"anterior border: runs from the anterior aspect of the head to the triangular shaft just proximal to the lateral malleolus. Distally it turns laterally to form the posterior wall of the triangle."
"posterior border: runs from the styloid process to the medial aspect of the posterior groove of the lateral malleolus."
"medial border (also known as the interosseous border): sits medial to the anterior border and descends to the rough area proximal to the talar facet."
"lateral surface: between the anterior and posterior borders. Its lower third surface faces posteriorly. Distally it is continuous with the lateral malleolus’s posterior groove."
"medial surface (sometimes called the anterior surface): between the anterior and medial borders. It faces forward and medial and is narrowed proximally."
"posterior surface: between the medial and posterior borders. Superiorly until its lower third, it is divided by the medial crest, a prominent vertical ridge. The medial posterior surface is concave. The lateral posterior surface initially faces posteriorly but ends facing medially at the lower end just above the talar facet, the rough area for attachment of the transverse tibiofibular ligament."

"The fibula runs posterolateral to the tibia and consists of a head, neck, shaft and distal malleolus."
"It is important to understand the 3-dimensional orientation of the lateral malleolus within the ankle. The lateral malleolus is longer, larger and more posterior than the medial malleolus. Hence on a true lateral radiograph of the ankle, it is posterior to the medial malleolus."
"There are three ossification centres of the fibula."
