Combined Percentage (%) Cases Without Aseptic Loosening, Intraoperative Femoral Fracture or Thigh Pain [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
The combined success rates for aseptic loosening, intra-operative femoral fracture and thigh pain is no worse for patients with osteoporotic bone than for patients with non-osteoporotic bone [ Time Frame: 2 and 5 years ] [ Designated as safety issue: Yes ]

Accolade® TMZF® Hip Stem Outcomes Study
Accolade® TMZF® Study A Prospective, Post-market, Non-randomized, Multi-center Evaluation of the Accolade® TMZF® Hip Stem

The purpose of this study is to evaluate clinical and radiographic outcome data in patients implanted with the Accolade® TMZF® femoral stem.

A prospective, post-market, multi-centered clinical evaluation of the Accolade® TMZF® hip stem device. All patients enrolled will receive the study device. All study patients will undergo a preoperative central Dual energy X-ray absorptiometry (DXA) scan to determine bone mineral density (BMD) values.

Inclusion Criteria:

  1. Patient is a candidate for a primary total hip replacement.
  2. Patient has primary diagnosis of osteoarthritis (OA).
  3. Male and non-pregnant female patients ages 18 to 90.
  4. Patient has signed an Institutional Review Board (IRB) approved, study specific Informed Patient Consent Form.
  5. Patient willing and able to comply with postoperative scheduled clinical and radiographic evaluations and rehabilitation.
  6. Patient capable of undergoing a pre-op central DXA (dual-energy x-ray absorptiometry) scan for a bone mineral density (BMD) reading.

Exclusion Criteria:

  1. Patient has an active infection within the affected hip joint.
  2. Patient requires a revision surgery of a previously implanted total hip arthroplasty or hip fusion to the affected joint.
  3. Patient who is morbidly obese, Body Mass Index (BMI) > 40.
  4. Patient has a neuromuscular or neurosensory deficiency, which limits ability to evaluate the safety and efficacy of the device.
