This report concerns the manner in which the intervertebral disc and the posterior elements share loads placed on a lumbar motion segment. A two-dimensional biomechanical model was used to examine this. The model incorporated two rigid bodies to represent the vertebrae and six elastic springs to represent the tissues of the intervertebral disc and the posterior elements. Compression loads were resisted almost totally by the model intervertebral disc, but both the intervertebral disc and the… CONTINUE READING
