This technical paper describes infrapectineal plating — placement of an undercontoured 3.5-mm reconstruction plate below the iliopectineal line inside the true pelvis — as a surgical adjunct for acetabular fractures with medial quadrilateral surface displacement. It details surgical setup, plate contouring, fixation points, and neurovascular precautions via ilioinguinal or modified Stoppa approach.
When you encounter an acetabular fracture with medial femoral head migration and quadrilateral surface protrusion into the true pelvis — especially both-column, T-type, or anterior column/posterior hemitransverse patterns.
Consider adding an infrapectineal buttress plate as an adjunct to your standard fixation; standing contralateral and working deep to the rectus gives you the best angle on this exposure.
