The Relevance of the Judet and Letournel Acetabular Fracture Classification System in the Modern Era: A Review

The Judet and Letournel acetabular fracture classification system, based on the idea of bicolumnar support of the acetabulum, was first described in a landmark article published in the 1960s. It has stood the test of time and continues to be the preferred method for describing acetabular fractures for the majority of orthopaedic trauma surgeons. Still, there have been attempts to modify or replace Letournel system since its introduction for a variety of reasons, chief among them a perceived inability of the classification system to account for a number of transitional fracture patterns and injury modifiers that may affect surgical decision making and patient outcomes. In this review, we present the literature related to the Judet and Letournel acetabular fracture classification system, over 50 years after its first formal description. We summarize its strengths, weaknesses, and its place in our current understanding of acetabular fractures and their recommended management.
