武汉大学人民医院骨科 湖北 武汉 430060 目的:评价前路减压治疗颈椎骨质疏松性骨折的早期临床疗效及
其对血清中基质金属蛋白酶-3(M M P-3)和白细胞介素-6(I L-6)表达水平
的影响。方法:对48例颈椎骨质疏松性骨折采用前路减压手术治疗,
术前、术后J O A评分、C o b b's角测量评价临床疗效,采取静脉血检测术
前、术后的血清M M P-3与I L-6水平。结果:治疗预后优良率为91.7%,术
后J O A评分与伤椎高度比显著升高,C o b b角和椎管占位率明显下降,术
后的血清M M P-3与I L-6值都明显降低,手术前后对比差异有统计学意义
(P<0.05)。术后随访6个月,浅表感染、内固定断裂及颈椎不稳等并发
症发生率为4.16%。结论:前路减压治疗颈椎骨质疏松性骨折的预后效
果佳,能充分减压,迅速恢复颈椎稳定性,改善脊柱功能,安全性高,
其有效降低血清MMP-3与IL-6水平可能是其发挥临床疗效的机制之一。

Abstract
Objective. To investigate the efficacy of anterior decompression on osteoporotic cervical fractures and its effect on
inflammatory cytokines.
Methods. A total of 48 cases of cervical osteoporotic fractures were treated with anterior decompression.The clinical
efficacy was evaluated by JOA scores,height ratio of the injured vertebral body,Cobb angle,canal volume occupying
ratio,serum levels of MMP-3 and IL-6.
Results. The rate of excellent prognosis in the treatment group was 91.7%.JOA scores and height ratio of the injured
vertebral body significantly increased,while the Cobb angle and canal volume occupying ratio,MMP-3 and IL-6 levels in
the serum significantly decreased(P<0.05).During the six-month follow-up,the rate of complications such as superficial
infection,screw breakage and cervical instability was 4.16%.
Conclusion. The effect of anterior decompression on osteoporotic cervical fratures and inflammatory cytokines is
positive with complete decompression,reduction of cervical stability and improviong spinal function.Effectively reducing
the serum levels of MMP-3 and IL-6 may be one of the mechanisms of its clinical effectiveness.
