Medial Column Support in Pilon Fractures Using Percutaneous Intramedullary Large Fragment Fixation.

Abstract

Pilon fractures are complex injuries to the tibial plafond requiring stable fixation in the setting of effective soft tissue management, particularly in high-energy injuries, open fractures, or in geriatric individuals. Medial column support of the distal tibial metaphysis is often an essential component when applying balanced fixation. However, the biologic implications of multiple surgical approaches in the setting of damaged tissue, devitalized bone, or significant bone loss may contribute to increased complications. Percutaneous intramedullary large fragment screws offer both stability and a soft tissue-friendly approach for stabilizing the medial column. Here, we present our technique and indications for medial column support in pilon fractures using percutaneous large fragment fixation, along with our early clinical experience in a case series of 7 patients. At minimum 6-month follow-up, all patients healed their injuries with maintained alignment and without complications or further reoperation. Medial column support with percutaneous large fragment fixation in pilon fractures is a viable option to provide mechanical stability while effectively managing tenuous soft tissue envelopes.
