Abstract
PURPOSE: This study aimed to investigate the effect of precooling storage of bone cement in percutaneous vertebroplasty(PVP) for the patients with osteoporotic vertebral compression fracture (OVCF). METHODS: A total of 207 OVCF patients who underwent PVP were included in this study. Two different storage methods for the bone cement were randomly utilized: an operating room (NT group, 23 °C) and a refrigerator (PC group, 4 °C). Clinical outcomes were evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI) scores. In addition, radiographic evaluations were performed using anterior vertebral height and Cobb angle. RESULTS: The time of cement infusion was 10.8 ± 2.1 min in the PC group, which was significantly longer compared to the NT group (6.9 ± 1.8 min)(P < 0.0001). However, the postoperative VAS score was lower in the PC group than the NT group (P < 0.0001). Moreover, compared to the NT group, the cement distribution score and rate of cement touching both upper and lower vertebral endplates were higher in the PC group (P < 0.0001 and = 0.037, respectively). Additionally, the anterior vertebral height was higher in the PC group compared to the NT group at both the 2-day postoperative assessment and the final follow-up (P = 0.046 and 0.026, respectively). Lastly, the rates of cement leakage and re-compression were lower in the PC group (P = 0.016 and 0.034, respectively) compared with the NT group. CONCLUSION: Precooling storage of bone cement may prolong manipulation time in percutaneous vertebroplasty, optimize pain relief for patients, and mitigate the risk of bone cement leakage and re-compression.
