This thesis is concerned with the investigation, in vitro, of the mechanical properties of the intact and injured human lumbar spine under general loading conditions, by both experimentation and use of a numerical simulation. / For the experimental investigation, a three dimensional loading apparatus and displacement transducer were constructed. In order to standardize the experiment, the influence of several secondary variables was investigated. The load deflection properties of intact and injured joints were then studied. Eight states of injury were considered. As well, the effect of various types of preloading upon joint response was determined. / Using the data generated by the experimental study and measurements of the surface geometry of the vertebra, a numerical simulation was devised. This simulation allowed the interpretation of the experimental results in terms of strains in the soft tissue elements and facet interaction. As well, the locations of the instant center of rotation and the foraminal gap dimensions could be determined.
