A stability-based model of a growing spine with adolescent idiopathic scoliosis: A combination of musculoskeletal and finite element approaches

Adolescent idiopathic scoliosis (AIS) is characterized by three-dimensional axial rotation and lateral curvature of the spine, and is the most common type of spine deformity in adolescents ranging from age 10 to 18 years [1,2]. A medical follow-up every 4 –6 months is suggested for AIS patients [3]. There have been a number of passive, i.e. devoid of muscles, finite element (FE) models developed to simulate a growing spine with AIS [4–7]. For instance, the effects of multi-axial stresses on deformation of spinal motion segments of an adolescent h ave been investigated using both energy-based and Stokes’ growth models [4].
