Elon Musk says ‘disc replacement’ worked for him. But evidence this surgery helps chronic pain is lacking

Last week in a post on X, owner of the platform Elon Musk recommended people look into disc replacement if they’re experiencing severe neck or back pain.
According to a biography of the billionaire, he’s had chronic back and neck pain since he tried to “judo throw” a 350-pound sumo wrestler in 2013 at a Japanese-themed party for his 42nd birthday, and blew out a disc at the base of his neck.
In comments following the post, Musk said the surgery was a “gamechanger” and reduced his pain significantly.
Musk’s original post has so far had more than 50 million views and generated controversy. So what is disc replacement surgery and what does the evidence tells us about its benefits and harms?
What’s involved in a disc replacement?
Disc replacement is a type of surgery in which one or more spinal discs (a cushion between the spine bones, also known as vertebrae) are removed and replaced with an artificial disc to retain movement between the vertebrae. Artificial discs are made of metal or a combination of metal and plastic.
Disc replacement may be performed for a number of reasons, including slipped discs in the neck, as appears to be the case for Musk.
Disc replacement is major surgery. It requires general anaesthesia and the operation usually takes 2–4 hours. Most people stay in hospital for 2–7 days. After surgery patients can walk but need to avoid things like strenuous exercise and driving for 3–6 weeks. People may be required to wear a neck collar (following neck surgery) or a back brace (following back surgery) for about 6 weeks.
Costs vary depending on whether you have surgery in the public or private health system, if you have private health insurance, and your level of coverage if you do. In Australia, even if you have health insurance, a disc replacement surgery may leave you more than A$12,000 out of pocket.
Disc replacement surgery is not performed as much as other spinal surgeries (for example, spinal fusion) but its use is increasing.
In New South Wales for example, rates of privately-funded disc replacement increased six-fold from 6.2 per million people in 2010–11 to 38.4 per million in 2019–20.
What are the benefits and harms?
People considering surgery will typically weigh that option against not having surgery. But there has been very little research comparing disc replacement surgery with non-surgical treatments.
Clinical trials are the best way to determine if a treatment is effective. You first want to show that a new treatment is better than doing nothing before you start comparisons with other treatments. For surgical procedures, the next step might be to compare the procedure to non-surgical alternatives.
Unfortunately, these crucial first research steps have largely been skipped for disc replacement surgery for both neck and back pain. As a result, there’s a great deal of uncertainty about the treatment.
There are no clinical trials we know of investigating whether disc replacement is effective for neck pain compared to nothing or compared to non-surgical treatments.
For low back pain, the only clinical trial that has been conducted to our knowledge comparing disc replacement to a non-surgical alternative found disc replacement surgery was slightly more effective than an intensive rehabilitation program after two years and eight years.
Complications are not uncommon, and can include disclocation of the artificial disc, fracture (break) of the artificial disc, and infection.
In the clinical trial mentioned above, 26 of the 77 surgical patients had a complication within two years of follow up, including one person who underwent revision surgery that damaged an artery leading to a leg needing to be amputated. Revision surgery means a re-do to the primary surgery if something needs fixing.
Are there effective alternatives?
The first thing to consider is whether you need surgery. Seeking a second opinion may help you feel more informed about your options.
Many surgeons see disc replacement as an alternative to spinal fusion, and this choice is often presented to patients. Indeed, the research evidence used to support disc replacement mainly comes from studies that compare disc replacement to spinal fusion. These studies show people with neck pain may recover and return to work faster after disc replacement compared to spinal fusion and that people with back pain may get slightly better pain relief with disc replacement than with spinal fusion.
However, spinal fusion is similarly not well supported by evidence comparing it to non-surgical alternatives and, like disc replacement, it’s also expensive and associated with considerable risks of harm.
Fortunately for patients, there are new, non-surgical treatments for neck and back pain that evidence is showing are effective – and are far cheaper than surgery. These include treatments that address both physical and psychological factors that contribute to a person’s pain, such as cognitive functional therapy.
While Musk reported a good immediate outcome with disc replacement surgery, given the evidence – or lack thereof – we advise caution when considering this surgery. And if you’re presented with the choice between disc replacement and spinal fusion, you might want to consider a third alternative: not having surgery at all.

How Stress Affects Your Body
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Sharon Bergquist gives us a tour:
Stress, from the inside out
Stress is a natural physical and emotional response to challenges or being overwhelmed. It can be beneficial in short-term situations (e.g. escape from a tiger) but is harmful when prolonged or frequent (e.g. escape the rat-race).
Immediate physiological response: cortisol, adrenaline (epinephrine), and norepinephrine are released by the adrenal glands.
The effects this has (non-exhaustive list; we’re just citing what’s in the video here):
- Cortisol impairs blood vessel function, promoting atherosclerosis.
- Adrenaline increases heart rate and blood pressure, leading to hypertension.
- Stress disrupts the brain-gut connection, causing:
- Digestive issues like irritable bowel syndrome and heartburn.
- Changes in gut bacteria composition, potentially affecting overall health.
- Cortisol increases appetite and cravings for energy-dense “comfort foods”.
- This in turn promotes visceral fat storage, which raises the risk of heart disease and insulin resistance.
- Immune-specific effects:
- Stress hormones initially aid in healing and immune defense.
- Chronic stress weakens immune function (by over-working it constantly), increasing susceptibility to infections and slowing recovery.
- Other systemic effects:
- Chronic stress shortens telomeres, which protect chromosomes. Shortened telomeres accelerate cellular aging.
- Chronic stress can also cause acne, hair loss, sexual dysfunction, headaches, muscle tension, fatigue, irritability, and difficulty concentrating.
So, how to manage this? The video says that viewing stressful situations as controllable challenges, rather than insurmountable threats, leads to better short-term performance and long-term health.
Which would be wonderful, except that usually things are stressful precisely because they are not entirely within the field of our control, and the usual advice is to tend to what we can control, and accept what we can’t.
However… That paradigm still leaves out the very big set of “this might be somewhat within our control or it might not; we really don’t know yet; we can probably impact it but what if we don’t do enough, or take the wrong approach and do the wrong thing? And also we have 17 competing stressors, which ones should we prioritize tending to first, and…” and so on.
To that end, we suggest checking out the “Want to learn more?” link we drop below the video today, as it is about managing stress realistically, in a world that, if we’re honest about it, can sometimes be frankly unmanageable.

Bone on Bone – by Dr. Meredith Warner
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
What this is not: a book about one specific condition, injury, or surgery.
What this is: a guide to dealing with the common factors of many musculoskeletal conditions, inflammatory diseases, and their consequences.
Dr. Warner takes the opportunity to address the whole patient—presumably: the reader, though it could equally be a reader’s loved one, or even a reader’s patient, insofar as this book will probably be read by doctors also.
She takes an “inside-out and outside-in” approach; that is to say, addressing the problem from as many vectors as reasonably possible—including supplements, diet, dietary habits (things like intermittent fasting etc), exercise, and even sleep. And yes, she knows how difficult those latter items can be, and addresses them not merely with a “but it’s important” but also with practical advice.
As an orthopedic surgeon, she’s not a fan of surgery, and counsels the reader to avoid that if reasonably possible. She also talks about how many people in the US are encouraged to have MRI scans for financial reasons (as in, they can be profitable for the doctor/institution), and then any abnormality is used as justification for surgery, to backwards-justify the use of the MRI, even if the abnormality is not actually the cause of the pain.
Noteworthily, humans in general are a typically a pile of abnormalities in a trenchcoat. Our propensity to mutation has made us one of the most adaptable species on the planet, yet many would have us pretend that the insides of people look like they do in textbooks, or else are wrong. The reality is not so, and Dr. Warner rightly shows this for what it is.
Bottom line: if you or a loved one are suffering from, or at risk of, musculoskeletal and/or inflammatory conditions, this is a top-tier book for having a much easier time of it.

Edam vs Gouda – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing edam to gouda, we picked the edam.
Why?
There’s not a lot between them, but there are some differences:
In terms of macros, their numbers are all close enough that one may beat the other by decimal place rounding, so we’ll call this a tie. Same goes for their fat type breakdowns; per 100g they both have 18g saturated, 8g monounsaturated, and 1g polyunsaturated.
In the category of vitamins, edam has slightly more of vitamins A, B1, B2, and B3, while gouda has slightly more of vitamins B5 and B9. A modest 4:2 win for edam.
When it comes to minerals, edam has more calcium, iron, and potassium, while gouda is not higher in any minerals. A more convincing win for edam.
In short, enjoy either or both in moderation, but if you’re going to choose one over the other, edam is the way to go.

Nutrition To Combat Lymphedema & Lipedema
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Kelly Sturm is a rehab specialist (Doctor of Physical Therapy), and also a certified lymphedema therapist. Here’s what helps her patients with lymphedema and lipedema:
Don’t fan the flames
Lymphedema and lipedema are inflammatory lymphatic diseases affecting mostly women. As such, an anti-inflammatory diet will be important, but there are other factors too:
- Anti-inflammatory diet: this is to reduce the chronic inflammation associated with lymphatic diseases. This means eating plenty of fruit and vegetables, especially berries and leafy greens, and avoiding things like sugar, alcohol, caffeine, and processed foods. And of course, don’t smoke.
- Intermittent fasting: this also helps by giving the body a chance to correct itself; when the body isn’t digesting food, it has a lot more resources to devote to its favorite activity: maintenance. This results in lower inflammation, and better fat redistribution.
- Weight loss: not a bandwagon we often get on at 10almonds as it’s rarely the most important thing, but in this case it is of high importance (second only to dealing with the inflammation), as excess weight around the lymph nodes and vessels can lead to dysfunction and swelling. Thus, reducing the weight can ease that and allow the body to heal.

Six Ways To Eat For Healthier Skin
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Sadia Badiei, the nutritionist-chef of “Pick Up Limes” fame, has advice:
More than skin-deep:
We’ll not keep them a mystery; here are the six points of focus:
1. Collagen and skin elasticity
Collagen is the structural protein that provides firmness and elasticity to the skin, but its production decreases with age, resulting in about a 1% annual loss starting at age 20. To support collagen, a diet rich in protein is essential, including foods like beans, lentils, tofu, tempeh, nuts, and seeds. They can’t do their work alone though; vitamins C and E play a critical role in collagen production and repair, protecting against damage from sun exposure, pollution, and free radicals. Vitamin E can be found in almonds, sunflower seeds, leafy greens, peanuts, and avocados, while vitamin C is abundant in citrus fruits, bell peppers, and broccoli.
2. Skin healing and zinc
Zinc is critical for wound healing and reducing inflammation, making it particularly helpful in managing skin conditions such as acne, eczema, psoriasis, and rosacea. Great dietary sources of zinc include nutritional yeast, pumpkin, sesame, and hemp seeds, as well as legumes and whole grains. However, zinc absorption can be hindered by phytate levels in some foods. Soaking, sprouting, or fermenting foods where possible can correct for that and improve zinc absorption.
3. Dry skin and hydration
Dry skin can result from many things, including dry air, hot water, abrasive soaps, and certain medications. While moisturizers provide external hydration, dietary omega-3 fats are essential for improving the skin’s barrier function, helping it retain moisture. Plant-based sources of omega-3s include walnuts, hemp seeds, chia seeds, flax seeds, and algae-based supplements. Staying adequately hydrated also supports overall health of course (everything runs on water in one way or another, after all), which indirectly benefits skin hydration, although drinking additional water only helps if dehydration is present.
4. Sebum regulation
Sebum, an oily substance that lubricates the skin, can cause issues like acne and blackheads when overproduced. Hormonal fluctuations and diet both influence sebum levels (in either direction). High glycemic index foods, such as sweetened beverages, refined grains, and sugary snacks, can lead to spikes in insulin, which in turn stimulates excess sebum production. In contrast, low glycemic index foods like vegetables, whole grains, tofu, nuts, and seeds regulate blood sugar and help manage sebum production, promoting clearer skin without an excess or a shortage of sebum.
5. Gut health and skin
The gut-skin connection means that imbalances in gut bacteria can contribute to skin issues like acne, eczema, and psoriasis. Supporting gut health involves increasing the diversity of beneficial bacteria through probiotic-rich foods. Fermented options like plant-based yogurts, kimchi, miso, sauerkraut, and kombucha not only improve gut microbiome health but also positively impact skin health by reducing inflammation and improving overall skin conditions.
6. Inflammation and skin health
Chronic inflammation is associated with so many health issues, and when it comes to skin, that includes acne, rosacea, and even wrinkles. Anti-inflammatory foods, especially those rich in antioxidants, can mitigate these effects and improve skin elasticity, smoothness, and color. Diets centered around fruits, vegetables, and other plant-based foods provide the necessary nutrients to combat inflammation, showcasing the significant role of nutrition in promoting radiant, healthy skin.

For Many Rural Women, Finding Maternity Care Outweighs Concerns About Abortion Access
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
BAKER CITY, Ore. — In what has become a routine event in rural America, a hospital maternity ward closed in 2023 in this small Oregon town about an hour from the Idaho border.
For Shyanne McCoy, 23, that meant the closest hospital with an obstetrician on staff when she was pregnant was a 45-mile drive away over a mountain pass.
When McCoy developed symptoms of preeclampsia last January, she felt she had the best chance of getting the care she needed at a larger hospital in Boise, Idaho, two hours away. She spent the final week of her pregnancy there, too far from home to risk leaving, before giving birth to her daughter.
Six months later, she said it seems clear to her that the health care needs of rural young women like her are largely ignored.
For McCoy and others, figuring out how to obtain adequate care to safely have a baby in Baker City has quickly eclipsed concerns about another medical service lacking in the area: abortion. But in Oregon and elsewhere in the country, progressive lawmakers’ attempts to expand abortion access sometimes clash with rural constituencies.
Oregon is considered one of the most protective states in the country when it comes to abortion. There are no legal limits on when someone can receive an abortion in the state, and the service is covered by its Medicaid system. Still, efforts to expand access in the rural, largely conservative areas that cover most of the state have encountered resistance and incredulity.
It’s a divide that has played out in elections in such states as Nevada, where voters passed a ballot measure in November that seeks to codify abortion protections in the state constitution. Residents in several rural counties opposed the measure.
In Oregon, during the months just before the Baker City closure was announced, Democratic state lawmakers were focused on a proposed pilot program that would launch two mobile reproductive health care clinics in rural areas. The bill specified that the van-based clinics would include abortion services.
State Rep. Christine Goodwin, a Republican from a southwestern Oregon district, called the proposal the “latest example” of urban legislators telling rural leaders what their communities need.
The mobile health clinic pilot was eventually removed from the bill that was under discussion. That means no new abortion options in Oregon’s Baker County — and no new state-funded maternity care either.
“I think if you expanded rural access in this community to abortions before you extended access to maternal health care, you would have an uprising on your hands,” said Paige Witham, 27, a member of the Baker County health care steering committee and the mother of two children, including an infant born in October.
A study published in JAMA in early December that examined nearly 5,000 acute care hospitals found that by 2022, 52% of rural hospitals lacked obstetrics care after more than a decade of unit closures. The health implications of those closures for young women, the population most likely to need pregnancy care, and their babies can be significant. Research has shown that added distance between a patient and obstetric care increases the likelihood the baby will be admitted to a neonatal intensive care unit, or NICU.
Witham said that while she does not support abortion, she believes the government should not “legislate it away completely.” She said that unless the government provides far more support for young families, like free child care and better mental health care, abortion should remain legal.
Conversations with a liberal school board member, a moderate owner of a timber company, members of Baker City’s Republican Party chapter, a local doula, several pregnant women, and the director of the Baker County Health Department — many of whom were not rigidly opposed to abortion — all turned up the same answer: No mobile clinics offering abortions here, please.
Kelle Osborn, a nurse supervisor for the Baker County Health Department, loved the idea of a mobile clinic that would provide education and birth control services to people in outlying areas. She was less thrilled about including abortion services in a clinic on wheels.
“It’s not something that should just be handed out from a mobile van,” she said of abortion services. She said people in her conservative rural county would probably avoid using the clinics for anything if they were understood to provide abortion services.
Both Osborn and Meghan Chancey, the health department’s director, said they would rank many health care priorities higher, including the need for a general surgeon, an ICU, and a dialysis clinic.
Nationally, reproductive health care services of all types tend to be limited for people in rural areas, even within states that protect abortion access. More than two-thirds of people in “maternity care deserts” — all of which are in rural counties — must drive more than a half-hour to get obstetric care, according to a 2024 March of Dimes report. For people in the Southern states where lawmakers installed abortion bans, abortion care can be up to 700 miles away, according to a data analysis by Axios.
Nathan Defrees grew up in Baker City and has practiced medicine here since 2017. He works for a family medicine clinic. If a patient asks about abortion, he provides information about where and how one can be obtained, but he doesn’t offer abortions himself.
“There’s not a lot of anonymity in small towns for physicians who provide that care,” he said. “Many of us aren’t willing to sacrifice the rest of our career for that.”
He also pointed to the small number of patients requesting the service locally. Just six people living in Baker County had an abortion in 2023, according to data from the Oregon Department of Public Health. Meanwhile, 125 residents had a baby that year.
A doctor with obstetric training living in another rural part of the state has chosen to quietly provide early-stage abortions when asked. The doctor, concerned for their family’s safety in the small, conservative town where they live, asked not to be identified.
The idea that better access to abortion is not needed in rural areas seems naive, the doctor said. People most in need of abortion often don’t have access to any medical service not already available in town, the doctor pointed out. The first patient the doctor provided an abortion for at the clinic was a meth user with no resources to travel or to manage an at-home medication abortion.
“It seemed entirely inappropriate for me to turn her away for care I had the training and the tools to do,” the doctor said.
Defrees said it has been easier for Baker County residents to get an abortion since the U.S. Supreme Court overturned Roe v. Wade.
A new Planned Parenthood clinic in Ontario, Oregon, 70 miles away in neighboring Malheur County, was built primarily to provide services to people from the Boise metro area, but it also created an option for many living in rural eastern Oregon.
Idaho is one of the 16 states with near-total bans on abortion. Like many states with bans, Idaho has struggled to maintain its already small fleet of fetal medicine doctors. The loss of regional expertise touches Baker City, too, Defrees said.
For example, he said, the treatment plan for women who have a desired pregnancy but need a termination for medical reasons is now far less clear. “It used to be those folks could go to Boise,” he said. “Now they can’t. That does put us in a bind.”
Portland is the next closest option for that type of care, and that means a 300-mile drive along a set of highways that can be treacherous in winter.
“It’s a lot scarier to be pregnant now in Baker City than it ever has been,” Defrees said.
