摘要
目的：探讨颈椎后纵韧带骨化症（OPLL）患者脊髓压迫程度与髓内高信号（ISI）之间的关系。方法92例颈椎OPLL患者分为3组：椎管矢状径残余率≥66.7%为A组（n=29），椎管矢状径残余率33.3%~66.7%为B组（n=36），椎管矢状径残余率〈33.3%为C组（n=27）。分析各组神经功能及髓内高信号发生情况。结果 A组6例出现ISI （20.7%），B组17例出现ISI （47.2%），C组19例出现ISI （70.4%）（P〈0.05）。日本骨科协会（JOA）评分A组平均为（7.1±2.1），B组为（6.0±1.8），C组为（5.6±2.0）（P〈0.05）。结论 OPLL患者脊髓压迫程度越重，脊髓内越容易出现高信号，神经受损症状越严重。
Objective To investigate the correlation of spinal canal stricture and intramedullary increased signal intensity （ISI） in pa-tients with ossification of the posterior longitudinal ligament （OPLL）. Methods 92 patients with OPLL were divided into 3 groups, those with the sagittal diameter remained≥66.7%were as group A, 33.3%~66.7%as group B, and〈33.3%as group C. The incidence of intramed-ullary ISI was recorded, and their neurological condition was assessed with the Japanese Orthopedics Association Assessment （JOA）. Re-sults ISI were found in 6 cases in the group A （20.7%）, 17 cases in the group B （47.2%） and 19 cases in the group C （70.4%） （P〈0.05）. The score of JOA was （7.1±2.1） in the group A, （6.0±1.8） in the group B and （5.6±2.0） in the group C （P〈0.05）. Conclusion The incidence of in-tramedullary ISI increased with the severity of spinal canal stricture, and with more severe nerve damage in OPLL patients.
