摘　　要：通过对１００例正常颈椎，自Ｃ２到Ｃ７共６００个倾角测量结果表明，倾角范围２５°～７５°，自上向下倾角均值逐渐递减，Ｃ５－７倾角均值均小于４５°，Ｃ６倾角值最小，男性倾角大于女性。在大于４５°的１７７个倾角中，位于Ｃ２－４者１５１个占８５．３％，而小于４５°的１７９个倾角中，位于Ｃ５－７者１４３个占７９．８％，颈椎病以下颈椎多见，这与下颈段倾角小有关。小倾角是颈椎病发病的潜在因素。Six hundred dip angle of intervertebral joint surface were measured in 100 cases with normal cervical spine on lateral radiograph. The results showed that the range of dip angle was 25°～75°. From C2-C7 the average value of dip angle was gradually decreased. C5-C7 was less than 45 degree. C6 was the least, and the angle in male was more large than the female. For 177 dip angle large than 45 degree,151 of them was located at C2-4 (85. 3%), but 179 dip angle less than 45 degree, 143 of them was located at C5-7.Cervical spondylosis was more fraquently visible on C4-7.Authors suggested that cervical spondylosis was related to the dip angle, and lesser dip angle was the potential pathogenic factor.
