The purpose of this research is to gather clinical and radiographic (X-ray) information about EMPHASYS™ acetabular shell (also called a hip 'cup') placement in total hip replacement surgery using a non-invasive surgical navigation system called VELYS™ hip navigation system with CUPTIMIZE™ Advanced Hip-Spine Analysis software.
Data collected in this study will be compared with data collected from implantations using different cup positioning instrumentation and techniques to assess performance.
All hip replacement component devices are to be used according to the approved indications.
The subject is undergoing a standard of care primary uncemented hip replacement with the EMPHASYS cup and a CORAIL, EMPHASYS or ACTIS stem via the posterolateral, anterolateral, or direct lateral approach with the subject in the lateral decubitus position.
The subject is a candidate for implantation utilizing the VELYS Hip Navigation system with CUPTIMIZE advanced
