Abstract :
A 3-D finite element model has been developed and is being used to analyse the effect of alteration in the nucleus fluid content on the overall mechanics of a lumbar motion segment. The results show that a change in the nucleus volume directly affected the intradiscal pressure. Similar results are also obtained in an experimental study where intradiscal pressures are measured by infusing a small volume of saline solution in an intervertebral disc in a slow and continuous fashion by a pump
