文题释义:
Pfirrmann分级系统:由瑞士学者Pfirrmann CW于2001年提出。根据椎间盘在核磁共振 T2像中的形态学表现(髓核信号改变、髓核与纤维环分界清晰程度以及椎间高度改变)将椎间盘退变分为5级,其中1至2级为正常椎间盘,3-5级为退变椎间盘。Pfirrmann评估系统科学简便,组间一致性Kappa值为0.69-0.81,组内一致性Kappa值为0.84-0.90,为目前使用最广泛的椎间盘退变核磁共振评估系统。
X射线九分法评估系统:Walraevens等基于X射线矢状位颈椎的相关参数(椎间盘高度缺失,椎体前缘骨赘形成,终板硬化程度)提出了颈椎间盘退变的“X射线九分法评分系统”,其具有良好的组间、组内协议一致性,且相较于核磁共振,X射线检查更加便利、快捷,更适用于普遍筛查及随访评估工作。
 
摘要
背景:X射线九分法评分系统基于颈椎间盘退变建立,其是否适用于腰椎间盘退变评估尚未验证。
目的:验证X射线九分法评估腰椎间盘退变的可行性,探讨其临床应用价值。
方法:借助核磁共振Pfirrmann 分级系统进行验证,统计学分析X射线九分法与Pfirrmann评分法的相关性。回顾性分析2013年6月至2016年6月在上海长征医院诊治的172例腰椎退变或单纯腰痛患者的影像学资料。所有患者退变椎间盘的核磁共振表现按Pfirrmann评估标准进行评价,X射线表现按九分法评估标准进行评价。评价得出的2组评分数据借助SPSS软件,经Spearman秩和检验进行相关性及回归分析。
结果与结论:①核磁共振Pfirrmann评分(自变量X):1分2例,2分8例,3分55例,4分84例,5分23例;X射线九分法评分(因变量Y):0分2例,1分6例,2分21例,3分43例,4分40例,5分26例,6分16例,7分8例,8分7例,9分3例;②经Spearman相关性检验证明Pfirrmann评分和九分法评分呈显著正相关(P < 0.01)。对相关系数进行显著性检验,得出Pfirrmann评分与九分法评分的线性相关关系显著。进一步的回归分析结果显示Pfirrmann评分与九分法评分有直线回归关系;③结果表明,X射线九分法与Pfirrmann评分法评估腰椎间盘退变一致性好;X射线九分法作为一种科学、快捷、有效的评估手段,对腰椎间盘退变性疾病的诊断具有一定的参考价值。

Abstract:

BACKGROUND: The X-ray 9-point grading system is established based on cervical disc degeneration and its suitability for evaluation of lumbar disc degeneration has not been validated.

OBJECTIVE: To investigate the feasibility of the evaluation of lumbar intervertebral disc degeneration using the 9-point grading system with X-ray, and to explore its clinical application value. 
METHODS: The correlation between 9-point grading system and Pfirrmann system was statistically analyzed. Magnetic resonance imaging (MRI) and X-ray images of 172 cases with lumbar disc degeneration or simple lumbago, who were treated in the Shanghai Changzheng Hospital from June 2013 to June 2016, were retrospectively analyzed. The MRI scores of lumbar disc degeneration were evaluated according to Pfirrmann standard, and the X-ray scores were evaluated according to 9-point grading system. The two groups of scores were respectively analyzed by the correlation and regression tests via Spearman rank sum test with SPSS software. 
RESULTS AND CONCLUSION: (1) MRI scores (the independent variable X): 2 cases scored 1; 8 cases scored 2; 55 cases scored 3; 84 cases scored 4; 23 cases scored 5. X-ray scores (the dependent variable Y): 2 cases scored 0; 6 cases scored 1; 21 cases scored 2; 43 cases scored 3; 40 cases scored 4; 26 cases scored 5; 16 cases scored 6; 8 cases scored 7; 7 cases scored 8; 3 cases scored 9. (2) The Spearman correlation test showed that significant positive correlation was found between Pfirrmann system and 9-point grading system (P < 0.01). Significance test of correlation coefficient proved that there was significant linear correlation between Pfirrmann system and 9-point grading system. Further regression analysis showed the linear regression between Pfirrmann system and 9-point grading system. (3) These findings suggested that Pfirrmann system and X-ray 9-point grading system had a good consistency in evaluating lumbar disc degeneration. As a scientific, fast and effective evaluation method, the X-ray 9-point grading system has a certain reference value in the diagnoses of lumbar degenerative diseases.
