Clinical Scorecard: Identifying Risk Factors for Adjacent Vertebral Fractures Following Percutaneous Vertebroplasty in Osteoporotic Compression Fracture Patients

At a Glance

Key Highlights

• Advanced age (OR = 1.045 per year) and low lumbar spine BMD (OR = 2.85 per SD decrease) are independent risk factors for AVF after PVP.
• Individual predictors (age or BMD alone) have limited predictive accuracy (AUC < 0.7), but a combined model improves prediction (AUC = 0.706).
• Systemic osteoporosis management should be prioritized over surgical technical details to prevent AVF.

Guideline-Based Recommendations

Diagnosis

• Assess lumbar spine BMD preoperatively using dual-energy X-ray absorptiometry (DXA).
• Evaluate patient age and BMI as part of risk stratification.
• Exclude patients with nerve root compression, pathological fractures, or severe comorbidities contraindicating surgery.

Management

• Perform initial single-level percutaneous vertebroplasty for osteoporotic vertebral compression fractures.
• Prioritize systemic osteoporosis treatment to reduce risk of adjacent vertebral fractures post-PVP.
• Monitor and manage bone cement leakage as a potential contributing factor.

Monitoring & Follow-up

• Follow patients for at least 12 months post-PVP to detect occurrence of AVF, especially within first 6 months.
• Use clinical and imaging follow-up to identify new vertebral fractures.
• Monitor bone mineral density changes and adjust osteoporosis management accordingly.

Risks

• Advanced age and low BMD significantly increase risk of adjacent vertebral fractures after PVP.
• Lower BMI is associated with higher AVF risk.
• Bone cement leakage may contribute to AVF but requires further validation.

Patient & Prescribing Data

429 patients with osteoporotic vertebral compression fractures undergoing initial single-level PVP

Combined risk assessment using age and lumbar spine BMD improves prediction of AVF risk, supporting targeted osteoporosis management alongside surgical intervention.

Clinical Best Practices

• Conduct comprehensive preoperative evaluation including lumbar spine BMD measurement and assessment of systemic health.
• Use combined predictive models incorporating age and BMD for preliminary risk stratification of AVF.
• Implement systemic osteoporosis therapies post-PVP to mitigate risk of adjacent vertebral fractures.
• Ensure at least 12 months of clinical and imaging follow-up to monitor for AVF occurrence.
