Outcomes of Posterior Arthroscopic Reduction and Internal Fixation for Trimalleolar Ankle Fractures

Abstract

Posterior malleolar fractures (PMF) within a trimalleolar ankle fracture pattern can be challenging to manage. Due to anatomical constraints that inhibit visualization of the articular surface, reduction of the posterior malleolus relies on cortical read and/or intraoperative fluoroscopy. Posterior ankle arthroscopy is a tool that may address this shortfall by providing a means to assess the intraarticular and syndesmotic reductions, while removing any loose bodies. The purpose of this study was to determine the radiographic and patient reported outcomes of posterior arthroscopic reduction and internal fixation (PARIF) for the posterior malleolar fragment in trimalleolar ankle fractures.
