Anterior column fixation

Similarly, the anterior part of the fracture is compressed with an appropriately placed lag screw.

The anterior screw is placed obliquely from above the greater sciatic notch across the fracture. It is aimed anteriorly towards the root of the superior pubic ramus. The entry point is along the anterior (gluteus medius) pillar of the iliac wing, 3 to 4 cm above the acetabular margin.

A 7.3 mm partially threaded screw is usually used to offer compression of the anterior portion of the transverse fracture.

A 2.8 mm guidewire is inserted along the anterior column before the appropriate length screw is passed over the wire.
