Avascular Necrosis of the Tibial Plafond Following Rotational Ankle Fractures

Abstract

Avascular necrosis (AVN) following rotational ankle fractures is most commonly described in the talus; however, it can also occur in the tibial plafond. These sequelae of ankle fractures are rarely described in the literature. Diagnosis of AVN is best confirmed with MRI of the involved extremity. Treatment options range from conservative treatments such as observation and limited weight-bearing to surgical management including percutaneous drilling, ankle arthrodesis, and total ankle arthroplasty. More research is needed to further identify patients at high risk for developing these sequelae of ankle fractures and to aid in the treatment and surgical decision-making process.
