下胸椎骨质疏松性压缩骨折PVP术中不同剂量骨水泥对临床疗效的影响

The effects of different doses of bone cement on the clinical efficacy in osteoporotic Lower vertebral compression fractures treated by PVP

目的观察不同剂量骨水泥对下胸椎骨质疏松性压缩骨折PVP术临床疗效的影响。方法将80例下胸椎压缩骨折患者随机均分成A和B两组,A组注入2ml骨水泥行PVP术治疗,B组注入4ml骨水泥行PVP术治疗,比较两组患者疗效。结果A组患者术后骨水泥外渗率显著小于B组(P<0.05),两组患者在椎体高度恢复、术后止痛效果差异无统计学意义(P>0.05)。结论下胸椎压缩骨折PVP术中,采用2ml剂量骨水泥注入,创伤小、疗效可靠、并发症少。

Objective To observed the effects of different doses of bone cement on the clinical efficacy in osteoporotic below vertebral compression fractures treated by PVP. Methods 80 patients with thoracic vertebra compression fractures were divided in A group and B group, A group treated by PVP with 2 ml bone cement, and B group treated by PVP with 4 ml bone cement. Then observating the clinical efficacy of the two groups. Results The bone cement leakage rate in A group was significantly better than that in B group （P〈0.05）. There were no significant differences in vertebral height restoration and postoperative analgesic effect be- tween two ~groups. Conclusion PVP intraoperative thoracic vertebra compression fractures, using 2 ml dose bone cement injection, trauma small curative effect reliable and less complications.
