ABSTRACT
BACKGROUND: Percutaneous vertebroplasty has been extensively applied In the treatment of senile osteoporotic vertebral compression fracture with pain. However, the appropriate dose of bone cement remains controversial. OBJECTIVE: To compare the efficacy and complications of different viscosities of high-dose bone cement applied In the treatment of osteoporotic vertebral compression fractures by percutaneous vertebroplasty. METHODS: One hundred and sixty-nine patients with single-segment osteoporotic fractures at thoracolumbar level (T12-L2) admitted at Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from February 2014 to December 2018 were Included. All patients were treated by percutaneous vertebroplasty with high-dose (> 4 mL) bone cement at low viscosity (n=85, control group) and high viscosity (n=84, observation group). The Visual Analogue Scale score, anterior vertebral height, Cobb angle and bone cement leakage were recorded before and 2 days after surgery. The study was approved by the Medical Ethics Committee of Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine, China (approval No. SH9H-2019-T90-1). RESULTS AND CONCLUSION: (1) The Visual Analogue Scale score at postoperative 2 days in both groups were significantly lower than that at baseline (P 0.05). (2) The anterior vertebral height at postoperative 2 days in both groups was significantly higher than that at baseline (P 0.05). (3) Compared with the baseline level, the Cobb angle at postoperative 2 days in both groups was significantly decreased (P 0.05). (4) The incidence of bone cement leakage in the observation group (36/84,42.9%) was significantly lower than that in the control group (57/85, 67.1 %) (P < 0.05). The incidence of leakage In paravertebral vessels and spinal canal in the observation group was significantly lower than that in the control group (P < 0.05). (5) Peri-Implant Infection, allergic reaction, Immune and rejection reactions occurred in neither groups. (6) These results Indicate that treatment of senile osteoporotic vertebral compression fractures with high dose of low- and high-viscosity bone cement can result In good clinical outcomes. However, the Incidence of leakage is higher in the low-viscosity bone cement, and high-viscosity bone cement can significantly reduce the risk of leakage, especially the leakage of paravertebral blood vessels and spinal canal.
