Extended Anterolateral Approach and Rim Plate Fixation for Posterolateral Fragments in Tibial Plateau Fractures

Abstract

Posterolateral fragments (PLFs) are commonly seen in tibial plateau fractures, but their reduction and fixation are challenging. There is no consensus about the ideal approach to fix this particular fragment. Even though an anterolateral approach is a safe option, it may impair a correct reduction. The posterolateral and posterior approaches offer direct visualization of the fragment, and enable a fixation with a biomechanical advantage; however, they are more demanding and expose the patient to a higher risk if morbidity. The following technical note describes the reduction and fixation of PLFs with a rim plate through an extended anterolateral approach using the paralateral collateral ligament space.
