Abstract
Background: Osteoporotic vertebral compression fractures (OVCFs) are common in the elderly, severely impacting health and quality of life. Percutaneous vertebroplasty (PVP) is a primary treatment, with bone cement distribution being a key factor influencing its efficacy.
Objective: This study aimed to evaluate the impact of bone cement distribution patterns on clinical outcomes in unilateral PVP for OVCFs.
Methods: A total of 145 patients undergoing first-time unilateral PVP were retrospectively analyzed. Based on postoperative anteroposterior X-rays, patients were divided into three groups according to cement coverage: Group A (uniform distribution across three vertebral regions, n=57), Group B (covering >1/2 to ≤2/3, n=51), and Group C (covering >1/3 to ≤1/2, n=37). Primary outcomes (VAS, ODI, vertebral height recovery, refracture rate) and secondary outcomes were compared.
Results: At one-year follow-up, VAS scores were significantly lower in Groups A (2.12±0.54) and B (2.16±0.54) than in Group C (2.43±0.50, P<0.05). Vertebral height recovery was superior in Groups A and B compared to Group C (P<0.05). The overall refracture rate was significantly lower in Group A (3.6%) than in Group C (18.9%, P<0.05), with no significant difference from Group B (3.9%). Group A received a higher cement volume (4.95±0.43 mL) than Groups B and C (P<0.05).
Conclusion: Bone cement distribution crossing the vertebral midline is associated with better pain relief, improved vertebral height restoration, and a lower refracture rate after unilateral PVP. However, exceeding two-thirds vertebral coverage does not appear to be a critical factor for surgical efficacy.
