EMPHASYS Cup Positioning in THA With Non-Invasive Navigation (Velys Hip Navigation (VHN))

Purpose

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.

Exclusion Criteria

  1. Active local or systemic infection. 2. Loss of musculature, neuromuscular compromise or vascular deficiency in the affected limb rendering the procedure unjustified. 3.

Contralateral hip was replaced less than 6 months prior to surgery date. 10. Subject is currently involved in any personal injury litigation, medical-legal or worker's compensation claims. 11. Subject was diagnosed and is taking prescription medications to treat a muscular disorder that limits mobility due to severe stiffness and pain such as fibromyalgia or polymyalgia. 12. Subject has a medical condition with less than 2 years of life expectancy. 13.
