文题释义:
椎体压缩性骨折及骨水泥椎体成形:椎体压缩性骨折是最常见且最严重的骨质疏松症并发症,常见于胸腰段的椎体,其发生率随年龄的增长而增加,临床表现主要是脊柱出现进行性加重的后凸畸形与疼痛,但多不伴有下肢的神经症状,严重者需手术治疗;而骨水泥椎体成形是治疗骨质疏松性椎体压缩性骨折的有效方法之一,将骨水泥均匀填充于患处,以恢复患椎的椎体前缘高度并纠正脊柱的后凸与侧凸畸形,疗效确切。
骨水泥的渗漏:主要通过2种途径,或者是经有缺损的椎体外壁(局部渗漏)或者是经椎体静脉丛(远处)。还有因术中操作不当引起的医源性渗漏。大多数骨水泥渗漏不会引起临床症状,只有少数会引起临床症状。常见的经椎体外壁的渗漏包括:椎间盘渗漏、椎管内渗漏、椎旁软组织渗漏、椎旁静脉丛渗漏等。
 
 
背景:椎体成形是微创治疗骨质疏松性椎体压缩性骨折的有效方法之一,骨水泥是最常用的填充材料,但不同黏度骨水泥填充的临床疗效存在争议。
目的:比较不同黏度骨水泥椎体成形系统治疗骨质疏松性椎体压缩性骨折的疗效与安全性。
方法:将183例骨质疏松性椎体压缩性骨折的患者随机分为4组,高黏度骨水泥经皮椎体成形组、低黏度骨水泥经皮椎体成形组、高黏度骨水泥经皮椎体后凸成形组以及低黏度骨水泥经皮椎体后凸成形组。

结果与结论:①与经皮椎体成形高黏度骨水泥组相比,经皮椎体成形低黏度骨水泥组手术时间及X射线暴露时间较长;而与经皮椎体后凸成形高黏度骨水泥组相比,经皮椎体后凸成形低黏度骨水泥组手术时间及X射线暴露时间较长;②与置入前相比,各组置入后随时间的延长目测类比评分和功能障碍指数评分逐渐降低,且与经皮椎体成形高黏度骨水泥组相比,经皮椎体后凸成形高黏度骨水泥组功能障碍指数评分较低,与经皮椎体成形低黏度骨水泥组相比,经皮椎体后凸成形低黏度骨水泥组功能障碍指数评分较低;③与置入前相比,各组置入后随时间的延长后凸Cobb角逐渐减小,伤椎的矢状面指数逐渐增加;与经皮椎体成形高黏度骨水泥组相比,经皮椎体后凸成形高黏度骨水泥组和经皮椎体后凸成形低黏度骨水泥组后凸Cobb角较小,且经皮椎体后凸成形低黏度骨水泥组后凸Cobb角小于经皮椎体后凸成形高黏度骨水泥组;④经皮椎体后凸成形高黏度骨水泥组和经皮椎体成形高黏度骨水泥组不良反应发生率较低;⑤提示使用高黏度骨水泥治疗骨质疏松性椎体压缩性骨折安全性与有效性较好,且高黏度骨水泥经皮椎体后凸成形系统的临床疗效最佳。

Abstract:

BACKGROUND: Vertebroplasty is one of the effective methods for minimally invasive treatment of osteoporotic vertebral compression fractures. Bone cement as the most commonly used filling material is disputed on its clinical effects of different viscosity.

OBJECTIVE: To compare the efficacy and safety of different viscosity bone cement vertebroplasty in the treatment of osteoporotic vertebral compression fractures.
METHODS: One hundred and eighty-three patients with osteoporotic vertebral compression fracture were randomly divided into four groups: percutaneous vertebroplasty with high viscosity bone cement group (group A), percutaneous vertebroplasty with low viscosity bone cement group (group B), percutaneous kyphoplasty with high viscosity bone cement group (group C), and percutaneous kyphoplasty with low viscosity bone cement group (group D).

RESULTS AND CONCLUSION: (1) The operative time and X-ray exposure time were longer in the two low viscosity bone cement groups than the two corresponding high viscosity bone cement groups, respectively. (2) After operation, visual analogue scale scores and disability index scores were gradually decreased in the all the groups. Compared with the group A, the visual analogue scale score and disability index score were lower in the group C; compared with group B, the visual analogue scale score and disability index score were lower in the group D. (3) After operation, the kyphosis Cobb angle was gradually reduced and the sagittal index of injured vertebrae were gradually increased in all the groups. The postoperative Cobb angle value was ranked as follows: group A > group C > group D. (4) Compared with two low viscosity bone cement groups, two high viscosity bone cement group had lower incidence of adverse events. These findings indicate that high viscosity bone cement has better safety and effectiveness in the treatment of osteoporotic vertebral compression fractures. The clinical efficacy of percutaneous kyphoplasty with high viscosity bone cement is the best among the four systems.
