Aging Population and Spine Health Statistics (2026): A Demographic Shift in Spine Care
The U.S. population over 65 is on track to double to more than 98 million by 2060, and spinal degeneration is nearly universal with age, present in over 90% of people over 50 on imaging. Together, these trends are reshaping the demand for spine care, even though degeneration and pain are not the same thing.
- The U.S. 65+ population is projected to roughly double from 46 million (2015) to over 98 million (2060), rising from 12% of the population in 2000 to a projected 20% by 2030.
- Disc degeneration appears in over 90% of both men and women over age 50 on imaging.
- Lumbar spinal stenosis affects about 45% of people over 60 and is the leading diagnosis for spine surgery in older adults.
- U.S. lumbar spine surgery rates rose over 200% since 1990 among adults over 60 with degenerative disease; Medicare spends over $1 billion a year on lumbar spine surgery.
- About 39% of adults over 65 have an osteoporotic vertebral fracture, a major and often underdiagnosed source of pain.
- Age alone is not a barrier to surgery: for appropriately selected patients over 65, mortality after degenerative lumbar surgery has been found no higher than the general population.
What's in This Report
1The Demographic Shift
America is aging quickly, and the spine is one of the parts of the body most affected by that shift. The proportion of the U.S. population over 65 is climbing from 12% in 2000 to a projected 20% by 2030, and in absolute terms the 65-and-older population is projected to roughly double from about 46 million in 2015 to over 98 million by 2060. The oldest group is growing fastest of all: those aged 85 and older are projected to reach 20 million by 2060, about three times the current number.
Because the prevalence of degenerative spine disorders rises with age, this demographic wave translates directly into rising demand for spine care. More older adults means more people living with age-associated spine conditions, and more people seeking both nonsurgical and surgical options to stay active and independent.

Explore the spine conditions we treat2How Common Spinal Degeneration Is
Spinal degeneration is one of the most common findings in the human body as we age, so common that it is nearly universal past a certain age. The population-based Wakayama Spine Study, using whole-spine MRI, found disc degeneration in 71% of men and 77% of women under 50, rising to over 90% in both men and women over 50.
A crucial nuance runs through all of this data: degeneration is not the same as pain. Many people with significant degenerative changes on imaging have no symptoms at all, and Medicare-based prevalence figures likely underestimate true rates because asymptomatic people are never diagnosed. This is exactly why imaging findings must be interpreted alongside a patient's actual symptoms, not in isolation.
Not necessarily. Disc degeneration is present in over 90% of people over 50, including many with no pain whatsoever. Finding degeneration on a scan does not automatically identify it as the pain source, and most degenerative spine conditions are managed without surgery. Matching the treatment to the true pain generator, confirmed by symptoms and exam, matters more than the scan alone.

Several distinct age-related spine conditions account for most of the pain and disability older adults experience. Many people have more than one at the same time, which makes accurate diagnosis essential.
| Condition | Key Statistic | Typical First-Line Approach |
|---|---|---|
| Degenerative disc disease | >90% over 50 (imaging) | Conservative care; injections if indicated |
| Spinal osteoarthritis (facet) | Over half of 40-59 (moderate-severe) | Conservative care; RFA for facet pain |
| Lumbar spinal stenosis | ~45% over 60 | Conservative care; decompression if progressive |
| Osteoporotic vertebral fracture | ~39% over 65 | Bone-health management; kyphoplasty/vertebroplasty if needed |
The progression is also gendered: the Framingham data found degenerative changes advancing 40% to 70% more often in women than men, consistent with the higher rate of osteoporosis and vertebral fractures in older women. Recognizing which condition, or combination, is driving a patient's symptoms is the foundation of effective, least-invasive-first treatment.

Explore interventional pain treatments4Rising Demand and Cost
As the population ages and degenerative conditions become more prevalent, utilization of spine care, both surgical and nonsurgical, has climbed sharply, and so has the cost to the healthcare system.
The U.S. has the highest rate of lumbar spine surgery in the world, and nonsurgical utilization has grown alongside it: between 1999 and 2009, lumbar epidural steroid injections rose by nearly 900,000 procedures per year and physical therapy evaluations by nearly 1.4 million visits per year. With the 65-and-older population still expanding, these numbers, and the associated Medicare expenditure, are projected to keep rising.
Two trends compound each other. The 65+ population is set to roughly double between 2015 and 2060, and degenerative spine disease prevalence rises steeply with age (over 90% disc degeneration past 50). Even holding per-person treatment rates constant, a doubling of the highest-prevalence age group implies a large, sustained increase in demand for spine care over the coming decades. That makes the efficiency of care, getting the diagnosis right and using the least invasive effective treatment, not just a clinical priority but a system-level one.

The encouraging news is that age by itself is not the barrier to good spine care that many older adults fear. When treatment is well-matched to the patient, outcomes can be strong even in later decades of life.
In a study of patients over 65 undergoing surgery for degenerative lumbar disease, mortality was actually lower than expected for the general population of the same age, particularly for women and those aged 65 to 84. Older patients do face higher risks of specific complications, such as postoperative delirium and longer hospital stays, which is precisely why careful patient selection, comorbidity management, and least-invasive techniques matter so much. Outcomes are best understood as reported ranges for appropriately selected patients, not guarantees.
Desert Spine and Pain is led by Dr. David L. Greenwald, MD, FACS, who is both a spine surgeon and a neurosurgeon. The practice's least-invasive-first philosophy, moving from conservative care and interventional pain procedures to minimally invasive surgery only when warranted, is especially well-suited to older patients, for whom reducing tissue disruption and recovery time can make a meaningful difference. Accurate diagnosis of the true pain source, rather than treating every degenerative finding on a scan, is the starting point.

While age-related degeneration cannot be fully prevented, its impact can be reduced: staying active, maintaining a healthy weight, not smoking, protecting bone health to lower fracture risk, and addressing pain early rather than letting it become chronic. If back or neck pain is limiting your life, an accurate diagnosis is the first step toward the least invasive effective treatment.

Methodology & Sources
How we compiled this report
All figures are drawn from Tier 1 primary sources: the U.S. Census Bureau, Medicare claims data, and population-based cohort studies indexed in PMC/NIH. Demographic projections come from U.S. Census Bureau population data as cited in peer-reviewed spine-care literature. Degeneration-prevalence figures come from population-based imaging studies, including the Wakayama Spine Study (whole-spine MRI) and the Framingham Study (serial CT), and from a Medicare claims prevalence analysis published in Scientific Reports. Utilization, cost, and outcome figures come from peer-reviewed analyses of U.S. and Medicare spine-surgery trends and cohort mortality studies.
Imaging-based degeneration prevalence reflects structural findings, which are common in people without symptoms; these figures should not be read as rates of painful or clinically significant disease. Some prevalence and utilization figures derive from specific study populations or time periods and may not generalize to all settings. Outcome figures describe study cohorts and are not predictions for any individual. Figures are rounded.
