These are fractures of the proximal fibula, produced by an avulsion (traction) mechanism. The pathology is similar to a rupture of the collateral ligament.
Avulsion of fibular head can indicate several ligamental injuries (besides LCL, the insertion of biceps femoris and the fibula-popliteal lig.may also be avulsed).
Avulsions of the capsular attachments are classified as AO/OTA 41A1.1 fractures.
