Smart mechanical navigation: Assuring cup positioning

Total hip arthroplasty has become a very successful procedure with excellent survivorship and outcomes. Despite significant advances, instability and wear continue to be problems and leading reasons for revisions of total hip replacements. We examine the application of the HipSextant mechanical navigation device and its role in reducing cup malposition, an underlying reason for hip instability and wear. A review of its results shows increased accuracy compared to conventional alignment and computer-assisted navigational methods. With its patient-specific approach, the HipSextant system is a reliable and efficient tool to achieve accurate acetabular cup placement.
