用冰冻连续切片、显微镜、接目测微镜观察测量14具年龄＞50岁的新鲜颈椎标本，结果显示，钩突增生占21.43％，椎动脉在横突孔内侧占57.86％，椎动脉与脊神经间距＜1mm者占97.14％，左推动脉横径男女有显著差异；横突孔内壁无增生，横突孔半孔率7．14％，99.29％的椎动脉C6横突孔上升。表明钩突后外侧的增生、推动脉在横突孔的位置、横突孔的半孔变异及椎动脉横径窄小，可影响椎动脉血流量脊神经与椎动脉间距较小，椎动脉受压同时可影响脊神经。
Fourteen fresh cervical spondylosis> 50 years of age were observed with frozen sections, microscopic observation and micromirror observation. The results showed that the uncinate hyperplasia accounted for 21.43%, the vertebral artery accounted for 57.86% inside the transverse foramen, the distance between vertebral artery and spinal nerve <1mm accounted for 97.14%, left push arteries transverse diameter of men and women were significantly different; transverse cell wall without proliferation, transverse orifice semi-porosity rate of 7.14%, 99.29% of the vertebral artery C6 transverse foramen. The results show that the lateral hyperplasia of the uncinate process promotes the location of the veins in the transverse foramen, the half-hole variation in the transverse foramen and the narrowing of the transverse diameter of the vertebral artery, which can affect the blood flow of the vertebral artery. The spacing between the spinal nerve and the vertebral artery is small, At the same time can affect the spinal nerves.
