OSTEOPOROSIS AND SPINE FRACTURE

Osteoporosis, Spine Fractures, and Vertebroplasty: Diagnosis and Treatment

Osteoporosis is a progressive bone disease that weakens bone strength and density, making bones fragile and prone to fractures. Among all osteoporotic fractures, spinal compression fractures are the most common and often cause severe pain, disability, and reduced quality of life. Early diagnosis of osteoporosis, proper classification of spine fractures, and modern treatments like vertebroplasty play a key role in managing this condition.

What is Osteoporosis?

Osteoporosis literally means “porous bone.” It occurs when bone resorption outpaces bone formation, leading to loss of bone mass and deterioration of bone microarchitecture.

  • Risk factors: Aging, post-menopausal status, sedentary lifestyle, smoking, low calcium/vitamin D intake, chronic steroid use, genetic predisposition.
  • Common fracture sites: Spine (vertebrae), hip, wrist, ribs.
  • Symptoms: Often called a “silent disease” since patients may not notice symptoms until a fracture occurs. Chronic back pain and loss of height may indicate vertebral fractures.

Diagnosis of Osteoporosis

Accurate and early diagnosis is essential to prevent fractures.

1. Bone Mineral Density (BMD) Test

  • Dual-energy X-ray Absorptiometry (DEXA scan): Gold standard for osteoporosis diagnosis.
  • T-score classification:
    • Normal: ≥ -1
    • Osteopenia: -1 to -2.5
    • Osteoporosis: ≤ -2.5

2. Laboratory Tests

  • Calcium, vitamin D, phosphorus, parathyroid hormone (PTH).
  • Rule out secondary causes (thyroid disease, renal disease, steroid use).

3. Imaging for Spine Fractures

  • X-ray: Identifies vertebral compression fractures.
  • MRI: Differentiates between acute and old fractures.
  • CT scan: Provides detailed bony architecture before interventions.

Spine Fractures in Osteoporosis

Osteoporotic vertebral compression fractures are the most frequent and often occur with minimal trauma.

Symptoms of Spinal Fractures

  • Sudden, severe back pain
  • Loss of height and spinal deformity (kyphosis or “dowager’s hump”)
  • Restricted mobility and reduced quality of life

Classification of Spine Fractures

Spinal fractures can be classified based on morphology and severity.

1. Morphological Classification

  • Wedge fracture: Anterior vertebral body collapses.
  • Biconcave fracture: Central portion of vertebra collapses.
  • Crush fracture: Entire vertebral body loses height.

2. AO Spine Classification

  • Type A: Compression injuries
  • Type B: Tension band injuries
  • Type C: Rotational or translational injuries

Treatment of Osteoporosis and Spine Fractures

1. Medical Management

  • Calcium & Vitamin D supplementation
  • Bisphosphonates (alendronate, zoledronic acid)
  • Denosumab – monoclonal antibody to reduce bone resorption
  • Teriparatide – anabolic therapy that stimulates bone formation
  • Lifestyle modifications – weight-bearing exercises, fall prevention strategies

2. Conservative Management of Spine Fractures

  • Bed rest (short-term)
  • Analgesics for pain relief
  • Bracing to support the spine
  • Physiotherapy and rehabilitation

3. Interventional Treatment: Vertebroplasty

Vertebroplasty is a minimally invasive procedure where bone cement (polymethylmethacrylate, PMMA) is injected into a fractured vertebra to stabilize it and relieve pain.

Vertebroplasty

Indications

  • Painful osteoporotic vertebral compression fractures not responding to conservative therapy
  • Malignant vertebral fractures (metastases, myeloma)
  • Selected traumatic vertebral fractures

Contraindications

  • Asymptomatic fractures
  • Spinal canal compromise with neurological deficit
  • Active infection

Procedure Steps

  1. Patient positioned prone on the operating table.
  2. Local anesthesia or sedation is given.
  3. Under fluoroscopic or CT guidance, a needle is inserted into the fractured vertebral body.
  4. Low-viscosity bone cement (PMMA) is injected.
  5. Cement hardens within minutes, stabilizing the fracture.

Benefits

  • Immediate and significant pain relief in most patients
  • Improved mobility and quality of life
  • Prevention of further vertebral collapse

Risks and Complications

  • Cement leakage (most common)
  • Pulmonary embolism (rare)
  • Infection
  • Adjacent vertebral fractures due to altered biomechanics

Key Takeaways

  • Osteoporosis is a silent disease but can lead to painful and disabling spinal fractures.
  • Diagnosis relies on DEXA scans, labs, and imaging.
  • Classification of spine fractures guides treatment strategy.
  • Vertebroplasty is a safe, effective, and minimally invasive option for patients with painful vertebral compression fractures.

Call to Action

If you or a loved one suffers from osteoporosis, spinal fractures, or chronic back pain, consult a pain specialist or spine interventionist for proper evaluation.
Modern interventional procedures like vertebroplasty can help restore mobility, reduce pain, and improve quality of life.
