Advances in Specialist Hip Surgery

Abstract

The acetabular cup should be optimally oriented to prevent dislocation and to reduce wear of the bearing surface after total hip arthroplasty. Several techniques such as a mechanical guide and navigation systems have been developed to achieve proper cup positioning. However, optimal cup positioning is challenging. We present a technique of acetabular cup positioning using anatomical landmarks of the acetabulum. © Springer Nature Switzerland AG 2021.
