经皮椎体成形术术后骨水泥分布的疗效分析及对再骨折的影响

Objective To explore the efficacy of bone cement distribution in percutaneous vertebroplasty(PVP) on osteoporotic vertebral compression fractures(OVCF) and its influence on postoperative refracture. Methods This study was a retrospective analysis. The included subjects were the data of 60 patients diagnosed and treated with OVCF in the Department of Orthopedics of Dongguan Nancheng Hospital from March 2023 to November 2024. According to the cross-sectional bone cement distribution area of the CT images of the affected vertebrae, the included patients were divided into 3 groups. They were respectively the TL1 group(n=15), the TL2 group(n=24), and the TL3 group(n=21). After admission, all groups underwent elective PVP treatment. The pain degree [Visual Analogue Scale(VAS)] and vertebral function [Oswestry Disability Index(ODI)] of the three groups before the operation and at 2 days, 1 month, 6 months, and 12 months after the operation were compared. The incidence of bone cement leakage and refracture in the three groups was statistically analyzed. Results The VAS scores of the three groups at 2 days, 1 month, 6 months and 12 months after the operation were all lower than those before the operation, and the VAS scores of the TL3 group at each of the above time points were lower than those of the TL1 group and the TL2 group(P<0.05). The ODI scores of the three groups at 2 days, 1 month, 6 months and 12 months after the operation were all lower than those before the operation, and the ODI scores of the TL3 group at each time point were lower than those of the TL1 group and the TL2 group(P<0.05). Conclusion PVP can effectively relieve the pain of patients with OVCF and improve their function. Its therapeutic effect is positively correlated with the distribution range of bone cement in the vertebral body. The more fully the bone cement diffuses, the more significant the effect will be.
