The finite element analysis of the shape of the femoral head prosthesis on the influence of the hip joint

摘要

Artificial femoral prosthesis replacement is a kind of technology to replace the damaged femoral head caused by femoral head necrosis, femoral neck fracture and femoral tumor in order to relieve patients' femoral head deformities, pain, and dysfunction. In this paper, by establishing the finite element analysis model of the femoral prosthesis, respectively for different shapes of ball head and acetabulum contacts finite element simulation, get the results of the stress and strain, finally, the ball head shape optimization is given.
