摘　　要：目的研究颈椎椎间隙不同程度变窄与椎间孔大小变化的关系。方法计算机辅助模拟测量15具国人颈椎解剖标本的C_(4、5),C_(5、6),C_(6、7)椎间孔的面积及在椎间隙狭窄1、2、3 mm时椎间孔面积的变化。结果在椎间隙变窄1、2、3 mm时,椎间孔的面积分别减少20%～30%、30%～40%、35%～45%。结论不同程度的椎间隙变窄导致的椎间孔面积的减少在统计学上有显著性差异,椎间孔的大小直接与椎间隙的高度有关,椎间盘退变狭窄所致的椎间孔内神经根的压迫不应被忽视。Objective To investigate the relationship between the narrowing of the intervertebral disc space and the cervical foraminal areas. Methods Computer- assisted simulation of the narrowing of the C4.5, C5.6, and C6.7 intervertebral disc space was performed on 15 anatomic specimen cervical spines to measure the foraminal areas with the degree of narrowing （ 1, 2, 3 mm） of the cervical intervertebral disc space. Results Compared with normal foraminal area values, the decrease of between 20 % and 30 %, between 30 % and 40 %, between 35 % and 45 % for the foraminal areas was found when the intervertebral disc spaces were narrowed by 1, 2 and 3 mm respectively. Conclusion Statistically significant differences were found among the foraminal areas when different degrees of intervertebral disc space were narrowed. The size of the intervertebral foramen is related directly to the height of the intervertebral disc space. Compression on the nerve root in the intervertebral foramina due to the collapse of the intervertebral disc space can not be ignored.
