Objective: We aimed to investigate the effectiveness of the amount of polymethylmethacrylate used in pain control and maintenance of long-term vertebra corpus height in patients undergoing percutaneous vertebroplasty due to osteoporotic compression fracture of the lumbar vertebra.Method: A total of 60 patients who underwent unilateral percutaneous vertebroplasty between 2014 and 2019 due to osteoporotic compression fracture of the lumbar vertebrae were included in the study. Patients who received 5 ml and 3 ml cement injection were retrospectively analyzed. Of patients, postoperative visual analogue scale (VAS) score and anterior vertebral height of the patients at 1st-year control were evaluated.Results: In the postoperative period, the mean visual analogue scale score was 2.3 +/- 0.46 in the 5 ml injected group and 2.2 +/- 0.4 in the 3 ml injected group (p5 ml=0.001, p3 ml=0.001). There was a statistically significant decline in pain control in both groups. The mean anterior vertebral height loss (AVHL) in the 5 ml injected group was 31.5 +/- 0.40%, and 32.6 +/- 0.47% in the 3 ml injected group (p5 ml=0.820, p3ml=0.870). There was no statistically significant alteration in both groups.Conclusion: Our results indicate that the 3 ml polymethylmethacrylate injection during the percutaneous vertebroplasty procedure provides adequate pain control and stabilization in patients with lumbar vertebral osteoporotic fracture. Therefore we think that small amount of polymethylmethacrylate (3 ml) is sufficient to avoid undesirable complications in this patient group.
