4Anterior column: reduction

Reduction of the anterior column

The anterior column is then reduced to the reconstructed ilium.

Restore the iliac fossa concavity by correcting external rotation and medial displacement of the deeper part of the anterior column fragment.

Rotate the iliac wing internally using a ball-tip pusher applied to the proximal posterior portion, near the pelvic brim, of the anterior column and a Farabeuf clamp positioned on the ASIS.

If indicated, use a Schanz screw that is driven into the AIIS combined with lateral traction on the femur to obtain the complete reduction.
