The human spine is a geometrically, non-linear complex structure. Solid models are widely used in spine modelling studies. There is a need for developing a generic parametric spine model to be employed in biomechanical modelling of the spine to reduce the complexity of the dimensions and orientations. In this proposed parametric model, the geometric complexity of the vertebrae is simplified by associating the geometry of the significant anatomic properties of the spine. This is achieved by identifying and employing the key parameters of geometric components. The features of each vertebra are generated by using these key parameters. These features are then combined to generate the model of a particular vertebra. The variables of this generic vertebra can then be edited to model the whole spinal column. The proposed technique helps the potential user to edit the variables with less effort, in order to form a realistic model of the full spine to represent different groups of people with different dimensions and postures.
