Periprosthetic Comminuted High Energy Fracture of The Proximal Femur Three Months After Primary Total Hip Arthroplasty in Young Male. A Case Report

Abstract

A 40 years old male patient had surgery on his right hip in 2010. when primary total cementless hip prosthesis was implanted because of posttraumatic arthrosis. Three months later he had a car accident and he got dislocation of the hip prosthesis with multiple femoral fractures of the proximal part of the femur around and below the femoral stem. The stem of the prosthesis was loose while acetaulum was stable. The patient had also fracture of the left acetabulum and ishial bone, without big dislocations. He underwent a new surgery on the right hip. Revisional long uncemented femoral stem was implanted, with cerclages and screws on multiple bone fragments. We met patient 8 years later with a very good function of his right hip. He has a problem with his left hip because of pseudarthrosis of the upper and lower part of the ischial bone. We think that this is an interesting case of periprosthetic femoral fracture, because of so many bone fragments around and below the femoral stem of the hip prosthesis, resulting in a very good function.
