Ankle fractures - Weber and Lauge-Hansen Classification

Classification of ankle fractures is important in order to estimate the extent of the injury and the stability of the joint. The Weber classification focuses on the integrity of the fibula and the syndesmosis, which holds the ankle mortise together. The Lauge-Hansen system focuses on the trauma mechanism. Adding the stages of Lauge-Hansen to the Weber...

Special Ankle Fractures

The ankle is the most frequently injured joint. Management decisions are based on the interpretation of the AP and lateral X-rays. In this article we will focus on detection of fractures, that may not be so obvious at first sight.
