You couldn’t go into your local coffee shop, but hospitals brought people in for all kinds of unnecessary procedures,” Vikas Saini, MD, president of the Lown Institute, said in a statement. “The fact that a pandemic barely slowed things down shows just how deeply entrenched overuse is in American healthcare.”

Lown researchers analyzed Medicare claims from U.S. hospitals for eight procedures that the non-profit considers to have “little to no clinical benefit” and are potentially harmful.  

Coronary stents were the most overused procedure, with over 45,000 balloon angioplasties performed to open up blocked arteries. The Lown Institute has long maintained that stents are unnecessary and risky in patients with stable heart disease.

Two spinal surgeries also made the list: 13,541 spinal fusions and 16,553 vertebroplasties were performed on older patients. In vertebroplasty, bone cement is injected into fractured vertebrae to stabilize the spine; while spinal fusions are used to join two or more vertebrae together to prevent them from moving and causing more pain. The Lown Institute considers fusions and vertebroplasties inappropriate for patients with low back pain and osteoporosis.

Nearly 1,600 knee arthroscopies were also performed in 2020, a type of “keyhole” surgery in which a small incision is made in the knee to diagnose and repair ligaments damaged by overuse or osteoarthritis. Recent independent studies have found arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long term.

“There are certain things, certain practices that are just insane. You shouldn’t be doing this. Nobody should pay for this,” said Saini.

Highland Hospital in Rochester, New York was rated as the top hospital in the country for avoiding overuse procedures. Richardson Medical Center in Rayville, Louisiana was ranked as the worst hospital.

The American Hospital Association disputed Lown's ranking system, calling it misleading.

"Throughout the pandemic, but especially in the early months, many nonessential services and procedures were put off due to government restrictions or voluntary actions from hospitals to make room for massive surges of COVID-19 patients," Aaron Wesolowski, AHA's VP of policy research, said in a statement to Becker’s Hospital Review.

"Studies have shown that these delays or sometimes even cancelations in nonemergent care have had some negative outcomes on the health and well-being of patients, who continue to show up at the hospital sicker and with more advanced illnesses. Many of these services may alleviate patients' pain or provide other help to patients. Lown may define these services as 'low value,' but they can be of tremendous value to the patients who receive them."

Epidural Steroid Injections Won’t Solve Your Back Pain

By David Hanscom, MD, PNN Columnist

A lawsuit was in the news recently about a Kentucky doctor who refused to give his patients pain medication unless they had epidural steroid injections.

Really? I have run across this scenario many times throughout my 32 years of performing complex spine surgery. It is a huge problem from several perspectives.

First of all, epidural steroid injections don’t provide lasting relief for any indication. This is particularly true when they are recommended for neck or back pain. There is not any research paper indicating a significant benefit. Yet they continue to be administered at a high rate.

I prescribed them sparingly for acute ruptured discs, where the natural history is for them to resolve without surgery most of the time. The steroids do knock down the inflammatory response that occurs around the disc material, so it buys some time and sanity while the body heals.

I also used them occasionally for spinal stenosis (constriction of the nerves). Pain in the arms and legs would usually improve for a short period of time.

What was unexpected was that many patients that I had on the schedule for surgery would cancel because their pain would disappear when they utilized other tools to calm down the body’s stress hormones. The more favorable hormone levels changed their pain threshold.

Epidural steroid injections as a stand-alone treatment might be of some benefit, but they aren’t going to definitively solve your chronic pain. Whatever benefit that a patient may feel probably comes from the systemic effects of the drug. Steroids make everything feel better, but it’s unfortunate that there are so many severe side effects.

Let me share what happened to one patient.

Ralph was one of my favorite patients. I worked with him for over 20 years. I haven’t met a more well-intentioned human being. By the time I first met him, he had undergone over ten surgeries and was fused from his neck to his pelvis. He never had relief from his chronic back pain. I had to perform a couple of major surgeries just to get him standing up straight.

I worked hard with Ralph on a structured rehab approach with some modest success. I lost track of the number of phone calls. He had a lot of stress at home and was helping to raise a grandchild. In spite of his pain, he kept moving forward.

Then he broke through and had a dramatic decrease in his pain and better function. Ralph wasn’t pain free and his function was permanently limited because his spine was fused. But he was stable on a relatively low dose of opioids. We were both pleased.

I didn’t hear from Ralph for many years until he called me from his local hospital. He was quite ill. His entire spine was severely infected. His primary care physician, who took care of his meds, had retired. No one else would take care of his needs and he was referred to a local pain clinic, which performed a high volume of spinal injections. They would only prescribe opioids if Ralph agreed to the injections.

Not only are injections ineffective for back pain, they really don’t work in the presence of 12 prior surgeries. Ralph’s back was a mass of scar tissue, rods and bone without much of a nerve supply. There is also less blood supply in scar tissue and a much higher chance of infection. Where would you even place a needle if the whole back is fused?

We admitted Ralph and had to open up his whole spine, which was infected with several hundred milliliters of gross pus. It took another two operations to wash him out and get the wound closed. He eventually did well, and we continue to stay in touch.

Ralph had to undergo a proven ineffective procedure in a high-risk setting in order to obtain pain medications that were effective. He became seriously ill, underwent three additional surgeries with the attendant pain and misery, and the cost to society was over a hundred thousand dollars. I rest my case.

Spinal Fusions Ineffective for Osteoporosis Patients

By Pat Anson, PNN Editor

There is little evidence that two surgical procedures commonly used to treat spinal fractures caused by osteoporosis reduce pain for patients better than pharmaceutical drugs, according to a new report by an international task force of bone health experts published in the Journal of Bone and Mineral Research..

More than 10 million Americans suffer from osteoporosis, a loss of calcium and bone density that worsens over time and significantly raises the risk of bone fractures, especially among the elderly. About 750,000 spinal fractures occur each year in the United States alone.

The task force looked at two types of spinal fusions: vertebroplasty, where medical grade cement is injected into the broken vertebrae to fuse bone fragments together; and balloon kyphoplasty, where a balloon is inserted into the compressed area of the spine to lift it and allow the cement to be inserted. Metal plates, screws and rods can also be used in spinal fusions, but were not the focus of the study.

The researchers found little to no evidence that vertebroplasty or kyphoplasty relieve pain effectively. In five clinical studies, vertebroplasty provided no significant benefit in pain control over placebo or sham procedures. There were no placebo-controlled trials for balloon kyphoplasty, leaving doctors to rely on anecdotal, low-quality evidence.

"The message for doctors and their patients suffering from painful spinal fractures is that procedures to stabilize spinal fractures should not be a first choice for treatment," said lead author Peter Ebeling, MD, Head of the Department of Medicine in the School of Clinical Sciences at Monash University in Australia.

"While patients who had these surgeries may have had a short-term reduction in pain, we found that there was no significant benefit over the long-term in improving pain, back-related disability, and quality of life when compared with those who did not have the procedures."

The task force report comes as spine surgeons increasingly market vertebroplasty and kyphoplasty as “minimally invasive" procedures that offer immediate relief from back pain without the risks of opioid medication. But there are still risks of infection, cement leakage and complications associated with elderly patients undergoing anesthesia.

Some 300,000 Medicare patients underwent vertebral augmentation between 2006-2014, with most getting the more expensive balloon kyphoplasty. The procedures have become so common they are recognized as a standard of care. The video below calls them "the most effective pain relieving treatments for elderly patients.”

"These procedures are not a magic bullet," says Bart Clarke, MD, President of the American Society for Bone and Mineral Health and a Professor of Medicine at the Mayo Clinic. “Until now, doctors have been left to sift through the data on their own to determine whether these procedures can benefit their patients. This report coalesces all that information concisely and provides recommendations to guide them."

Clarke said Mayo Clinic doctors do not typically perform vertebral augmentation procedures unless a patient's pain is unmanageable for more than 4-6 weeks. "We've seen that with analgesics and other pain relief, our patients often get better within about 6 weeks," he said.

The task force also focused on the need for osteoporosis prevention. About 25% of older men and women who have a hip fracture will have a second fracture within one year, as will around 20% of older patients who have a spinal fracture. Breaking a bone in your spine or hip may be so traumatic – especially for the elderly -- that it often leads to disability and chronic widespread body pain.

Recent studies have shown that many patients at high risk of fractures are not being diagnosed or treated for osteoporosis, even though hormones and bisphosphonate drugs can help strengthen their bones. Bisphosphonates such as Fosamax have been found to be effective at slowing the loss of bone mass and reducing fractures, but concerns about side effects made some patients reluctant to take bisphosphonates and doctors less likely to prescribe them.  

"Overall, prevention is critical. and we need to get these high-risk patients on anti-osteoporosis drugs that have proven to reduce future fractures by as much as 70 percent," Clarke said.
