How resources affect management of periprosthetic fractures of the distal femur: perspectives from Israel, South Sudan, and South Africa

Abstract

Summary: Periprosthetic fractures of the distal femur have significant morbidity in both total hip and total knee arthroplasty (THA and TKA, respectively). The incidence of these fractures is growing, with the predominant mechanism of injury being a fall from a standing height and therefore considered fragility fractures. In many countries, improved public funding and a flourishing private health care sector, when coupled with increased life expectancy, translates to more older patients receiving both TKA and THA and therefore an increased prevalence of periprosthetic fractures and their associated complications. These fractures may occur below a long stem THA, above a TKA, or between the two (so-called “interprosthetic fracture”). We will outline fracture classification, risk factors, diagnosis, and treatment options, highlighting perspectives on treating these fractures in Israel, South Africa, and South Sudan. These countries represent differing access to resources, varied comorbidity factors, and differing health care systems. The points of difference and the points of similarity will be considered.
