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 Bordens 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.
The mechanism of manipulation and remedial value of cervical flexure was explored by bringing 110 cases with cervical spondylosis and abnormal cervical flexure into study. In the light of the relation of cervical flexure and osteophyte, the X ray films were classified into three degrees—Degree I ( balance state ); Degree II (compensation state ) and Degree III ( unbalance state ). The comparison of the cervical flexure was made to see the changes before and after the treatment, and the statistics was also made to see the correlation between degenerative cervical vertebra and improvement cervical flexure. The results showed the 90% total effective rate (99 cases) and 71.04% improved rate( 58 cases) for the cervical flexure. Among them the cases with Degree I had the best recovery. It is concluded that the abnormality of cervical flexure plays a selective action ( accelerating or decelerating) in the process of cervical spondylosis. Therefore the reconstruction of cervical flexure has a significant value in treating cervical spondylosis.
