颈椎病患者后纵韧带的磁共振影像及临床意义

Magnetic resonance imaging and its clinical significance of cervical spondylosis

目的 :探讨颈椎病后纵韧带的磁共振影像特点及其临床意义。方法 :对 2 0 0 0年 4月～ 2 0 0 2年 4月的 4 2例颈椎病的磁共振影像和临床资料进行回顾性分析。结果 :磁共振检查提示后纵韧带骨化 9例 ,后纵韧带肥厚 17例 ,颈椎间盘脱出 16例。 16例行颈椎后路手术 ,2 6例行颈椎前路手术切除后纵韧带。平均改善率为 6 1.8% ,优 11例 ,占 31.4 % ;良 14例 ,占 4 0 % ;一般 8例 ,占 2 2 .9% ;差 2例 ,占 5 .7%。结论 :MRI对后纵韧带骨化、后纵韧带肥厚和颈椎间盘脱出的诊断有重要价值 ,对手术方案的选择有重要意义。

Objective:To study the magnetic resonance imaging of cervical spondylosis and its clinical significance.Methods:The magnetic resonance imaging and clinical data of 42 patients with cervical spondylosis were reviewed from April 2000 to April 2002.Results:It was deduced from MRI that there were 9 patients with ossification of posterior longitudinal ligament (OPLL),17 cases with thick posterior longitudinal ligament and 16 cases with cervical intervertebral disc extrusion. 16 patients have undergone posterior cervical operation and 26 patients anterior cervical operation and posterior longitudinal ligament resection. The mean recovery rate based on the scoring system of the Japanese Orthopedic Association (JOA) was 61.8%, 11 cases were excellent (31.4%), 14 cases were good (40%), 8 cases were fine (22.9%), 2 cases were bad (5.7%).Conclusion:MRI is of great value in the diagnosis of OPLL, posterior longitudinal ligament thickening and cervical intervertebral disc extrusion and of great significance in the choice of operation scheme.
