Finite element analysis of the biomechanical behavior of four osseointegrated prosthetic designs.

ABSTRACT:

Objective

Osseointegration is a critical determinant of the long-term stability and functional performance of orthopedic implants, with prosthetic morphology exerting substantial influence on biomechanical loading and bone-implant interface dynamics. This study aimed to evaluate the biomechanical behavior of four representative osseointegrated prosthetic designs using finite element analysis, to inform clinical application and guide optimization in prosthetic design.

Methods

Three-dimensional finite element models were constructed to simulate host bone integrated with four distinct prosthetic configurations: (1) a threaded prosthesis representing the Osseointegrated Prostheses for the Rehabilitation of Amputees system, (2) a smooth press-fit prosthesis simulating the Osseoin
