Vertebral compression fracture - Causes, Treatment & When to See a Doctor

What is Vertebral compression fracture?

A vertebral compression fracture (VCF) is a break or collapse of one or more of the vertebrae—the small bones that make up the spine. The fracture typically involves the anterior (front) portion of the vertebral body, causing it to become shortened and wedge‑shaped. When this occurs, the height of the affected spinal segment is reduced, which can lead to pain, posture changes (often a forward‑bending “kyphosis”), and, in severe cases, neurologic problems if the spinal canal is compromised.

VCFs are most common in the thoracic (mid‑back) and lumbar (lower back) regions, where the spine bears the greatest load. Although they can happen after a traumatic event such as a fall, many VCFs develop gradually due to weakened bone structure.

Key points

• Most frequent in people over 60, especially women with osteoporosis.
• Can cause sudden or progressive back pain, often worsening with standing or bending.
• Early identification is important to prevent further collapse and to preserve mobility.

Common Causes

While osteoporosis is the leading underlying factor, several conditions and situations can predispose someone to a vertebral compression fracture.

• Osteoporosis – age‑related loss of bone density, the most common cause.
• Osteopenia – milder bone loss that still weakens vertebrae.
• Traumatic injury – falls from standing height, motor‑vehicle accidents, or sports injuries.
• Spinal metastases – cancer that spreads to the vertebrae (breast, prostate, lung, kidney) can erode bone.
• Multiple myeloma – a cancer of plasma cells that frequently involves the spine.
• Paget’s disease of bone – abnormal bone remodeling creates structurally weak vertebrae.
• Long‑term corticosteroid therapy – steroids such as prednisone decrease bone formation.
• Hyperparathyroidism – excess parathyroid hormone accelerates bone loss.
• Rheumatoid arthritis – inflammatory disease can lead to secondary osteoporosis.
• Severe vitamin D deficiency – impairs calcium absorption and bone mineralization.

Associated Symptoms

Symptoms vary with the fracture’s location, severity, and whether other spinal structures are involved.

• Localized back pain – sharp, stabbing, or aching pain that worsens with upright posture, walking, or lifting.
• Height loss – noticeable reduction in stature (often a few centimeters).
• Kyphosis – a forward‑bending posture sometimes called a “dowager’s hump.”
• Limited range of motion – difficulty bending, twisting, or turning.
• Radiating pain – pain may travel to the ribs, abdomen, or hips.
• Numbness, tingling, or weakness – if the fracture compresses nerve roots or the spinal cord.
• Difficulty breathing – severe kyphosis can impair lung capacity.
• Nighttime pain – may be more pronounced when lying down.

When to See a Doctor

Prompt medical evaluation is essential to differentiate a VCF from other causes of back pain and to prevent complications.

• Sudden, intense back pain after a fall or lift.
• Progressive pain that does not improve with rest or over‑the‑counter pain relievers.
• New or worsening numbness, tingling, or weakness in the legs or arms.
• Loss of bladder or bowel control (possible sign of spinal cord compression).
• Unexplained height loss or a visible change in spinal curvature.
• Persistent fever or chills with back pain (may suggest infection).

If any of these occur, schedule an appointment promptly; for neurologic signs or loss of bladder/bowel control, seek emergency care.

Diagnosis

Healthcare professionals use a combination of clinical assessment and imaging studies to confirm a vertebral compression fracture.

Physical examination

• Inspection for kyphosis or abnormal posture.
• Palpation to locate tenderness over the spine.
• Neurologic testing (strength, sensation, reflexes) to assess spinal cord involvement.

Imaging studies

• X‑ray – first‑line, quick view of vertebral height loss and fracture lines.
• Magnetic resonance imaging (MRI) – identifies bone edema (acute fracture), spinal canal compromise, and soft‑tissue injury.
• Computed tomography (CT) – provides detailed bone anatomy, useful for surgical planning.
• Dual‑energy X‑ray absorptiometry (DEXA) scan – assesses overall bone mineral density to evaluate osteoporosis risk.

Laboratory tests (when indicated)

• Calcium, phosphate, vitamin D levels – assess metabolic bone disease.
• Serum protein electrophoresis – screens for multiple myeloma.
• Parathyroid hormone (PTH) – evaluates hyperparathyroidism.

Treatment Options

Management is individualized based on fracture severity, pain level, underlying cause, and patient health status.

Conservative (non‑surgical) care

• Pain control – acetaminophen, NSAIDs (if no contraindication), or short‑term opioids for severe pain.
• Bracing – rigid thoracolumbar braces limit motion, reduce pain, and allow healing (typically 6–12 weeks).
• Physical therapy – core‑strengthening, posture training, and gentle stretching improve stability and prevent future falls.
• Activity modification – avoid heavy lifting, high‑impact sports, and prolonged standing until pain subsides.
• Osteoporosis treatment – bisphosphonates (e.g., alendronate), denosumab, teriparatide, or selective estrogen receptor modulators to improve bone density and reduce repeat fractures.
• Nutritional support – calcium (1,200 mg/day) and vitamin D (800‑1,000 IU/day) supplementation.

Minimally invasive procedures

• Vertebroplasty – percutaneous injection of bone cement (PMMA) into the fractured vertebra to stabilize it and reduce pain.
• Kyphoplasty – similar to vertebroplasty but uses a balloon to restore vertebral height before cement placement.
• Both procedures are performed under local anesthesia with fluoroscopic guidance and are most effective when performed within 6 weeks of the fracture.

Surgical options (rare)

• Posterior spinal fusion or instrumentation for highly unstable fractures, neurologic compromise, or when minimally invasive techniques are not feasible.
• Decompression surgery if there is significant spinal cord or nerve root compression.

Decision‑making should involve shared discussion with the patient, weighing pain relief, functional recovery, and procedural risks.

Prevention Tips

Because many VCFs stem from weakened bone, prevention focuses on bone health and fall avoidance.

• Bone‑strengthening lifestyle – weight‑bearing exercises (walking, dancing), resistance training, and balance activities such as tai chi.
• Adequate nutrition – 1,200 mg calcium and 800‑1,000 IU vitamin D daily, plus a diet rich in fruits, vegetables, and protein.
• Bone density screening – DEXA scan at age 65 for women and 70 for men, or earlier if risk factors exist.
• Medication review – discuss long‑term steroid use or other drugs (e.g., proton‑pump inhibitors) that may affect bone health with your provider.
• Fall‑proof your home – remove loose rugs, install grab bars, ensure adequate lighting, and use non‑slip mats in the bathroom.
• Quit smoking and limit alcohol – both habits accelerate bone loss.
• Regular health check‑ups – monitor chronic conditions such as rheumatoid arthritis or diabetes that can influence bone quality.
