Anatomic Fixation of Supination External Rotation Type IV Equivalent Ankle Fractures.

Objectives: To compare radiographic and clinical outcomes of supination external rotation type IV equivalent (SER IV E) ankle fractures (AO/OTA classification 44-B2.1) treated with transsyndesmotic screw fixation with those treated with deltoid and posterior inferior tibiofibular ligament (PITFL) repair.

Design: Case series and single-surgeon retrospective analysis of a prospective database.
