摘要
目的:探讨磁共振技术在评估腰椎椎体间融合术后骨性融合的临床价值。方法:回顾性分析2012年1月-2014年6月本院收治的36例因腰椎退行性病变行腰椎椎体间植骨融合术(transforaminal lumbar interbody fusion,TLIF)患者的临床资料,收集所有患者随访2年内的X线、CT、MRI影像学资料,分析术后3个月、6个月、1年、2年不同影像学检查手段在评估椎体间融合状态的效果。结果:术后3个月、6个月、1年、2年腰椎X线、CT扫描重建、MRI所示椎间融合率为16.67%、8.33%、0,80.56%、61.11%、55.56%,97.22%、83.33%、86.11%,100%、97.22%、97.22%。术后6个月与术后3个月椎体融合率比较,腰椎X线(χ~2=29.412,P<0.05)、CT扫描重建(χ~2=22.121,P<0.05)、MRI(χ~2=27.692,P<0.05);术后1年与术后6个月椎体融合率比较,腰椎X线(χ~2=5.063,P<0.05)、CT扫描重建(χ~2=4.431,P<0.05)、MRI(χ~2=8.134,P<0.05);术后2年与术后1年椎体融合率比较,腰椎X线(χ~2=0.000,P>0.05)、CT扫描重建(χ~2=2.532,P>0.05)、MRI(χ~2=1.636,P>0.05)。相同时间点三种检查手段在椎体融合率方面比较,差异均无统计学意义(P>0.05)。结论:磁共振在评估腰椎椎体融合术后椎体骨性融合方面与CT扫描重建效果相当,优于腰椎X线片,磁共振评估可作为术后仍有症状的患者融合状态评估方法。
Objective:To evaluate the clinical value of magnetic resonance imaging in assessing bone fusion after lumbar vertebral fusion.Method:The data of 36 patients with lumbar degenerative disease who underwent transforaminal lumbar interbody fusion(TLIF)from January 2012 to June 2014 were retrospectively analyzed.All patients were followed up for 2 years,X-ray,CT,MRI imaging data were selected,the effect of interbody fusion of different imaging methods postoperative 3 months,6 months,1 year,2 years were assessed.Result:The intervertebral fusion rate of lumbar X-ray,CT scan reconstruction and MRI after 3 months,6 months,1 year and 2 years were 16.67%,8.33%,0;80.56%,61.11%and 55.56%;97.22%,83.33%,86.11%;100%,97.22%,97.22%.After 3 months compared with 6 months,the intervertebral fusion rate of lumbar X-ray(χ2=29.412,P<0.05),CT scan reconstruction(χ2=22.121,P<0.05),MRI(χ2=27.692,P<0.05).After 1 year compared with 6 months,the vertebral fusion rate of lumbar X-ray(χ2=5.063,P<0.05),CT scan reconstruction(χ2=4.431,P<0.05),MRI(χ2=8.134,P<0.05).After 2 years compared with 1 year,the vertebral fusion rate of lumbar X-ray(χ2=0.000,P>0.05),CT scan reconstruction(χ2=2.532,P>0.05),MRI(χ2=1.636,P>0.05).There was no significant difference in vertebral fusion rate among the three methods at the same time point(P>0.05).Conclusion:Magnetic resonance imaging(MRI)is superior to lumbar radiographs in assessing vertebral bone fusion after lumbar vertebral fusion.Magnetic resonance imaging can be used as a method for assessing the fusion status of patients with postoperative symptoms.
