目的 研究胸腰椎骨质疏松性椎体压缩性骨折（OVCF）经皮椎体成形术（PVP）后腰背部疼痛缓解情况与骨水泥弥散分布的相关性。方法 选取2021年1月—2023年12月金沙县中医医院和毕节市第三人民医院185例因骨质疏松症导致的胸腰椎OVCF行PVP后的患者,根据术后胸腰椎正侧位X线片显示的骨水泥分布情况分为两组：骨水泥分布充分组（n=101例）和骨水泥分布不良组（n=84）, 两组均行PVP, 均行双侧穿刺入路。统计分析两组患者术前、术后及术后1周、3个月、6个月视觉模拟评分（VAS）、患者起床时间等情况。结果 185例患者术后随访半年, 骨水泥分布充分组101例, 骨水泥分布不良组84 例, 两组术后VAS评分均较前缓解（P<0.05）, 术后及术后1周、3个月、6个月的随访中分布充分组VAS评分分别为（7.17±0.76）（2.11±1.04）（1.4±0.78）（0.36±0.58）（0.05±0.22）分, 优于分布不良组（7.14±0.79）（2.37±0.79）（1.89±0.82）（0.68±0.76）（0.25±0.62）分（P<0.05）。结论 骨水泥的分布在一定程度上决定了PVP后患者腰背部残余痛的程度。尤其是骨水泥在椎体内均匀分布时, 可降低术后腰背疼痛的发生率。

Objective To study the relationship between pain relief situation in the lower back and bone cement distribution after percutaneous vertebroplasty（PVP）of thoracolumbar osteoporotic vertebral compression fracture（OVCF）．Methods A total of 185 patients with thoracolumbar OVCF caused by osteoporosis underwent PVP from January 2021 to December 2023 were selected in Jinsha County Hospital of Traditional Chinese Medicine and the Third People’s Hospital of Bijie City．Based on the distribution of bone cement shown in the anteroposterior and lateral X ray films of the thoracolumbar after the operation, they were divided into the group with adequate bone cement distribution（n=101 cases）and the group with poor bone cement distribution（n=84）．Both groups underwent PVP and bilateral puncture approaches．The Visual Analogue Scale（VAS）scores of the two groups of patients before the operation, after the operation, 1 week, 3 months, and 6 months after the operation, as well as the leaving bed time of the patients,were statistically analyzed．Results A total of 185 patients were followed up for half a year after the operation．There were 101 cases in the group with adequate bone cement distribution, and 84 cases in the poor distribution of bone cement group, There was no statistically significant difference in the preoperative general data between the two groups of patients（P>0.05）, and the postoperative VAS scores of both groups were decreased compared with those before operation（P<0.05）．The VAS scores of the adequate distributed group after the operation and in the follow-ups in 1 week, 3 months, and 6 months after the operation were（7.17±0.76）,（2.11±1.04）,（1.4±0.78）,（0.36±0.58） ,and（0.05±0.22）, respectively,better than the poor distribution group （7.14±0.79）,（2.37±0.79）,（1.89±0.82）,（0.68±0.76）,（0.25±0.62）, P<0.05．Conclusions The distribution of bone cement determines to a certain extent the degree of residual pain in the low back of patients after PVP．Especially when the bone cement is evenly distributed within the vertebral body, the incidence of postoperative low back pain can be reduced．

目的 比较唑来膦酸对 PVP(椎体成形术)治疗OVCF(骨质疏松椎体压缩性骨折)术后再发骨折的影响。方法 收集2016年12月—2018年6月在我院骨科接受PVP治疗患者共70例,其中40人在术后接受了唑来膦酸治疗(观察组),30人在术后接受了安慰剂治疗(对照组),两组患者均给予维生素D和钙剂基础治疗。记录术后6个月、1年、2年腰椎骨密度;术后2年内伤椎及邻近椎体再发骨折情况。结果 观察组伤椎再发骨折率(1/40,2.5%)低于对照组(2/30,6.67%)(P＜0.05);观察组邻椎再发骨折率(2/40,5%)低于对照组(7/30,23.33%)(P＜0.05)。结论 唑来膦酸能较好地预防PVP术后再发骨折。

Objective To compare the effect of zoledronic acid on the treatment of osteoporotic vertebral compression fracture after percutaneous vertebroplasty PVP. Methods From December 2017 to June 2019, a total of 70 patients who received PVP in the hospital medical plastic surgery clinic, 40 patients were collected received zoledronic acid (group A) and 30 patients received placebo (group B) after operation. Both groups received basic treatment of vitamin D and calcium. The bone mineral densits (BMD) of lumbar vertebrae were recorded at 6 months, 1 year and 2 years after operation, and the recurrent fractures of injured vertebrae and adjacent vertebrae were recorded at 2 years after operation. Results The rate of recurrent fracture of vertebrae in group A (1/40, 2.5%) was lower than that in group B (2/30, 6.67%); the rate of recurrent fracture of adjacent vertebrae in group A (2/40, 5%) was grcartly lower than that in group B (7/30, 23.33%). Conclusion Zoledronic acid can prevent recurrent fracture after PVP.
