## Brief Summary

Treatment of acetabular fractures needs a perfect diagnosis to anticipate surgical difficulties. E. Letournel described a rare atypical both-column fracture which " introduces enormous surgical difficulties ". Its particularity is a sagittal comminution interesting the acetabular roof.

In this experience the particular fracture is probably under-diagnosed. The purpose of this study is to give the exact incidence and a precise description of these fractures to improve their surgical management.
