The intervertebral disc (IVD) is often modeled as a biphasic tissue, with both a solid and a fluid phase . While under a constant compressive load, the IVD responds with continuous creep displacement, resulting in the loss of interstitial fluid from the tissue and increased strain on the annular fibers. The mechanical response of the IVD under impact loading conditions has been previously reported by the authors and others. It is unknown, however, how the loss of interstitial fluid affects disc biomechanics under impact loads. In this study, we investigate the effects of creep on IVD impact mechanics.
