Combined Medial Displacement Calcaneal Osteotomy and Hintermann Osteotomy Fixed With a Single Antegrade Screw: How Do We Do It?

Progressive collapsing foot deformity stage 1AB is often managed surgically with lateral column lengthening and medial displacement calcaneal osteotomy (MDCO), among other procedures. The Hintermann osteotomy is an option for lateral column lengthening with the theoretical advantage of decreased risk of subtalar and calcaneocuboid joint degeneration relative to the Evans osteotomy. It can be easily performed in conjunction with an MDCO to amplify the mechanical effects of each osteotomy. This paper serves as a technique guide for the Hintermann osteotomy combined with the MDCO and fixed with a single antegrade screw. Level of Evidence: Diagnostic level 5.
