Loosening of Bipolar Hip Prosthesis due to Wear of Polyuetyylene: A Case Report

Abstract

We report a case in which endosteal bone erosion was found to have developed three years after hip prosthetic surgery was performed. Radiography showed that the bone erosipn was present all around the femoral stem.
The histological speciment showed focal aggregates of macrophages and gaint cells with high density polyethylene wear debris suggestig that the development of bone erosion may occur due to the interaction between foreign bodies and macrophages.
