摘　　要：目的:探究骨水泥弥散分布等级与骨质疏松性脊柱骨折(OVCF)患者骨折复位、术后椎体高度丢失的关系。方法:选取OVCF患者50例为研究对象,根据患者骨水泥弥散分布情况分为Ⅰ级(n=16)、Ⅱ级(n=20)、Ⅲ级(n=14);患者均接受经皮椎体成形术或经皮椎体后凸成形术。比较骨水泥弥散分布不同等级患者术后疼痛程度(VAS评分)、伤椎局部后凸角(Cobb角)、骨折复位[伤椎前缘高度比(FVHR)]、椎体高度丢失率,分析骨水泥弥散分布等级与术后各指标的相关性。结果:不同骨水泥弥散分布等级OVCF患者VAS评分、Cobb角比较,差异无统计学意义(P>0.05)。术后1 d、1周及1个月,不同骨水泥弥散分布等级患者FVHR、椎体高度丢失率比较,差异有统计学意义(P<0.05);术后1周及1个月,患者FVHR较术后1 d升高(P<0.05),椎体高度丢失率较术后1 d降低(P<0.05);术后各时点患者FVHR、椎体高度丢失率比较,差异有统计学意义(P<0.05)。相关性分析显示,骨水泥弥散分布等级与OVCF患者FVHR呈正相关(r=0.521,P<0.05),与椎体高度丢失率呈负相关(r=-0.427,P<0.05)。结论:骨水泥弥散分布等级与骨质疏松性脊柱骨折患者骨折复位、术后椎体高度丢失存在相关性,术后评估OVCF患者骨水泥弥散分布等级有助于手术疗效的判断。Objective:To explore the relationship of bone cement dispersion level with fracture reduction and postoperative vertebral height loss in patients with osteoporotic vertebral compression fractures(OVCF).Methods:50 patients with OVCF were selected as the research subjects.According to the dispersion distribution of bone cement, the patients were divided into grade Ⅰ(n=16),grade Ⅱ(n=20) and grade Ⅲ(n=14),all patients were treated with percutaneous vertebroplasty or percutaneous kyphoplasty.The pain degree(VAS score),local kyphosis of the injured vertebra(Cobb angle),fracture reduction [height ratio of anterior edge of injured vertebra(FVHR)] and vertebral height loss rate after operation of patients with different grades of bone cement dispersion distribution were compared, and the correlation between the grade of bone cement dispersion distribution and postoperative indexes was analyzed.Results:There was no significant difference in VAS score and Cobb angle between OVCF patients with different bone cement dispersion levels(P>0.05).There were statistically significant differences in FVHR and vertebral height loss rate between patients with different bone cement diffusion levels at 1 d, 1 w and 1 m after operation(P<0.05).The FVHR of patients with different bone cement dispersion levels were significantly higher, and the vertebral height loss rate was significantly lower at 1 w and 1 m after operation than at 1 d after operation(P<0.05).There were statistically significant differences in FVHR and vertebral height loss rate between patients with different bone cement dispersion levels at each time point after operation(P<0.05).Correlation analysis showed that the grade of bone cement dispersion level was significantly positively correlated with the FVHR of patients with OVCF(r=0.521,P<0.05),and negatively correlated with the rate of vertebral height loss(r=-0.427,P<0.05).Conclusion:There is a significant correlation between the bone cement dispersion level and fracture reduction and postoperative vertebral heigh
