摘要： 目的探讨颈椎后纵韧带骨化症(OPLL)临床表现与影像学特点之间的相关性。方法2008 年9 月~2010 年11 月多中心搜集200 例OPLL 患者的影像学资料及临床特点(JOA评分)，参照颈椎正中矢状位CT 计算OPLL 椎管占位率，同时对OPLL 患者进行分型及观察骨化椎体情况。对OPLL 占位率与JOA 评分数据进行相关分析。结果OPLL 椎管占位率为19.8%~60.3%，平均42.9%；JOA 评分4~15 分，平均10 分。线性回归显示，OPLL 椎管占位率与JOA 评分呈负相关(P<0.01)。节段型94 例，混合型46例，连续型23 例，局灶型37 例，C3和C4椎体骨化次数最多。结论OPLL 的临床表现与椎管占位率有密切关系，椎管占位率越大，临床症状越严重。C3、C4为最常见骨化椎体，有脊髓压迫症状的OPLL 以节段型常见。

Abstract: Objective To explore the relationship of the radiological characteristics and clinical symptoms of ossification of the posteriorlongitudinal ligament (OPLL) of cervical spine. Methods 200 OPLL patients were recruited into this study. The data of JOA scores of theOPLL patients were collected. The stenotic rate of the cervical spine canal was calculated by the sagittal plane CT. The sorts and ossificatedcervicle were also identified by the images. Results The stenotic rate of the cervical spine canal was 19.8% to 60.3% with average 42.9%,the JOA scores was 4 to 15, averaged 10. Linear regression showed the stenotic rate of the cervical spine canal was negatively correlatedwith the JOA scores (P<0.01). There were 94 cases for segmental-type, 46 for mixed-type, 23 for continuous-type and 37 for focal-type. Thethird and fourth cervical vertebrae were susceptible to ossify. Conclusion The higher the OPLL occupation ratio, the worse the clinicalOPLL symptoms. The OPLL patients following clinical symptoms with spinal cord oppression are more likely the segmental-type.
