Supra-pectineal quadrilateral buttress plating versus infra-pectineal plating in the management of quadrilateral plate fractures: A randomized controlled trial

Authors concluded that the anatomical QLP made it easier to reduce and fix acetabular fractures with a displaced medial wall. This was done by using multidirectional screws in the posterior column through its infra-pectineal extension and a strong screw purchase aimed at the posterior column through its supra-pectineal part. The two groups were similar in terms of final radiological and clinical outcomes, as well as residual medial wall displacement rates. However, the QLP had less morbidity than the classic infra-pectineal plating (shorter operation time and less blood loss).
