Acetabular Fx Classification
The Judet and Letournel classification can be confusing to apply. However, it can be simplified by breaking it down and looking at just 5 things in order:
(1) Iliac wing disruption
(2) Obuturator ring disruption
(3) Disruption of both the ilioischial line and the iliopectineal line
(4) Presence of a posterior wall fracture
(5) Complete articular separation
Approaches for how to fix these fractures are then split into anterior-based approaches and posterior-based approaches and the choice is dictated by the fracture patterns.
