Computer modeling of the structures of the musculoskeletal system

Currently, orthopedic surgeons do not have information about what loads on the bone-implant regenerate system are permissible at the stage of regeneration and do not lead to the destruction of the newly formed bone tissue. The general approach to the construction of computer models of complex structural formations of the musculoskeletal system is considered on the example of reconstruction of the ulna in a fracture, of a foot in an ankle fracture and varus deformity of the toe and pathology of the cervical spine. An approach to the construction of meaningful models has been substantiated, the possibility of a personalized approach in the construction of CT and MRI geometric computer models of biological objects in the Mimics program, which allows converting the object into the Solidworks program, has been illustrated, and the calculations of stresses, displacements and deformations in the considered models in the SolidWorks Simulation program have been performed. Since there are no studies in the available literature for all considered biological objects with implants, a comparative analysis of the calculation results was carried out for the most complex of the considered models - the cervical spine is normal. The constructed models can be used for biomechanical assessment of the state of the structures of the musculoskeletal system at different stages of reconstruction.
