Treatment of Low-Energy Geriatric Acetabular Fractures With Protrusio

The intrapelvic approach is ideally suited for selected geriatric acetabular fractures with quadrilateral plate involvement. Infrapectineal plating is biomechanically advantageous to buttress the fractured quadrilateral surface. As a technical tip, plate fixation posteriorly into the sciatic buttress is reliable. However, anterior fixation is inconsistent. Usage of locking screws or cabling technique is preferable.
