Due to the changes of modern lifestyles and the aging of the population,the incidence of spinal diseases has increased dramatically in recent years.Biomechanics research is an important part of the evaluation of spine related diseases.It is always an important means to explore the biomechanics of spine through modeling and simulation.At present,the combination of musculoskeletal model and finite element method has become a research hotspot in spinal biomechanics.Therefore,this paper investigates domestic and foreign articles that use the combination of musculoskeletal model and finite element method to explore spinal biomechanical characteristics,systematically describes the clinical application progress of this method in spine related diseases.And the paper summarizes the modeling method based on this method.It includes the setting of parameters such as loading method,Young's modulus,Poisson's ratio,and the application of this method in the evaluation of spine related diseases.The results show that based on musculoskeletal dynamics and finite element method,it provides a multi-scale evaluation method for exploring the stress,strain and IDP at the spinal tissue level during human body movement.However,this method currently has problems such as long model construction time,single research action and insufficient validation of model validity,which is the direction of future research in the field of spinal biomechanics.
