NCT04668430

Brief Summary

Advances in biomechanical modeling of musculoskeletal systems make it possible to consider the use of a digital clone of a patient to test surgical procedure before carrying it out on the patient himself. The study aims at evaluating the design and simulation procedure of anatomical and functional pre and post surgical patient-specific numerical models.
