Sudden Back Pain After 65: Could It Be a Spinal Compression Fracture?

Sudden back pain after 65 can be a spinal compression fracture, a small collapse of a vertebra that is often linked to osteoporosis, sometimes after a minor cough, bend or lift. The pain is often felt in the middle or lower back and may worsen when standing or moving. Some fractures cause little pain. This article explains the typical signs, the red flags that need emergency care, how clinicians evaluate the problem, and what treatment can involve.

Sudden back pain after 65: what a compression fracture can feel like

The spine is a stack of bones called vertebrae. In a compression fracture, the front part of one vertebra can collapse, leaving it wedge-shaped. In older adults this is often associated with osteoporosis, a condition in which bones become thinner and more fragile. MedlinePlus describes osteoporosis as a condition that can make bones weak enough to break from a minor fall or, sometimes, from ordinary activity.

Features that may point toward a compression fracture include:

• Pain that begins fairly suddenly, sometimes after sneezing, coughing, bending, lifting or stepping off a curb.
• Pain centered in the middle or lower back that may feel sharp, deep or aching.
• Pain that can be worse when standing or walking and may ease somewhat when lying flat.
• Tenderness when pressing on the spine over one spot.
• Difficulty bending or twisting, or a feeling that the back is "locked."

Not every compression fracture follows this pattern. Some cause only mild or vague discomfort and may first be found on an X-ray taken for another reason. Pain that comes on without a clear injury is still worth mentioning to a clinician.

Why a spine can fracture with little force

Several factors contribute. Bone density tends to decline with age, and the vertebrae are made mostly of a spongy inner bone that can lose strength earlier than the dense outer layer. Menopause-related hormone changes can contribute in women; MedlinePlus covers this on its menopause page. Other factors that may raise risk include long-term corticosteroid use, a family history of fractures, smoking, heavy alcohol use, low body weight, low calcium or vitamin D intake, and some medical conditions. A clinician can review which of these apply to you.

Less often, a vertebra weakened by another process, such as cancer that has spread to bone, can fracture. This is much less common than osteoporosis as an explanation in an older adult, and back pain alone does not establish it. Clinicians consider it when the history or exam suggests it, for example with unexplained weight loss or a past cancer diagnosis. Back pain with a fever can sometimes reflect an infection in or near the spine, which is also uncommon but can press on nerves if it goes untreated. Back pain with fever, or back pain that is new or getting worse in someone with a cancer history, calls for evaluation in an emergency department the same day rather than waiting for a routine appointment, because delayed treatment can allow nerve damage. If leg weakness, numbness or loss of bladder or bowel control appears, call 911.

Compression fracture or an ordinary back strain?

Muscle strains and arthritis are common causes of back pain at any age, and our article on causes of lower back pain covers that wider list. Some clues can make a fracture more likely, though no single feature settles it:

• Pain that started suddenly in someone with known osteoporosis or risk factors.
• Pain after a minor fall or low-force event.
• Pain that is focused over one spot on the spine.
• Loss of height over time or a more rounded upper back, which may reflect earlier fractures.

Back pain can also come from organs outside the spine. If your back pain comes with digestive symptoms, see our article on bloating and lower back pain at the same time. Because causes overlap, clinicians combine your history, a physical exam and imaging rather than relying on the pain pattern alone.

Warning signs that need emergency care

Most compression fractures are painful but not immediately dangerous. A few presentations are different, because a fractured vertebra or another spinal problem can press on the spinal cord or the nerves below it. These need emergency evaluation:

• New weakness or numbness in a leg or both legs, or trouble walking that was not there before.
• New loss of bladder or bowel control, or being unable to urinate.
• Numbness in the groin or inner thighs (the "saddle" area).
• Back pain with a fever, or new or worsening back pain with a past or current cancer diagnosis, because infection or tumor near the spine can threaten the spinal cord. Go to an emergency department the same day.
• Severe back pain after a significant fall or accident, especially with a head or neck injury.
• Chest pain, shortness of breath, or sweating along with back pain, because heart and blood vessel emergencies can be felt in the back.

Severe, tearing back pain, fainting, or severe belly pain with back pain also needs 911, since a problem with a major blood vessel is possible. Details are in the emergency box below.

How clinicians evaluate a suspected spinal fracture

Evaluation usually starts with questions about when the pain began, any fall or injury, medicines (especially steroids), past fractures and other symptoms. The clinician examines the spine, checks strength, sensation and reflexes in the legs, and looks at how you walk.

Imaging commonly begins with an X-ray of the spine. If the X-ray is unclear, or if nerve symptoms are present, a clinician may order MRI or CT, which show more detail about bone and nearby nerves. Bone density testing and blood tests may follow to assess osteoporosis and other contributors. Which tests are right depends on your situation, so these are decisions to make with your clinician.

Treatment options and what recovery can involve

Many compression fractures are managed without surgery, and pain often improves gradually over weeks to months, though recovery varies from person to person. Care may include:

• Pain relief. Options a clinician may discuss include acetaminophen (Tylenol), other pain medicines, and short-term heat or cold. Acetaminophen has a daily limit on its label, and many cold and combination products contain it too, so a pharmacist can help you keep the total within that limit. Anti-inflammatory medicines such as ibuprofen and naproxen can raise the risk of stomach bleeding, kidney injury, and heart and blood pressure problems, and are not safe for everyone, particularly people with kidney disease, stomach ulcers, heart disease, or those taking blood thinners, so check with your clinician or pharmacist first. Opioids carry a boxed warning on their labels about addiction, misuse and breathing problems, and older adults can be more prone to drowsiness, confusion and falls. Muscle relaxants, sleep aids and other sedating medicines can raise fall risk as well, and a fall can cause another fracture. If one is prescribed, follow the prescriber's directions and ask them about safe storage.
• Activity guidance. Prolonged bed rest can weaken bones and muscles, so clinicians often encourage gentle movement as tolerated. A physical therapist can teach safe ways to move.
• Bracing. Some people are offered a back brace for a period. Evidence on its benefit is mixed, so ask whether it fits your case.
• Procedures. When pain is severe or does not improve, specialists may discuss procedures that stabilize the bone, or surgery in selected cases. Their benefits and risks vary and should be reviewed with a spine specialist.
• Treating the underlying bone loss. Medicines for osteoporosis, calcium and vitamin D review, and fall prevention can help lower the chance of another fracture. Please do not start, stop or change a prescription on your own; ask the prescriber.

Recovery after a different kind of fracture is covered in our article on recovery after a hip fracture in an older adult.

Possible complications

A compression fracture can lead to ongoing back pain, loss of height, a more stooped posture and reduced mobility. Multiple fractures may affect breathing capacity or appetite in some people. Having one vertebral fracture is associated with a higher chance of another, which is why evaluating bone health matters even after the pain settles.

Lowering the chance of falls and further fractures

• Ask your clinician whether bone density testing and osteoporosis treatment are appropriate for you.
• Discuss strength and balance exercises with a clinician or physical therapist.
• Remove loose rugs, improve lighting and add grab bars where the bathroom or stairs are risky.
• Tell your clinician or pharmacist about all your medicines, since some can cause dizziness or drowsiness.
• Talk with your clinician about calcium and vitamin D intake, and about smoking and alcohol use.
