The Weber classification which was developed in 1972 was developed in association of the advent of the use of internal fixation. The Weber classification did not take into account the mechanics of the injury but was a simple anatomic classification according to the location of the fracture in the fibula. Nevertheless a Weber 'A' fracture is essentially caused by inversion, a Weber 'B' is an external rotation pronation fracture and a 'C' is a pure eversion injury that is also called a Dupuytrens fracture.
