Living with Osteoporosis: The Surprising Factors That Really Drive Fracture Risk

Please note: This article is for educational purposes only and does not constitute medical advice. Please always consult a qualified healthcare professional for any concerns about your bone health and fracture risks.

If you’ve been diagnosed with osteoporosis or osteopenia, chances are you’ve heard statistics like these:

• 1 in 2 women over 50 will break a bone due to osteoporosis — a risk greater than her combined risk of breast, uterine, and ovarian cancer.[^1]
• Worldwide, more than 37 million fragility fractures happen every year in people over 55 — roughly 70 fractures every minute.[^3]
• 24% of women over 50 who have a hip fracture die within one year.[^4]
• And if you’ve already had one fracture, your risk of a second one rises by 86%.[^5]

These numbers are real. They’re not made up to frighten you. And they are why organizations like the International Osteoporosis Foundation and the Bone Health & Osteoporosis Foundation take this issue so seriously.

But there’s something those statistics are not telling you — and it is currently transforming our perspective on what really drives our fracture risk.

The assumption built into most public messaging about osteoporosis is this: Low bone density is the primary driver of fracture risk. Protect your bones, slow your bone loss, raise your T-score — and your fractures will be prevented.

It is a logical and intuitive story. And it is significantly incomplete…

Bone Density Explains Only a Fraction of Your Individual Fracture Risk

What researchers have been discovering — in study after study, including some of the largest fracture investigations ever conducted — is that bone density alone explains only a fraction of who fractures and who doesn’t.

There are other factors at work. Factors that are:

· More predictive of fracture risk than bone density

· More predictive of fracture outcomes than the fracture itself.

· And factors that, unlike a T-score, respond powerfully to what you do every day.

In this article, we’re going to walk through three of the most important findings — discoveries that most women never hear about in a standard clinical appointment. By the end, we believe you will have a more empowered perspective on the many possibilities and options for fracture prevention available to you.

The Paradox at the Heart of Osteoporosis Research

Here is something that puzzles even doctors when they first encounter it:

For decades, researchers have known that low bone mineral density (BMD) is the most reliable and reproducible predictor of fracture risk we have available. Each standard deviation drop in BMD is associated with roughly a twofold increase in fracture risk — a magnitude of association that scientists compare to the relationship between high blood pressure and stroke.

That is a powerful statistical link. It is real, it is consistent, and it is why BMD measurement became the foundation of osteoporosis diagnosis worldwide.[^6]

And yet.

In a landmark study of nearly 10,000 women, 54% of those who had a hip fracture did not have osteoporosis. And a 2019 analysis published in the Journal of Clinical Endocrinology & Metabolism found that only 16% of fractures were directly attributable to low bone density — with osteoporosis and advanced age combined explaining only about one third of all fractures. Two-thirds of fractures, in other words, happened in people the system said were lower risk.[^7][6]

How can both of these things be true at the same time?

The answer lies in a critical distinction that gets lost in most clinical conversations: the difference between a risk factor and a cause.

BMD is a genuine risk factor for fractures. Lower BMD does mean higher risk — statistically, in large populations, on average.

But risk factors work at the population level. They tell us who is more likely to fracture across thousands of people. They do not tell us, for any individual woman, why she fractured or whether she will fracture.

Think of it this way. High blood pressure is one of the most powerful risk factors for stroke we know of. Yet many strokes happen in people with normal blood pressure — and many people with dangerously high blood pressure never have a stroke. Blood pressure is one input into a much more complex picture. BMD works the same way.

What fracture research is now revealing is that the picture has many more inputs than we previously appreciated — and some of them carry more predictive weight than BMD alone. Falls. Frailty. Neuromuscular function. Muscle strength. Balance. The ability to recover from a stumble before it becomes a fall.

These factors don’t show up in a T-score from a DEXA scan. But they show up — powerfully, consistently, and repeatedly — in the data on who fractures and who doesn’t.

That is what this article is about.

But I Have Osteopenia — Doesn’t That Explain It?

If you’ve had a fracture, or know someone who has, you may have heard this explanation: “Well, I had osteopenia — that’s why it happened.”

It’s worth taking a closer look at that.

Osteopenia simply means your bone density is lower than a 30-year-old’s — which, after menopause, describes the majority of women. It is not osteoporosis. It is not a disease. And the research on whether osteopenia alone causes fractures tells a nuanced story.

What the research now consistently shows is that fracture risk is shaped by many things at once — and bone density, whether osteoporotic or osteopenic, is just one of them. Factors like fall history, balance, muscle strength, coordination, medications, and overall physical frailty often carry more predictive weight than the DEXA-score alone.[^8]

The FRAX fracture risk calculator — used by doctors worldwide — reflects this exactly. It incorporates bone density, but also age, previous fractures, smoking history, medications, and other factors, because researchers know that bone density alone gives an incomplete picture.[^9]

The Greater Source of Fractures: More than 9 out of 10 Fractures Are Caused by a Fall

So what actually causes most fractures?

Here is the finding that changes everything: more than 95% of hip fractures are caused by falls.[^10]

According to the CDC, 88% of emergency room visits and hospitalizations for hip fractures in the U.S. are caused by falls. Every year, there are approximately 300,000 hip fracture-related hospitalizations in older adults — and the overwhelming majority trace back to a fall.[^11]

Think about that for a moment. We spend enormous energy focused on bone density — on T-scores and medication and DEXA scan results. And all the while, the thing that actually sends people to the hospital is the injuries that result from falling.

But here is where the story gets even more interesting — and more important.

It’s Not Just the Fall. It’s What Happens During the Fall.

Over 95% of hip fractures are caused by falls. But only 1–2% of falls actually result in a fracture.[^10]

Which means the fall itself is not the whole story. Something else is happening — something that separates the fall that leads to a fracture from the fall that doesn’t.

Researchers have studied this carefully, and what they found is that the direction of the fall matters enormously.

Falls that take a person directly sideways onto the hip produce fractures at much higher rates than falls in other directions. The height of the fall, how quickly the body is moving, whether the person was able to slow or redirect themselves, whether they could get a hand or arm out to absorb the impact — all of these factors determine whether a fracture occurs.[^10]

Which brings us to the insight that reframes the entire conversation:

“You didn’t fall because you tripped. You fell because you couldn’t recover.”

Your ability to recover from a stumble — to catch yourself, redirect, absorb impact, find your footing — is not determined by your bone density. It is determined by your balance, your reaction speed, your core integrity, your coordination, your muscle power, and your ability to sense and respond to your body’s position in space.

Those capacities are not measured on any scan. And they are not addressed by any medication.

But here is the genuinely wonderful news: they can be trained. At any age. With the right practice.

Beyond Falls: The New Research That Changes How We Look at Fracture Risks

We have saved the most important insight for this moment — because it is the one that most completely reshapes how we think about fracture risk.

It is not about bone density. It is not even, primarily, about falls. At the deepest level, what determines who fractures, who recovers, and who doesn’t — is frailty.

Frailty is a medical condition — it is a syndrome recognized and defined by researchers and clinicians — that describes a body that has started on a downhill decline. The five signature indicators of the frailty syndrome are: Unintended weight loss, muscle weakness, exhaustion, slow walking speed, and low physical activity. When three or more of these are present, a person is considered frail.[^12]

Over the last decade, large cohort and meta-analytic studies have confirmed that frailty is an independent predictor of fractures, over and above bone density.

A 2026 systematic review of 26 studies with more than 2.5 million adults aged 60 and older found that frail older adults had almost double the fracture risk of non‑frail peers (relative risk 1.95), while even “pre‑frail” adults had a significantly elevated risk (relative risk 1.28). Fractures increased not only at the hip, but also in the vertebrae and upper and lower limbs.

Similar findings emerge from large longitudinal cohorts. An analysis of over 400,000 participants in the UK Biobank reported that both pre‑frailty and frailty were associated with higher risks of total fractures, hip fractures, vertebral fractures, and other fracture types, even after adjusting for bone density and other risk factors.

Together, this research supports the idea that frailty—and the muscle weakness, slower walking speed, balance problems, and low activity levels that go with it—is a major driver of fracture risk, not just a consequence of fractures.

And what the research is now showing, in study after study, is that frailty is a far more powerful predictor of fracture outcomes than bone density, age, or almost any other factor we measure.

A 2025 meta-analysis — reviewing 15 studies and over 3,400 hip fracture patients — found that 4 in 10 hip fracture patients are frail. And among those with the worst outcomes, frailty was the dominant factor.[^13]

But a 2025 systematic review published in Frontiers in Medicine put the most precise numbers on it — and they are striking:

• Frailty increases the risk of dying in the hospital following hip fracture surgery by 3.2 times
• Frailty increases the risk of dying within 30 days by 3.9 times
• Frailty increases the risk of dying within one year by 1.5 times
• Frailty increases the risk of postoperative complications by 2.8 times
• Frailty increases the risk of delirium after surgery by 4.4 times
• Frailty increases the risk of pneumonia after surgery by 4 times
• Frailty increases the risk of hospital readmission within 30 days by 1.75 times[^14]

To put that in plain terms: a frail person who fractures a hip is nearly four times more likely to die within 30 days than a non-frail person with the same fracture. Not because their bones are weaker. Because their whole body is depleted — the reserves aren’t there to absorb the shock and recover.

We already know hip fractures are serious. One-year mortality rates following hip fracture range from about 6% in women in their 60s to nearly 20% in women in their 80s — and that’s on average, without separating frail from non-frail patients. When frailty enters that picture, those numbers get dramatically worse.[^15]

And here is a detail that is almost never mentioned in standard clinical settings: frailty doesn’t just affect what happens after a fracture. A 2025 clinical study found that frailty is strongly associated with a higher incidence of vertebral compression fractures and multiple fractures in older adults with osteoporosis — meaning frailty is connected to fracture risk as well as fracture outcomes.[^16]

Frailty, in other words, is not just a predictor of how badly a fracture ends. It is a predictor of whether you fracture in the first place.

One striking example of this shift comes from a Swedish research team that recently developed a hip‑fracture prediction model that can predict hip fractures independent of bone density. Using data from the entire Swedish population over age 50, they were able to accurately identify who would go on to have a hip fracture using 19 simple clinical variables—such as age, diagnoses like Parkinson’s or dementia, and whether someone needed home‑help services—without including bone density at all. The strongest predictors, beyond age, were markers of frailty and dependency: people receiving home‑help services had a five‑year hip‑fracture risk of almost 8 percent, even if they’d never had a DEXA scan.

Why Frailty Is the Real Story — and Why It’s Also the Most Hopeful One

Here is what makes the frailty story so important — and so different from the bone density story:

Frailty responds to movement in ways that no drug can replicate

…

Medication can slow bone loss. It can modestly reduce fracture risk in certain populations. But no medication in existence can rebuild the muscle strength, balance, coordination, reaction speed, and physical vitality that frailty erodes. Only movement can do that. And research consistently shows that the right kind of movement — progressive, targeted, whole-body training — can not only slow the progression of frailty but, in many cases, reverse it.

This is the bigger picture that a T-score will never show you. It is also the more empowering one.

Because it means the question isn’t just: “What is my bone density?”

The more important question is: “How resilient is my body? How capable? How ready to absorb, respond, and recover?”

And those are questions that movement — the right kind, with the right guidance — can answer in the most positive way possible.

What This All Means for You

Two-thirds of fractures are not caused by osteoporosis. Over 95% of hip fractures are caused by falls — and what determines whether a fall becomes a fracture is your body’s ability to catch and recover itself. And the deepest predictor of who fares worst after a fracture is not a bone density number. It is frailty — whole-body depletion — which responds powerfully to the right kind of consistent movement.

The best protection you have is not a scan result. It is a body that is strong, balanced, coordinated, and capable.

In our next article, we will go deeper into what that movement practice actually looks like — what the research says about the specific elements of exercise that build fracture resilience, and why a well-designed yoga practice for bone health may be the most complete approach available.

Because movement is not just an add-on to bone health. For most of us, it is the center of it.
