Results The prevertebral height recovery platform stage happened in all the three methods of reduction. There is no significant difference between the prevertebral heights in the maximum experimental load; the prevertebral height increased first and stayed stationary later in the hyperextension reduction procedure; in the device reduction process, the prevertebral height stayed stationary at first and dereased later.
