摘要:

背景:经皮椎体成形治疗是针对骨质疏松性椎体压缩骨折一种有效的微创疗法,但在临床应用过程也存在一定的不足,如不能恢复椎体高度及矫正局部后凸畸形,同时骨水泥渗漏发生率较高。
目的:评价脊柱外固定器撑开复位结合椎体成形治疗骨质疏松性椎体骨折的近期临床疗效。
方法:2012年1月至2013年6月采用脊柱外固定器撑开复位结合椎体成形治疗骨质疏松性严重椎体骨折患者55例。术中先采用经皮椎弓根钉脊柱外固定器撑开闭合复位矫正脊柱后凸畸形,然后再经皮穿刺行伤椎椎体成形治疗。测量治疗前后压缩骨折椎体高度压缩率、后凸畸形角度及椎管内狭窄占位率。同时采用目测类比评分法和Oswestry功能障碍指数评估临床疗效。
结果与结论:患者治疗后和末次随访时的目测类比评分和Oswestry功能障碍指数与治疗前比较均明显改善 (P < 0.05),患者腰背痛基本缓解,治疗后1-3 d可下床活动。55例共57个椎体出现骨水泥渗漏4例,但无明显临床症状。经脊柱外固定器整复结合椎体成形治疗后和末次随访时的压缩骨折椎体高度、后凸畸形角度及椎管内狭窄占位率均较治疗前显著改善(P < 0.05),治疗后与末次随访相比差异无显著性意义。提示脊柱外固定器撑开复位结合经皮椎体成形治疗骨质疏松性严重椎体骨折是一种安全有效且疗效稳定的微创修复方法,骨水泥渗漏率低,可获得满意的脊柱稳定性。

Abstract:

BACKGROUND: Percutaneous vertebroplasty is an effective minimally invasive method in the treatment of osteoporotic vertebral compression fractures. However, there are some shortcomings during clinical application, such as cannot recover vertebral height or correct local kyphosis, as well as the incidence of cement leakage is very high.
OBJECTIVE: To evaluate the latest clinical effect of spinal external fixator distraction reduction combined with vertebroplasty for osteoporotic vertebral fractures. 
METHODS: From January 2012 to June 2013, 55 sever osteoporotic fracture patients accepted the treatment of spinal external fixator distraction reduction combined with vertebroplasty. During the operation, we firstly used percutaneous pedicle screw fixator to open the closed reduction and to correct the kyphosis, followed by vertebroplasty via percutaneous puncture. Then we measured the compression rate of vertebral body of compression fracture, the kyphosis angle and the rate of intraspinal occupancy before and after operation. Meanwhile, we evaluated the clinical effect with Visual Analogue Scale and Oswestry disability index.
RESULTS AND CONCLUSION: Visual Analogue Scale scores and Oswestry disability index were significantly improved after treatment and during final follow-up (P < 0.05). Low back pain was basically relieved. The patients  could do out-of-bed activity at 1-3 days after treatment. Among the 57 vertebral bodies of 55 cases, 4 suffered from the cement leakage without obvious clinical symptoms. The height of vertebral compression fracture, the kyphosis angle, and the rate of intraspinal occupancy were significantly improved after the spinal external fixator combined with vertebroplasty and during the last follow-up (P < 0.05), and no significant difference was detected between postoperation and final follow-up. These data indicated that spinal external fixator distraction reduction combined with percutaneous vertebroplasty for severe osteoporotic vertebral compression fractures is a safe effective minimally invasive method with stable therapeutic effects. Cement leakage rate was low, and spinal stability was satisfactory.
