Objective. To understand how height patterns (loss and gain) at AD and PD affects the PF contact loading during moderate and severe grades of cervical disc degeneration (DD).
Three numerical cases are considered for the loading responses of stratified viscoelastic earth to second degree harmonic load, uniform disc ice load, and last-glacial realistic ice load respectively.
Study Design. An in vivo rat-tail model was used to study the effects of static compression with different loading magnitudes and durations on the intervertebral disc.
