目的 分析两种椎体成形术在老年骨质疏松性脊柱压缩骨折（OVCF）中的应用效果。方法 选择2020年1月—2022年10月收治的210例OVCF患者作为研究对象,根据手术方式的不同分为经皮椎体成形术（PVP）组和椎体后凸成形术（PKP）组,每组各105例,记录两组治疗效果。结果 PKP组手术时长短于PVP组,术中出血量少于PVP组,骨水泥量显著少于PVP组（P<0.05）。PKP组治疗优良率显著高于PVP组（P<0.05）。术前,两组脊柱功能、Cobb角、疼痛程度和日常生活能力进行比较,差异无统计学意义（P>0.05）;术后1个月,两组脊柱功能、Cobb角、疼痛程度和日常生活能力改善显著且PKP组显著优于PVP组（P<0.05）。PKP组并发症发生率显著低于PVP组（P<0.05）。结论 与PVP进行比较,PKP可显著缩短手术时长、减少术中出血量、减少骨水泥灌注量,改善脊柱功能,改善Cobb角,提高日常生活能力,提升治疗优良率。

Objective To analyze the effects of two vertebroplasty procedures in the elderly with osteoporotic vertebral compression fracture （OVCF）. Methods A total of 210 patients with OVCF admitted to our hospital from January 2020 to October 2022 were selected as study subjects. According to different surgical methods, they were divided into a percutaneous vertebroplasty （PVP） group and a percutaneous kyphoplasty （PKP） group, with 105 cases in each group, and the therapeutic effects of the two groups were recorded. Results Operation duration, intraoperative blood loss, and bone cement volume in the PKP group were significantly lower than those in the PVP group （P<0.05）. The excellent and good rate of treatment of the PKP group was significantly higher than that of the PVP group （P<0.05）. Before surgery, there were no significant differences in spinal function, Cobb angle, pain degree, and daily living activities between the two groups （P>0.05）. One month after surgery, spinal function, Cobb angle, pain degree, and daily living activities were significantly improved in both groups, and the PKP group was significantly better than the PVP group （P<0.05）. The complication rate of the PKP group was significantly lower than that of the PVP group （P<0.05）. Conclusion Compared with PVP, PKP can significantly shorten the duration of surgery, reduce intraoperative blood loss and the amount of bone cement perfusion, improve spinal function, Cobb angle, and daily living activities, and increase the rate of excellent and good treatment.
