Centralizing the Cemented Exeter Femoral Stem Using the Direct Lateral Approach: Surgical Tips and Radiological Evaluation.

ABSTRACT: Varus malalignment in total hip arthroplasty has been associated with poor long-term outcomes and complications including abnormal load distribution, endosteal osteolysis, frank loosening, and periprosthetic fractures. Postoperative radiographic assessment was performed on 224 patients from our case series who underwent cemented Exeter total hip arthroplasty using the direct lateral approach alone. No patient had a true varus-aligned stem (ie, ≤-5° on the coronal assessment). We describe our surgical technique, with 4 easily reproducible technical tips to achieve positional consistency of the femoral stem: commencing stem insertion from the piriform fossa entry point, using a femoral stem distal centralizer, aiming the tip of the component to the center of the patella, and placing the thum
