通过对50例颈椎骨标本的测量,统计了骨质增生的出现率和颈椎各径、钩突各径值及上关节突关节面的角度,比较了正常组与骨质增生组的差异,以阐述骨质增生对颈椎椎管、椎间管的影响,通过对钩突前后径与椎上切迹的相关统计,发现二者呈负相关。随着钩突前后径的增大,椎间管变窄。 Through the measurement of 50 cases of cervical vertebra, the incidence of osteoarthritis and the diameter of cervical vertebra, the diameter of uncinate process and the angle of the upper articular facet were counted. The differences between normal group and osteoarthritis group were compared The effects of bone hyperplasia on cervical vertebral canal and intervertebral canal were described. According to the statistics about the anteroposterior diameter and the vertebral notch of the uncinate process, they were found to be negatively correlated. As the uncinate process increases, the intervertebral canal becomes narrower.
