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.
