球囊扩张椎体成形术治疗骨质疏松型椎体压缩骨折

Balloon kyphoplasty in treating osteoporotic vertebral fractures

目的:评价球囊扩张椎体成形术治疗骨质疏松型椎体压缩骨折的临床疗效。方法:对52例82个骨质疏松型压缩骨折的椎体,采用球囊扩张椎体成形术进行治疗。测量术前和术后椎体高度、Cobb′s角、术前和术后VAS评分并进行统计学分析。结果:平均随访9个月(37周,4～99周);椎体前柱和中柱分别增高了4.6、3.9mm(P<0.05);Cobb′s角增加了3.4°(P<0.05);VAS评分增加了7分(P<0.05);术后无不良反应和并发症;骨水泥外渗率为9.8%。结论:球囊扩张椎体成形术治疗骨质疏松型椎体压缩骨折安全有效,可恢复椎体高度,改善患者的生活质量。

Objectives： To evaluate the effect of balloon kyphoplasty. Methods： Retrospective analysis of the first 52 patients with 82 painful vertebral body compression fractures secondary to osteoporosis treated at our institution. Results： Mean length of follow-up was 9 months （37 weeks, range 4-99 weeks）; improved height 4.6 and 3.9 mm in the anterior and medial columns, respectively （P〉0.05） ; Cobb angle increased 3.4° （P 〈0.05）, visual analogue pain scale score improved 7 points （P d〈.05） ; no adverse medical or procedural complications; 9. 8% cement leakage rate. Conclusion： Balloon kyphoplasty safely improves vertebral body height and patient＇s quality of life.
