Option: plate as reduction aid
An alternative or supplementary aid to reduction is a plate attached to the stable, posterior part of the ilium.
This plate is undercontoured to provide a push to the anterior column along the pelvic brim.
Place the distal part of the plate over the free anterior column fragment. Fix the plate with two cortical screws into the stable portion of the iliac wing. As its screws are tightened, the plate presses the anterior fragment into alignment with the intact ilium.
