Many researches point out that intervertebral pressure and
transformation are key parameters for evaluating intervertebral
disc degeneration. Aiming at avoiding the damage caused by direct and indirect
measuring methods, this research proposes a cylindroid hypothesis and measuring
method, which can monitor the strain condition of the intervertebraldisc in vivo and real-time without being
damaged.
