Prediction of Avascular Necrosis of the Femoral Head by Measuring Intramedullary Oxygen Tension After Femoral Neck Fracture

Abstract

We believe that this method of measuring intramedullary oxygen tension is simpler and less invasive than other currently used methods and has the possibility for intraoperatively identifying a risk group that can develop a late segmental collapse of the femoral head secondary to avascular necrosis.
