Early local microcirculation is improved after intramedullary nailing in comparison to external fixation in a porcine model with a femur fracture

Abstract

INTRODUCTION The local circulatory changes induced by intramedullary reaming are not fully understood. This study aimed to analyse the short-term local microcirculation associated with different surgical strategies in a porcine model with a mid-shaft fracture. METHODS German landrace pigs were subjected to a standardised femoral fracture under standard anaesthesia and intensive care monitoring. One group was subjected to intramedullary reaming and nailing (nail group), while a second group was stabilised with external fixation (fix ex Show more
