Background: Vertebral compression fractures can cause severe mechanical pain in spite of conservative treatments. Although vertebroplasty is an effective treatment for vertebral compression fractures, it is not strongly indicated in some patients. This study was performed to verify the usefulness of ramus communicans nerve block in patients suffering from back pain due to a vertebral compression fracture. Methods: A randomized clinical trial was carried out in 34 patients with a vertebral compression fracture after conservative therapy had failed. Nerve blocks on the ramus communicans corresponding to vertebral compression fracture were performed once a week for 2 consecutive weeks under C-arm fluoroscopic guidance. The pain scores were evaluated before and after each nerve block using a 100 mm VAS (visual analog scale), and the side effects were also checked. Results: All patients tolerated the procedures well. The VAS pain scores were significantly lower than that at the baseline (P
