The Deep Layer of the Tractus Iliotibialis and Its Relevance when Using the Direct Anterior Approach in Total Hip Arthroplasty: a Cadaver Study

Surgical approaches through smaller incisions reveal less of the underlying anatomy, and therefore, detailed knowledge of the local anatomy and its variations is important in minimally invasive surgery. The aim of this study was to determine the location, extension, and histomorphology of the deep layer of the iliotibial band during minimally invasive hip surgery using the direct anterior approach (DAA).
