摘要
对１９８９年内２４５例颈椎Ｘ线片和病史资料进行分析，发现了颈椎退变的程度和范围随年龄的增加而加重。椎体前缘骨赘增生，椎间隙狭窄，钩椎关节退变是中年以后常见的退化现象。Ｃ＿（５～６）是退变发生率最高的节段。为了准确地表示椎间盘退变的程度，设计并应用了椎间隙高度指数表示法，以便对不同个体和年龄组进行比较。对于椎间盘高度的测量发现，退变过程中椎间盘前部高度的减低较后部更明显，是造成退变颈椎生理曲线异常的主要原因。
AbstractTwo hundred and forty five cases of cervicalspine degeneration were reviewed in 1989.The de-generative changes were progressive with thepatient’s age after their thirties. The formation ofanterior osteophyte,disc space narrowing and hy-pertrophy of the Luschka’s joints were most com-monly seen in this series. The C_(5-6) is the most fre-quently involved level and then follows the C_(6-7),and C_(4-5) The authors had designed the index ofthe disc space to measure the height of the discspace,so as to avoid the observational errors dueto individual variations. The narrowing of the an-terior space appeared to be faster than that seen inthe posterior space,and was an important factorof the loss of the normal curvature of the cervicalspine .
