Predicting muscle fascicule paths for use in customized biomechanical models

Patient specific biomechanical models can be applied in the design and analysis of orthopaedic implants, preoperative planning and accurate interpretation of post operative outcomes. The first step to obtain reliable customized models is by having a precise estimate of the patient specific morphology. In this study a method is presented to create patient specific models from an idealized generic musculoskeletal model. Bony morphology, wrapping structures and muscle attachment sites are derived by non-uniform scaling of a generic musculoskeletal model. This data is used as an input for a wrapping algorithm that predicts muscle fascicule paths.
