球囊扩张椎体成形术中填充人工骨与骨水泥治疗椎体压缩性骨折疗效比较

目的回顾性分析球囊扩张椎体成形术中填充人工骨与骨水泥治疗椎体压缩性骨折疗效比较。方法对30例（31个骨折椎体）随访1年以上资料完整的脊柱压缩骨折患者进行回顾性分析（平均随访时间1．7年），A组15例患者填充硫酸钙骨水泥（CSC），B组填充骨水泥，分析术前、术后患者视觉模拟评分（VAS）、Oswestry功能障碍指数及骨折椎体高度恢复。结果A、B两组患者术后VAS疼痛评分、Oswestry功能障碍指数与术前比较均较术前明显改善（P〈0．05）；A组和B组骨折椎体高度与术前比较均较术前明显改善（P〈0．05），两组术后结果与1年后随访比较无显著性差异；组间比较无统计学差异。结论硫酸钙治疗椎体压缩骨折同样可以取得骨水泥治疗骨质疏松性椎体骨折的疗效，能完全或部分缓解患者的疼痛及提高患者脊柱功能活动；恢复骨折椎体的高度避免骨折椎体高度进一步丢失。

A comparative study on clinical outcomes of balloon kyphoplasty with calcium sulfate cement and bone cement for vertebral compression fractures

Objective To analyze retrospectively the clinical outcomes of balloon kyphoplasty with calcium sulfate cement （CSC） and bone cement for vertebral compression fractures. Methods The complete data of 30 patients （31 fractured vertebral bodies） with vertebral compression fractures who were followed up for a mean period of 1.7 years were retrospectively analyzed. These patients were divided into 2 groups： group A （with CSC） and group B （with bone cement）, with 15 patients in each group. Preoperative and postoperative clinical evaluation and radiological data were analyzed, including the Visual Analog Scale （VAS） score, Oswestry Disability Index （ODI）, and vertebral body height restoration. Results Statistically significant improvements were found in the VAS score and ODI postoperatively when compared with that preoperatively in group A and group B （P〈0.05）. Statistically significant improvements were found in the vertebral body height postoperatively when compared with that preoperatively in group A and group B （/〈0.05）, and the postoperative results were not significantly different from that in the latest follow-up of 1 year after surgery. There were no statistically significant differences between group A and group B. Conclusions The CSC for vertebral compression fractures can get the same effect as the bone cement for osteoporotic vertebral fractures. It can quickly relieve pain completely or partially, improve the range of motion of the spine, restore the vertebral body height and prevent the further loss of the vertebral body height.
