Posteromedial Surgical Approach for Fixation of Haraguchi Type 2B Posterior Malleolar Fracture.

Abstract

A case of a 26-year-old man with a displaced medial malleolus fracture with extension into the posteromedial aspect of the posterior malleolus is presented. A CT scan of the ankle is obtained demonstrating a Haraguchi type 2B posterior malleolus fracture with a posteromedial and posterolateral fragment. The posteromedial fragment extends into the posterior colliculus of the medial malleolus and has a subchondral impaction fracture. There is also a 1 × 1 cm piece of the articular surface of the posterior malleolus that has flipped 90 degrees and lodged itself between the posterolateral fracture fragment. This video overview and case presentation demonstrates a posteromedial approach with fixation strategy for the posterior malleolus.
