【摘要】 目的探讨颈椎侧位X线片测量评估退行性颈椎管狭窄的价值。方法收集近5年经健康体检的正常人群作为研究对象,共200例,男性100例,女性100例。按研究对象的年龄分为两组:青年组92例及中老年组108例。计算所有患者颈椎C3、C4、C5、C6、C7的椎管矢状径、椎体中矢径、颈椎管率及有效颈椎管率。结果颈椎C3、C4、C5、C6、C7的椎管矢状径及椎体中矢径两组比较差异无统计学意义(P>0.05);而颈椎C4、C5、C6、C7两组的颈椎管率比较差异有统计学意义(P<0.01);颈椎C3、C5、C6有效颈椎管率两组比较差异有统计学意义(P<0.05或<0.01)。结论 X线中有效颈椎管率用于诊断退行性颈椎管狭窄有较高价值,值得临床推广。更多还原

【Abstract】 Objective To investigate value of cervical vertebra lateral X-ray in the evaluation of degenerative cervical spinal stenosis. Methods 200 healthy people including 100 men and 100 women—who underwent physical examination in the the last five years—were selected as the object of study. All of them were divided into young group( 92 cases) and middle and old aged group(108 cases) according their ages. Then,sagittal diameter of spinal canal,sagittal diameter of central vertebral body,rate of cervical spinal canal and rate of effective cervical spinal canal of cervical vertebra C3,C4,C5,C6 and C7 were calculated. Results Differences of sagittal diameter of spinal canal and sagittal diameter of central vertebral body of cervical vertebra C3,C4,C5,C6 and C7 between the two groups were not statistically significant( P > 0. 05). However,differences of rate of cervical spinal canal of cervical vertebra C4,C5,C6 and C7 in both groups were statistically significant( P < 0. 01). In addition,differences of rate of effective cervical spinal canal of cervical vertebra C3,C5 and C6 were statistically significant between groups( P < 0. 05 or 0. 01). Conclusion Effective cervical spinal canal rate of X-ray has high value for the diagnosis of degenerative cervical spinal canal stenosis. Thus,it is worthy of promotion in clinic.更多还原
