Abstract

Abstract: Peri-prosthetic Fractures after Total Hip Arthroplasty (THA) are a dreaded complication which happen frequently due to aging and day to day normal activities of the patient. These fractures happen below the cemented/uncemented stem, either straight/oblique direction concerning the transverse plane. Treatment requires surgical stabilization using metal plates, screws, cables and/or clamps. However, stress shielding in bone due to metal plates can be reduced by designing implants with fibre reinforced polymer composites. The present study aims to study the stress distribution in a composite plate using carbon fibre for a B1 type periprosthetic femoral fracture fixation in immediate postoperative (IPO) condition and compared with metal plate by varying geometrical parameters, laminate stacking sequence and fibre orientation. To evaluate the axial stiffness and surface stress of composite plate fixation finite element (FE) analysis was done. Various parameters like axial movement, shear movement, strain and maximum stress are considered to measure the fracture stability and the healing process through FE method. The results showed that the proposed composite bone plate could be a potential candidate for replacement of metallic bone plates for periprosthetic fracture in the femur.
