Modified Iliac Oblique-Outlet View: A Novel Radiographic Technique for Antegrade Anterior Column Screw Placement.

Abstract

Percutaneous fixation of acetabular fractures can be challenging because of the complex anatomy of the anterior column. We have used a modified iliac oblique-outlet image view in conjunction with more traditional radiographic views to place antegrade anterior column screws. This technique does not replace the pelvic inlet but is a good alternative in the lateral decubitus position because it helps to mitigate the difficulties of obtaining the pelvic inlet radiograph in this position. The purpose of this study is to describe the radiographic technique, demonstrate proper and aberrant screw placement using Sawbones, and present a review of patients in which this technique was used in clinical practice.
