Numerical study of the mechanical behavior of the system “bone-endoprosthesis” under different physiological loading

Abstract

Degenerative diseases of the musculoskeletal system significantly worsen the quality of people’s life. To replace only the damaged part of the hip joint hip resurfacing arthroplasty is used. For a safe selection of the prosthesis design, choosing mechanical characteristics of the implant and determination of the range of safe loads for the system “bone-endoprosthesis” it is worth to use computer simulation. This paper presents a numerical study of the mechanical behavior of the system “bone-endoprosthesis” under different physiological loads. The influence of the types of load on the stress-strain state is analyzed. The working range of physiological loads of the bone-endoprosthesis system is determined.
