Classification of the hip.

Abstract

A number of classification systems have been proposed for periprosthetic fractures of the femur following total hip replacement. Most of these rely purely on the site and pattern of the fracture. However, it is only after consideration of other important factors, including the stability of the prosthesis as well as the quality of the surrounding bone stock, that appropriate management can be instituted. The authors have developed a new classification system that addresses these other important factors. The authors believe that only after classifying a periprosthetic fracture with specific reference to fracture site, stability of the implant, and quality of the surrounding bone stock, can one make a rational decision towards a treatment algorithm.
