Stress analysis of femoral bone resorption with implant
Bone is a living tissue. It continuously reproduces its structure and its growth depends partly upon the applied mechanical load. After an implant is inserted, the load equilibrium is disturbed, leading to bone resorption and the stress shielding phenomena. Aseptic loosening is the main contributor...

| description | Bone is a living tissue. It continuously reproduces its structure and its growth depends partly upon the applied mechanical load. After an implant is inserted, the load equilibrium is disturbed, leading to bone resorption and the stress shielding phenomena. Aseptic loosening is the
main contributor for hip prosthesis failure. The purpose of the study is to determine the effect of bone resorption on the stress values and hence obtain a better understanding of the behavior of the stress adaptive bone-remodeling. The bone material used for the analysis was assumed to be
isotropic and linearly elastic, and the external loads applied comprised of a femoral head load and an abductor load. A Finite element computer program for evaluating the changes in bone's density and modulus was developed. The values of stress for bone, cement mantle in medial, and
lateral positions of Total Hip Replacement (THR) are presented. The failure mechanisms of THR with bone resorption observed the implant loosening since stress is reduced. |
