This work presents an improved spine model with an articulated ribcage capable of simulating scoliosis deformities. In this model, joint constraints were defined based on experimental data. A set of clinically accepted parameters that can be measured from bi-planar radiographs, controls the spine curve and ribcage configuration of the model. The normalized compression and lateral shear forces of the intervertebral joints along the spine were reported for a normal and a scoliotic spine. Future use of the model will include investigation of the pathomechanism behind adolescent idiopathic scoliosis, simulation of brace effects, and optimization of brace treatments.
