Abstract:

 Objective To evaluate the clinical effect of a kind of balloon kyphoplasty（C-pod kyphoplasty）in the treatment of osteoporotic thoracic vertebral compression fractures. Methods From December 2014 to March 2016, 21 cases of osteoporotic vertebral compression fractures in 25 vertebral bodies were treated with catheter fabrickyphoplasty. VAS and ODI were recorded before operation and within 24 hours after operation and the last follow?up. The changes of vertebral kyphosis Cobb angle were measured before operation and after operation and at the last follow?up. Results All cases were followed up 6 to33 months（average 15.3 months）. Before the operation, the VAS score was 7.6 ± 1.2, the ODI score was 87.4±11.5, and the cobb was 21±4.6. In 24 hours after the operation, the VAS score was 2.4± 0.6, the ODI score was 43.8±9.6, and the cobb was 5.8±0.6. In the final follow?up, the VAS score was 2.1±0.4, the ODI score was 42.6±10.1, and the cobb was 6.4±0.7.The VAS, ODI score and Cobb angle were significantly improved after operation and in the last follow-up, the differences were statistically significant. There was no significant difference in VAS, ODI score and Cobb angle between 24 hours after operation and the last follow-up. Conclusion The curative effect of C-pod kyphoplasty was good and in treating osteoporotic thoracic vertebral fracture. It can reduce the leakage of bone cement during the operation.

摘要：

目的 评估编织囊袋椎体后凸成形术（CFKP）治疗骨质疏松性胸椎体压缩骨折的临床效果。方法 2014年12月至2016年3月，应用编织囊袋椎体后凸成形术治疗骨质疏松性胸椎体压缩骨折21例，共25个椎体。术前、术后24h内及末次随访时评估VAS及ODI；测量术前、术后及末次随访的椎体后凸cobb角度变化。结果 术后随访6～33个月（平均15.3个月），术前VAS评分7.6±1.2、ODI评分87.4±11.5、cobb角21±4.6、术后24hVAS评分2.4±0.6、ODI评分43.8±9.6、cobb角5.8±0.6；末次随访VAS评分2.1±0.4、ODI评分42.6±10.1、cobb角6.4±0.7；末次随访时的VAS、ODI评分、cobb角分别与术前比较明显改善，差异均有统计学意义（P<0.05）；而术后24h的VAS、ODI评分、cobb角与末次随访比较，差异均无统计学意义。结论 编织囊袋椎体后凸成形术治疗骨质疏松性胸椎压缩骨折临床效果满意，可以减少骨水泥渗漏。
