颈椎曲度变化与退变关系的生物力学分析

The article explores the relationships between cervical curvature changes and cervical degeneration to reconsider the clinical significance of cervical curvature. Lateral radiographs were taken in 240 healthy adults at the age of 21 to 80 with non symptoms. The range of individual cervical curvature was measured with Bordens method and then processed through statistics. The results showed that cervical curvature was a complicated clinical index and had much to do with age and gender. The factors for cervical curvature change varied between male and female. The accuracy of cervical curvature measurement was affected with the age growth. It is concluded that cervical curvature is an index which reflects the whole degeneration of the cervical vertebra. It has an excellent reaction to cervical functional state before the age of 60. But after that, it can only be a reference index clinically. Reconstruction of cervical curvature is considered important and necessary in the treatment of cervical spondylopathy in the young cases.
