单侧椎体后凸成形术治疗骨质疏松性椎体压缩骨折长期疗效观察

Long Term Clinical Results Investigation of Osteoporotic Vertebral Compression Fractures Treated by Unilateral Kyphoplasty

目的探讨单侧椎体后凸成形术治疗骨质疏松性压缩骨折的安全性及有效性。方法选择保定市第一中心医院2005年9月至2010年7月应用单侧椎体后凸成形术治疗的骨质疏松性压缩骨折患者40例(57个椎体),对术后骨水泥渗漏,椎体高度恢复程度,1个月模拟视觉评分(VAS)及日常活动能力进行评估。结果 H本组40例患者均获得随访,平均23个月。术后椎体高度较术前明显增加(P<0.05)、骨水泥渗漏至椎体周围软组织渗漏率为18%,无骨水泥渗漏相关并发症的发生。术前、术后即刻及术后1个月VAS评分比较差异有统计学意义(P<0.01);所有患者在治疗数小时后恢复日常活动。结论单侧椎体后凸成形术是治疗骨质疏松性椎体压缩骨折安全而有效的治疗方法。

Objective To investigate safety and efficacy of osteoporotie vertebral compression fractures treated with unilateral kyphoplasty. Methods Forty cases （57 vertebral bodies） of osteoporotic vertebral compression fractures treated by unilateral kyphoplasty in Baoding First Central Hospital from Sep. 2005 to Jul. 2010 were collected. Cement leakage after operation, restoration of vertebral body（ VB ） height, 1 -month postoperative visual analog scale （VAS） pain scores, and daily activity levels were assessed. Results The forty patients were followed up for 23 months on average. The vertebral body height after operation increased comprarlng with preoperation （P 〈 0. 05 ）, cement leakage into the paravertebral soft tissues occurred in 18% of the patients, no complications related to cement leakage were noted. The mean preoperative VAS score, the immediate and early postoperative VAS score were statistically significantly different（ P 〈 0. 01 ）. All patients resumed routine activities within hours of the procedure. Conclusion Unilateral kyphoplasty is a safe and effective treatment for osteoporotic vertebral compression fractures.
