Osteoporosis-related compression fractures are treated in layers: first controlling pain and keeping you moving, then, for selected patients whose pain does not settle, stabilizing the broken vertebra with a cement procedure such as vertebroplasty or kyphoplasty, and always treating the underlying osteoporosis so the next fracture does not happen. The most important innovation of recent years is not a single procedure but the recognition that one spinal fracture is a warning sign that demands bone-strengthening treatment.
This article walks through each approach, who it suits, and what recovery usually looks like.
What Is an Osteoporotic Compression Fracture?
A vertebral compression fracture happens when the front part of a spinal bone (vertebra) collapses, giving it a wedge shape. In healthy bone this takes a major injury, but in osteoporosis, where bone mass and internal architecture are weakened, it can follow a minor fall, lifting a shopping bag, a cough or even no obvious event at all.
These fractures most often occur in the mid-back and the junction between the mid and lower back. Many are painless and only discovered on an X-ray, while others cause sudden, sharp back pain. Over time, several fractures can lead to height loss and a forward-curved posture called kyphosis, which may crowd the chest and abdomen and affect breathing and appetite.
Risk rises with age, menopause, low body weight, smoking, heavy alcohol use, long-term corticosteroid treatment, low calcium and vitamin D, and a previous fracture. For the full picture of the condition, see our osteoporosis guide.
How Compression Fractures Are Diagnosed
Diagnosis starts with the history and examination, followed by imaging. A plain X-ray usually shows the collapsed vertebra. MRI is valuable when a procedure is being considered because it shows bone marrow edema, a sign that a fracture is recent and still healing, which helps separate a fresh fracture from an old one. CT gives fine bony detail when the back wall of the vertebra may be involved.
Fractures are often graded by how much height the vertebra has lost:
| Grade | Approximate height loss | Description |
|---|---|---|
| Grade 1 (mild) | About 20 to 25% | Slight wedging; may be missed without careful review |
| Grade 2 (moderate) | About 25 to 40% | Clear deformity; often linked with pain and posture change |
| Grade 3 (severe) | More than 40% | Marked collapse; higher risk of kyphosis and further fractures |
A DEXA scan (dual-energy X-ray absorptiometry) then measures bone mineral density. A T-score of -2.5 or lower confirms osteoporosis, but a low-trauma spinal fracture on its own is enough to diagnose clinical osteoporosis, whatever the T-score.
As a hematologist, I add one important point: not every collapsed vertebra is osteoporosis. Multiple myeloma, a cancer of plasma cells in the bone marrow, and cancer that has spread to bone can both cause vertebral collapse. Unexplained fractures, especially with anemia, kidney problems or a raised calcium, deserve blood tests such as a full blood count and serum protein studies before the fracture is labeled osteoporotic.
Conservative Treatment: The First Step for Most Patients
Most compression fractures heal on their own over roughly 6 to 12 weeks. Conservative care aims to control pain enough that you stay active, because prolonged bed rest weakens muscle and bone further.
- Pain relief: paracetamol (acetaminophen) and, when appropriate, anti-inflammatory drugs or short courses of stronger analgesics. Older adults need careful dosing to avoid drowsiness and falls.
- Calcitonin: sometimes used for a short period in the acute phase because it may ease fracture pain, though it is not a long-term bone treatment.
- Bracing: a spinal orthosis can provide comfort for some patients, but it should not replace gentle movement.
- Physiotherapy: posture training, back-extensor strengthening and balance work help reduce pain and lower the risk of future falls.
Vertebroplasty and Kyphoplasty
For patients whose severe pain persists despite good conservative care, or who cannot mobilize because of pain, percutaneous vertebral augmentation may be considered. Both procedures are done through the skin using needles guided by live X-ray, usually as a day case or short stay.
| Feature | Vertebroplasty | Kyphoplasty |
|---|---|---|
| Technique | Bone cement injected directly into the fractured vertebra | A balloon is inflated first to create a cavity, then filled with cement |
| Height restoration | Minimal | May restore some height in recent fractures |
| Main aim | Stabilize the fracture and reduce pain | Stabilize, reduce pain and partly correct wedging |
| Key risks | Cement leakage; rarely nerve or lung complications | Similar risks; cement leakage may be less frequent |
The evidence for these procedures is genuinely debated. Sham-controlled trials have produced mixed results, so guidelines generally reserve them for carefully selected patients, typically those with a recent fracture confirmed on MRI and pain that has not responded to other measures. They are not a routine first choice. A concern also exists that treated segments may alter the load on neighboring vertebrae, so treating the underlying bone disease remains essential.
Newer refinements include implants that support the vertebra from inside, improved cement formulations, and image-navigation systems to make needle placement more precise. These are best viewed as refinements of the same concept rather than replacements for good medical care.
Treating the Osteoporosis to Prevent the Next Fracture
After one vertebral fracture, the chance of another rises sharply, particularly in the following year. This is why many hospitals now run fracture liaison services, which make sure anyone with a fragility fracture is assessed and started on treatment.
- Bisphosphonates (such as alendronate, risedronate or zoledronic acid) slow bone breakdown and are the usual first-line option.
- Denosumab is an injection every six months; it must not be stopped abruptly without a follow-on plan, because bone loss and fractures can rebound.
- Anabolic (bone-building) drugs such as teriparatide, abaloparatide and romosozumab are often preferred for people with very high fracture risk, including those with multiple vertebral fractures.
- Foundations: adequate calcium and vitamin D, protein, weight-bearing exercise, stopping smoking and fall prevention at home.
Specialists such as rheumatologists and endocrinologists often lead this long-term care. Our article on the role of rheumatologists in treating osteoporosis explains how they choose and sequence these medicines.
When to See a Doctor
See a doctor if you have new back pain after a minor fall or strain, especially if you are over 50 or have known osteoporosis. Seek urgent care if back pain comes with any of the following:
- Numbness, weakness or tingling in the legs
- Loss of bladder or bowel control
- Fever, night sweats or unexplained weight loss
- A history of cancer, or pain that is worse at night and at rest
Frequently Asked Questions
How long does an osteoporotic compression fracture take to heal?
Most heal within about 6 to 12 weeks, with pain easing gradually over that time. Some people have lingering discomfort from changed posture, which physiotherapy can help.
Is kyphoplasty better than vertebroplasty?
Neither has been clearly proven superior for pain relief. Kyphoplasty may restore a little height in recent fractures, while vertebroplasty is simpler; the choice depends on the fracture and the specialist’s experience.
Can I prevent another compression fracture?
Yes, the risk can be reduced substantially. Effective osteoporosis medication, adequate calcium and vitamin D, exercise and fall prevention together lower the chance of further fractures.
Should I stay in bed after a spinal fracture?
No. Short rest during the most painful days is reasonable, but early, gentle walking protects muscle and bone and reduces the risk of blood clots and pneumonia.
Key Takeaways
- Most osteoporotic compression fractures heal with pain control, activity and physiotherapy.
- Vertebroplasty and kyphoplasty are options for selected patients with persistent severe pain, not routine first-line care.
- Always rule out other causes, such as myeloma, when a fracture is unexplained.
- Treating the osteoporosis itself is the step that prevents the next fracture.
