椎体后凸成形术对压缩性骨折椎体高度恢复及缓解疼痛的疗效探讨

目的探讨椎体后凸成形术在治疗骨质疏松性椎体压缩性骨折时恢复椎体高度以及缓解疼痛方面的疗效。方法对12例19个压缩性骨折椎体进行治疗后，对术前、术后即刻以及术后4、12周记录视觉模拟量表（VAs）进行评分。在术后x线检查中对椎体高度恢复进行评估。结果患者的平均术前视觉模拟量表评分为9．3，但在术后改善至5．4。在术后4、12周，平均视觉模拟量表评分分别为5．1、5．9。所有患者在24h内恢复日常活动。患者椎体高度的恢复以椎体前部和中部明显。结论在疼痛缓解和恢复椎体高度方面，椎体后凸成形术对于骨质疏松性椎体压缩性骨折患者是安全和有效的治疗方法。

Pain outcome and vertebral body height restoration in patients undergoing kyphoplasty

Objective To study the pain outcome and vertebral body height restoration in treatment of osteoporotic vertebral compression fractures （VCF） by kyphoplasty. Methods The data of 12 patients treated with kyphoplasty were retrospectively reviewed. A total of 19 vertebral levels were augmented. Visual analog scale （VAS） scores were documented in the immediate pre- and postoperative period, as well as 4, 12 weeks after the procedure.Vertebral body height restoration was assessed on postoperative X-rays. Results Mean preoperative VAS score was 9. 3 and improved to 5.4 in the immediate postoperative period. At 4, 12 weeks postoperatively, mean VAS scores were 5.1,5.9 respectively. All patients returned to their daily activities within 24 hours. Vertebral body height restoration was obvious in the anterior and middle portion of the vertebral body. Conclusion In regards to pain relief and postoperative functional outcome, kyphoplasty is a safe and effective treatment modality for osteoporotic VCFs.
