Fig. 3From: Surgical exposure to posterolateral quadrant tibial plateau fractures: an anatomic comparison of posterolateral and posteromedial approachesThe percentage of posterolateral cortical area shielded by fibular head on transverse plane (a) and coronal plane (b). On transverse plane, the percentage was more than 50% (a). Because of the fibular head, it is difficult to reduce the PL fragment and place the buttress plate via a posterolateral approach.
