Complications of Vertebroplasty in Adults: Incidence, Etiology, and Therapeutic Strategies—A Comprehensive, Systematic Literature Review

Percutaneous vertebroplasty (PVP) has emerged as a key intervention for painful vertebral compression fractures in osteoporotic and metastatic disease, but its safety profile warrants comprehensive evaluation. We conducted a PRISMA-compliant systematic review of studies published between 2009 and 2024, identifying 15 clinical studies (n ≈ 8500 patients) that reported PVP-related complications in adults with osteoporotic or neoplastic fractures. Data extraction focused on complication incidence, presentation, imaging findings, risk factors, and management strategies. Cement leakage was the most frequently detected event (20–70% of levels, higher in neo-plastic lesions), yet symptomatic neural or vascular sequelae occurred in <1%. Pulmonary cement embolism appeared on imaging in 2–26% of cases but was clinically evident in ≤0.5%, with conservative management or brief anticoagulation sufficing for most patients. New vertebral fractures developed in 8–20% of osteoporotic and up to 30% of metastatic cohorts, paralleling underlying bone fragility rather than PVP itself. Postprocedural infection (0.2–0.5%) and neurologic injury (<0.5%) were uncommon but required prompt surgical and antibiotic interventions. Overall, PVP’s benefits—rapid pain relief and mechanical stabilization—outweigh its risks when performed with meticulous technique, vigilant imaging, and multidisciplinary follow-up, confirming its favorable safety profile in both osteoporosis and spinal malignancy.
