Patient who has diagnosis of secondary osteoarthritis, avascular necrosis and rheumatoid arthritis

You may qualify if:

  • Patient is a candidate for a primary Total Hip Arthroplasty (THA).
  • Patient who has diagnosis of secondary osteoarthritis, avascular necrosis and rheumatoid arthritis.
  • Patient whose age is 20 or over.
  • Patient who signed an Institutional Review Board (IRB)-approved, study specific Informed Patient Consent Form.
  • Patient who is willing and able to comply with postoperative scheduled evaluations.

  • Patient who is morbidly obese, defined as having a Body Mass Index (BMI) \> 40.
  • Patient who is or may be pregnant female.
  • Patient who has neuromuscular or neurosensory deficiency, which limits ability to evaluate the safety and efficacy of the device.
  • Patient with diagnosed systemic disease (i.e. Paget's disease, renal osteodystrophy), which limits ability to evaluate the safety and efficacy of the device.
