Scoliosis is a spine irregular deviation, which known an idiopathic ailment among children and adolescents. Indeed, applying loads on the human spine and the capacity of the vertebral column should be tretated as random variables. The main gola of this study is to compare the maximum stress caused by weight load of a norm al and scoliosis spinal. To do so, the numerical analyses associated with the inherent random parameters of bones and applied load are performed. Accordingly, the maximum stress for all vertebrae and discs are computed. The maximum stress intensity in the cortical tissue, cancellous tissue and discs was identified. The location of the maximum stresses quantify which vertebrae and discs may get damaged and needed reinforcement and this can provide a model for predicting the location of spinal cord injury.
