【摘要】：目的： 探討脊髓型頸椎病術(shù)后脊髓受壓征象的MRI評分及改善率與術(shù)后頸椎JOA評分及改善率的相關(guān)性。 方法： 回顧性分析2010年1月—2012年12月在吉林大學(xué)白求恩第二醫(yī)院就診的30例行頸椎手術(shù)治療的多節(jié)段脊髓型頸椎病患者頸椎術(shù)前、術(shù)后MRI資料，所有患者均行術(shù)前、術(shù)后JOA評分�；颊吣挲g45-73歲，平均57.1±8.9歲，其中男18例，，女12例。依據(jù)脊髓型頸椎病脊髓受壓征象MRI評分系統(tǒng)對其術(shù)前、術(shù)后6個月MRI進(jìn)行評分（總分最高30分，最低0分，分?jǐn)?shù)越高表明影像學(xué)受壓程度越嚴(yán)重），并計算脊髓受壓征象改善率（（術(shù)前分?jǐn)?shù)-術(shù)后分?jǐn)?shù)）/術(shù)前分?jǐn)?shù)×100%）。分析術(shù)后脊髓受壓征象MRI評分與術(shù)后JOA評分的相關(guān)性；及術(shù)后脊髓受壓征象MRI評分改善率與術(shù)后JOA評分改善率的相關(guān)性。 結(jié)果： 隨訪時間6個月，30例患者JOA評分從術(shù)前的平均9.3±2.4分，增加到術(shù)后的12.9±1.8分，JOA評分改善率為47.4±14.7%；脊髓受壓征象MRI評分由術(shù)前平均10.5±3.9，減少到術(shù)后平均6.1±2.7，MRI評分改善率為40.8±15.9%。術(shù)后MRI評分與JOA評分進(jìn)行Spearman相關(guān)性分析，相關(guān)系數(shù)為-0.699，P0.01，呈顯著性負(fù)相關(guān)。術(shù)后MRI評分改善率與JOA評分改善率進(jìn)行Spearman相關(guān)性分析，相關(guān)系數(shù)為0.376，P=0.041（0.05），呈顯著性正相關(guān)。 結(jié)論： 脊髓型頸椎病脊髓受壓征象MRI評分系統(tǒng)不僅可評價脊髓型頸椎病術(shù)后影像學(xué)改善情況，而且可以有效地預(yù)測臨床預(yù)后。
[Abstract]:Objective: to investigate the correlation between MRI score and improvement rate of spinal cord compression after cervical Spondylotic myelopathy (cervical Spondylotic myelopathy). Methods: the MRI data of 30 patients with multilevel cervical Spondylotic myelopathy treated by cervical surgery from January 2010 to December 2012 in Bethune Hospital of Jilin University were analyzed retrospectively. All patients received preoperative and postoperative JOA scores. The age of the patients was 45-73 years (mean 57.1 鹵8.9 years), including 18 males and 12 females. According to the MRI scoring system of spinal cord compression sign of cervical Spondylotic myelopathy, the MRI was evaluated before and 6 months after operation (total score was highest 30 points, lowest 0 point). The higher the score was, the more severe the imaging compression was. The improvement rate of spinal cord compression was calculated (preoperative fracture-postoperative score) / preoperative score 脳 100%. To analyze the correlation between the MRI score of postoperative spinal cord compression sign and the postoperative JOA score, and the correlation between the improvement rate of MRI score of postoperative spinal cord compression sign and the improvement rate of postoperative JOA score. Results: the average JOA score of 30 patients was increased from 9.3 鹵2.4 before operation to 12.9 鹵1.8 after operation. The improvement rate of JOA score was 47.4 鹵14.7. The MRI score of spinal cord compression was decreased from 10.5 鹵3.9 before operation to 6.1 鹵2.7 postoperatively. The improvement rate was 40.8 鹵15.9. The correlation between MRI score and JOA score was analyzed by Spearman, the correlation coefficient was-0. 699g / P 0. 01, there was a significant negative correlation between Spearman score and JOA score. The improvement rate of MRI score and the improvement rate of JOA score were analyzed by Spearman correlation analysis after operation. The correlation coefficient was 0. 376 and 0. 041 (0. 05), and there was a significant positive correlation between the improvement rate of MRI score and the improvement rate of JOA score. Conclusion: MRI scoring system can not only evaluate the imaging improvement of cervical Spondylotic myelopathy, but also predict the clinical prognosis.
