颈椎终板弧形高度与椎间隙后缘骨赘的相关性研究

目的：通过对颈椎病患者上下终板弧形高度、椎间隙高度与椎间隙后骨赘的影像学测量,研究其相关性及其临床应用价值。方法：收集2017年9月至2018年9月颈椎病手术108例患者的临床资料,男48例,年龄30~72岁,平均52岁,女60例,年龄37~79岁,平均54岁。其中C_2,3 6例,C_3,4 15例,C_4,5 32例,C_5,6 42例,C_6,7 13例。术前及术后摄颈椎X线片,利用PACS（Picture Archiving and Communication Systems）调阅影像,测量椎间隙的下上终板弧形高度（L₁,L₂）,椎间隙高度（L₃）及后方骨赘的宽度（L₄）。利用Spearman分析它们之间的相关性。结果：L₁与L₄对比（r=-0.34,P<0.05）,L₃与L₄对比（r=-0.36,P<0.05）,存在负相关。L₁与L₃对比（r=0.38,P<0.05）,L₂与L₃对比（r=0.48,P<0.05）,存在正相关。L₁与L₂对比（P>0.05）,L₂与L₄对比（P>0.05）,差异无统计学意义。结论：下终板弧形高度与椎间隙后缘骨赘宽度呈负相关,通过其测量可明确颈椎退变程度,对颈椎病的早期防治有指导意义。

Study on the correlation between the arc height of cervical endplate and osteophyte in posterior margin of intervertebral space

Objective: To study the correlation and clinical value of the arc height of upper and lower endplates,the height of intervertebral space and osteophyte of posterior edge of intervertebral space in patients with cervical spondylosis.Methods: A total of 108 patients with cervical spondylosis who underwent cervical spondylosis surgery from September 2017 to September 2018 were included in the study. Including 48 males with an average age of 52 years (30 to 72) and 60 females with an average age of 54 years(37 to 79). Among them,C_2,3 of 6 cases,C_3,4 of 15 cases,C_4,5 of 32 cases,C_5,6 of 42 cases,C_6,7 of 13 cases. X-ray films of cervical spine were taken before and after operation. The images were accessed by PACS (Picture Archiving and Communication Systems) system. The lower and upper endplate arc heights (L₁,L₂),intervertebral space height (L₃),and posterior osteophyte width(L₄) were measured. Spearman was used to analyze the correlation between them.Results: L₁ was negatively correlated with L₄(r=-0.34,P<0.05),L₃ was negatively correlated with L₄ (r=-0.36,P<0.05). L₁ was positively correlated with L₃(r=0.38,P<0.05),L₂ was positively correlated with L₃(r=0.48,P<0.05). There was no significant difference between L₁ and L₂(P>0.05),L₂ and L₄ (P>0.05).Conclusion: The arc height of the lower endplate is negatively correlated with the width of osteophyte in the posterior margin of the intervertebral space. The cervical degeneration degree can be determined by measuring the arc height of the lower endplate,which has guiding significance for the early prevention and treatment of cervical spondylosis.
