Abstract

This paper does a retrospective study of the reported cases of femur fractures and implants failure at the Accident and Emergency center, of the KATH, between 2009 and 2010. Also the paper does a comparative analysis on the bending properties of the implants received at the orthopaedic department of the accident and emergency center of the KATH. The study reveals that, the highest case of reported fractures and failure of implants is on the femur. Also most failures occurred due to early weight bearing. To ascertain the causes of failure, due to bending, the four-point bent test was done on the samples. Three out of the twenty five stainless steel plate implants, used for fixation of a femoral fracture, failed due to bending at the hospital. One out of the three different sources, where the hospital receives its implants, had the bending properties of its implants, below the others. Typically, it recorded lower modulus of elasticity and proof load.
