Medical Eponyms

Danis-Weber ankle fracture classification (Danis 1949; Weber 1972)

The Danis-Weber classification is a method of describing ankle fractures. It has three categories, based primarily upon the fracture of the fibula. The Danis-Weber classification system was first described by Robert Danis in 1949 and later modified and popularised by Bernhard Georg Weber in 1972, 10 years after Danis’ death. This simple ankle fracture classification system is more commonly called the Weber ankle fracture classification
