Vertebral Compression Fractures: Osteoporosis, MRI Findings, and Treatment Options
A vertebral compression fracture is a collapse or “squashing” of one of the bones of the spine, often related to osteoporosis, trauma, or less commonly tumor or infection.
If your X-ray, CT, or MRI report uses words like “height loss,” “wedging,” “acute fracture,” “chronic compression deformity,” or “marrow edema,” it is normal to feel worried. The key question is not just, “Is there a fracture?” The better question is, “Is this fracture new or old, stable or unstable, and does it match your symptoms?”
Many vertebral compression fractures improve without major surgery. But some need closer evaluation, especially when there are nerve symptoms, major trauma, infection signs, cancer history, or severe pain.
What Is a Vertebral Compression Fracture?
A vertebral compression fracture is a collapse of the vertebral body.
The vertebral body is the front, weight-bearing part of a spinal bone. It is shaped like a block. When it compresses, it may look shorter, squashed, wedged, or partly collapsed.
This is different from a slipped disc, which is a common phrase for a disc problem. A disc is the cushion between spinal bones. It is also different from a disc herniation, where disc material bulges or leaks out, and from spinal stenosis, which means narrowing around nerves or the spinal cord.
Compression fractures are common in the thoracic spine, which is the mid-back, and the upper lumbar spine, which is the lower back. The area where the thoracic and lumbar spine meet is a common location.
In my practice, the first thing I explain is that a compression fracture tells us a bone has lost height, but it does not yet tell us whether the fracture is new, old, stable, or the true source of pain.
Some compression fractures are very painful. Others are old findings discovered by accident on imaging done for another reason. Your pain location and timing matter.
Common Causes of Compression Fractures
Osteoporosis
Osteoporosis means low bone strength. The bone becomes weaker and more likely to break.
In older adults, osteoporosis is one of the most common causes of vertebral compression fractures. When bone is fragile, a fracture can happen after a minor fall, lifting, bending, coughing, or sometimes no clear injury at all.
A compression fracture may be the first sign that a person has osteoporosis. This is why bone health is a major part of the workup.
Trauma
Trauma can also cause a compression fracture.
A higher-energy fall, car accident, or sports injury can fracture a vertebra even when bone density is normal. In younger patients, trauma is more often part of the story.
After trauma, doctors often look closely at the shape of the fracture, the spinal alignment, and whether the spinal canal is affected.
Cancer, Infection, or Other Less Common Causes
Most compression fractures are related to osteoporosis or trauma. But doctors also consider less common causes when the history or imaging pattern raises concern.
Cancer can weaken bone and cause a fracture. Infection can also damage bone. These causes are less common, but they matter.
Concerning clues may include:
- Known cancer
- Unexplained weight loss
- Fever or chills
- Severe night pain
- Unusual MRI findings
- Fractures at several levels without a clear reason
This does not mean every compression fracture is cancer. It means the full picture matters.
What Compression Fractures Look Like on X-Ray, CT, and MRI
X-Ray
An X-ray is a basic imaging test that uses radiation to show bones.
X-rays can show that a vertebral body has lost height or become wedged. They are often the first test used when a compression fracture is suspected.
But X-rays often cannot prove whether a fracture is new or old. A bone can stay wedged long after it has healed.
CT Scan
A CT scan, or computed tomography scan, uses X-rays and a computer to create detailed bone images.
CT is better than a regular X-ray for seeing bone detail. It can show:
- Fracture lines
- Small bone fragments
- The back wall of the vertebral body
- Retropulsion, which means bone has pushed backward toward the spinal canal
- Narrowing of the spinal canal
CT is often used after trauma or when the fracture shape needs a closer look.
MRI
An MRI, or magnetic resonance imaging scan, uses magnets to show soft tissues, nerves, discs, spinal cord, and bone marrow.
MRI is often the best test for telling whether a compression fracture looks active or old.
What I look for on MRI is marrow edema, because that often helps separate an active fracture from an old compression deformity.
Bone marrow is the inner part of the bone. Edema means swelling-like fluid signal. So marrow edema means there is swelling-like signal inside the bone. This often fits with a newer or still-active fracture.
MRI can also help assess:
- Nerve compression
- Spinal cord compression
- Spinal canal narrowing
- Suspicious marrow replacement, which means normal bone marrow has been replaced by an abnormal-looking signal
- Other possible pain sources, such as disc or joint problems
Acute vs Chronic Compression Fracture
An acute fracture means newer. A subacute fracture means not brand new, but still fairly recent or active. These fractures often show marrow edema on MRI.
A chronic fracture means older. A chronic compression deformity may show old height loss without marrow edema.
An acute or subacute fracture is more likely to match recent pain in the same area. A chronic fracture may be an old finding and may not be the main cause of today’s pain.
MRI is helpful, but it is not magic. Timing of pain, exam findings, medical history, and the exact level of the fracture all matter.
Symptoms: What a Compression Fracture Can Feel Like
A painful compression fracture often causes sudden back pain near the middle of the spine.
The pain may start after:
- A fall
- Lifting
- Bending
- Twisting
- Coughing
- Getting out of bed
- A minor activity that would not usually cause injury
Pain is often worse with:
- Standing
- Walking
- Bending
- Changing position
- Getting in or out of a chair or bed
Pain may improve when lying down.
Thoracic compression fractures can sometimes cause pain that wraps around the ribs or abdomen. Thoracic means the mid-back area where the ribs attach.
Many people do not have leg pain from a simple compression fracture. Leg pain may come from nerve involvement or another condition, such as lumbar spinal stenosis, which means narrowing around nerves in the lower back.
Some chronic compression fractures cause less sharp pain. They may instead lead to height loss, a rounded-forward posture, or a visible change in spinal shape.
A compression fracture on imaging is important, but it does not automatically prove that all current pain is coming from that fracture. The age of the fracture, the exact pain location, and whether there is MRI edema all help determine whether the finding is likely active.
The finding matters most when the patient’s pain location and timing match the level and age of the fracture.
When a Compression Fracture Is More Urgent
Loss of bladder or bowel control, trouble starting urination, and numbness in the saddle area can be signs of a spine emergency. Learn more about cauda equina syndrome warning signs.
How Doctors Decide Whether the Fracture Is Stable
Stability means whether the spine can safely support normal loads without worsening shape, nerve pressure, or alignment problems.
Stability depends on more than the word “fracture.”
Doctors look at:
- How much vertebral height has been lost
- Whether the back wall of the vertebral body is involved
- Whether there is retropulsion into the spinal canal
- Whether the spine is bending forward into kyphosis, which means a rounded-forward curve
- Whether there are nerve or spinal cord symptoms
- How many fractures are present
- Bone quality and osteoporosis risk
- How the injury happened
- Whether there are signs of tumor or infection
Many osteoporotic compression fractures are stable. But this must be assessed in context.
When I review imaging, I am looking beyond the word “fracture”—I want to know whether the back wall of the vertebra, spinal canal, alignment, and nerves are involved.
Treatment Options for Vertebral Compression Fractures
Treatment depends on the person, the fracture, and the symptoms.
The main factors include:
- Pain severity
- Whether the fracture is acute, subacute, or chronic
- Whether MRI shows marrow edema
- Whether the fracture looks stable
- Whether nerves or the spinal cord are compressed
- Bone health
- Trauma history
- Cancer or infection concerns
- Whether pain matches the fracture level
Conservative Treatment
Conservative treatment means treatment without a cement procedure or major surgery.
Many compression fractures improve over weeks to months without kyphoplasty, vertebroplasty, or major spine surgery. Pain can still be significant during the healing phase.
Conservative care may include:
- Activity modification
- Pain control guided by the treating clinician
- Short-term bracing in selected cases
- Physical therapy after the acute pain phase
- Fall prevention
- Osteoporosis evaluation and treatment
- Follow-up imaging when appropriate
Activity modification means avoiding movements that sharply increase pain while still trying to prevent long periods of bed rest when possible.
Physical therapy is often delayed until the worst fracture pain has improved. It may then focus on safe movement, posture, walking, balance, and back muscle strength.
Bracing
A brace is an external support worn around the trunk.
A brace may help comfort and limit painful motion. It does not “glue” the bone together or guarantee faster healing.
Not every patient needs a brace. Bracing decisions depend on:
- Fracture location
- Fracture stability
- Pain level
- Body shape and comfort
- Other medical issues
- Physician preference
Some people feel better with a brace. Others find it uncomfortable or hard to wear. The decision is individualized.
Vertebroplasty and Kyphoplasty
Vertebroplasty and kyphoplasty are minimally invasive cement augmentation procedures. Minimally invasive means they are done through small skin openings rather than a large incision. Cement augmentation means medical cement is placed into the fractured vertebra to help support it.
In vertebroplasty, cement is injected into the fractured vertebra.
In kyphoplasty, a small balloon may be placed into the vertebra first. The balloon can create a cavity and may restore some height in selected cases. Cement is then placed into that space.
These procedures are usually considered when pain is severe and persistent despite conservative treatment, and when imaging suggests an active fracture that matches the pain.
In my practice, kyphoplasty or vertebroplasty is not automatic. The question is whether the patient has persistent fracture-related pain and imaging that supports an active, treatable fracture.
Evidence and recommendations vary. Some studies found little benefit from vertebroplasty compared with a sham procedure in many patients. Other studies found benefit in selected patients with acute, painful fractures. Kyphoplasty may help selected patients with acute painful fractures, but it is not a guaranteed fix.
For a deeper comparison, see vertebroplasty vs kyphoplasty.
Surgery
Major spine surgery is less common for a simple osteoporotic compression fracture.
Surgery may be considered when there is:
- Nerve or spinal cord compression
- An unstable fracture pattern
- Severe deformity
- Worsening kyphosis
- Major trauma
- Tumor-related fracture
- Infection-related bone damage
- Severe canal compromise
This does not mean surgery is routine. It means certain fracture patterns need a more urgent or specialized plan.
Osteoporosis: Why the Bone Health Workup Matters
A compression fracture may be a fragility fracture. A fragility fracture is a break that happens from a low-energy event, such as a fall from standing height or less.
When this happens, bone health needs attention. Treating the current pain is important. Preventing the next fracture is just as important.
A bone health workup may include:
- DXA, which stands for dual-energy X-ray absorptiometry and measures bone density
- A T-score, which compares your bone density to that of a healthy young adult
- Vitamin D level
- Calcium intake review
- Medication review
- Hormone or endocrine evaluation when needed
- Fall-risk assessment
- Osteoporosis medication discussion when appropriate
You can learn more about T-score and bone density testing and how T-scores and bone density testing relate to spine fractures.
Multiple compression fractures can lead to loss of height and a more rounded-forward posture. Posture changes can also come from arthritis, disc wear, muscle weakness, and adult spinal curvature. Read more about adult spinal curvature and posture changes.
How to Read Common MRI Report Phrases
MRI reports can sound alarming. These phrases have specific meanings.
“Chronic Compression Deformity”
A chronic compression deformity usually means older height loss or an old fracture shape.
If there is no marrow edema, it may not be the cause of new pain. But old fractures can still affect posture or cause mechanical strain in some people.
“Acute or Subacute Compression Fracture”
Acute or subacute compression fracture suggests a newer or still-active fracture.
This phrase is often linked with marrow edema on MRI. It is more likely to matter if your pain started recently and is located near that same spinal level.
“Vertebral Body Height Loss”
Vertebral body height loss describes how much the bone has collapsed.
Mild height loss is different from severe collapse. The amount of height loss is only one part of the decision. Doctors also look at alignment, canal space, nerves, and symptoms.
“Retropulsion”
Retropulsion means a portion of bone has pushed backward toward the spinal canal.
The spinal canal is the tunnel that holds the spinal cord and nerves. Retropulsion matters more when it narrows the canal or presses on nerve tissue.
Retropulsion does not automatically mean paralysis. But it does need careful interpretation.
“Marrow Edema”
Marrow edema means swelling-like signal inside the bone on MRI.
It often suggests a recent or active fracture. It does not prove the exact date of injury. It also does not prove that the fracture is the only source of pain.

Frequently Asked Questions
Is a spinal compression fracture serious?
It can be, but many are not emergencies.
A compression fracture means a spinal bone has lost height. Some are stable and treated without major surgery. Others need urgent evaluation, especially if there is weakness, numbness, walking trouble, bladder or bowel changes, fever, cancer history, major trauma, or severe uncontrolled pain.
Can a vertebral compression fracture heal on its own?
Many vertebral compression fractures improve over weeks to months without a cement procedure or major surgery.
Healing depends on the fracture pattern, bone strength, pain level, and whether there are nerve or stability concerns. Some people need bracing, follow-up imaging, osteoporosis treatment, or a procedure.
How can doctors tell if a compression fracture is new or old?
MRI is often the most helpful test.
A newer or active fracture often shows marrow edema, which is swelling-like signal inside the bone. An older fracture may show height loss without edema.
Doctors also compare the scan with when your pain started and where it is located.
What does marrow edema mean on a spine MRI?
Marrow edema means swelling-like signal inside the bone.
In a compression fracture, it often suggests the fracture is recent or still active. It does not prove the exact date of injury. It also does not prove that all pain is coming from that fracture.
Do I need kyphoplasty or vertebroplasty?
Not automatically.
Kyphoplasty and vertebroplasty are usually considered for selected people with severe, persistent pain that matches an active fracture on imaging. Many compression fractures are first treated without these procedures.
The decision depends on pain severity, fracture age, MRI findings, stability, medical history, and overall health.
What is the difference between vertebroplasty and kyphoplasty?
Both procedures place medical cement into a fractured vertebra.
In vertebroplasty, cement is injected directly into the fractured bone.
In kyphoplasty, a small balloon is usually inflated first to create a space. This may restore some height in selected cases before cement is placed.
Can a compression fracture cause nerve damage?
Most simple osteoporotic compression fractures do not cause nerve damage.
Nerve or spinal cord problems can happen if bone pushes backward into the spinal canal, if the fracture is unstable, or if there is trauma, tumor, infection, or another spine condition.
New weakness, numbness, walking trouble, or bladder and bowel changes need urgent evaluation.
Is a compression fracture the same as osteoporosis?
No.
A compression fracture is a broken or collapsed spinal bone. Osteoporosis is weakened bone density.
Osteoporosis is a common cause of compression fractures, especially in older adults. But trauma, cancer, infection, and other causes can also lead to compression fractures.
Can an old compression fracture still cause pain?
Sometimes, yes.
An old compression deformity without marrow edema may be an incidental finding. It may not explain new pain. But old fractures can affect posture, spinal mechanics, or nearby joints and muscles.
The best interpretation comes from matching the imaging with pain location, timing, exam findings, and medical history.
When should I seek urgent care for a compression fracture?
Seek urgent care if back pain comes with new weakness, numbness, trouble walking, bladder or bowel changes, groin or saddle numbness, fever, known cancer, unexplained weight loss, major trauma, severe uncontrolled pain, or rapidly worsening posture.
SpineClarity is not an emergency service.
