Modified stoppa approach for acetabular fractures with anterior and posterior column displacement: quantification of radiographic reduction and analysis of interobserver variability.

Objectives: To quantify the reduction of acetabular fractures with displacement of the anterior and posterior column by using only a single anterior approach that combines the modified Stoppa approach with the lateral window of the classic ilioinguinal approach. The second objective was to evaluate the interobserver variability of our technique for radiographic evaluation of the reduction.

Setting: Level I trauma referral center.
