Effectiveness of Thoracic Paravertebral Block in Minimally Invasive Vertebroplasty: A Retrospective Cohort Study Focusing on Pain Trajectories and Sagittal Spinal Alignment

Ultrasound-guided TPVB combined with GA significantly improves postoperative pain trajectories, reduces opioid consumption, and enhances sagittal spinal alignment in MIVP patients. TPVB may modulate nociceptive and neuroinflammatory pathways, offering a safer analgesic option for spinal surgery in osteoporotic patients. Prospective randomized trials are warranted to confirm these findings.
