Primary Outcome Measures:
  • 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 ]

Secondary Outcome Measures:
  • Revision/removals, change in HHS, SF-12 & KAS at 2 & 5 yrs [ Time Frame: 2 and 5 years ] [ Designated as safety issue: Yes ]
  • Evaluate poly insert wear rates at 5 yrs [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
  • Compare pre-op and post-op wrist DXA scans to assess progression of osteoporosis in both groups [ Time Frame: 2 and 5 years ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: Accolade TMZF Hip Stem
Accolade TMZF Hip Stem Study Device
Device: Accolade TMZF Hip Stem
Accolade TMZF Hip Stem
Device: Accolade TMZF Hip Stem
Subjects enrolled undergo total hip replacement using the Accolade TMZF hip stem device.
Other Name: Accolade TMZF Femoral Stem

Detailed Description:

An open-label, 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 BMD values. All participating centers will comply with the federal regulations regarding patient informed consent and Institutional Review Board (IRB) approval.


Ages Eligible for Study:   18 Years to 90 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patient is a candidate for a primary total hip replacement.
  2. Patient has primary diagnosis of OA.
  3. Male and non-pregnant female patients ages 18 to 90.
  4. Patient has signed an 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 scan for a BMD reading.

Exclusion Criteria:

  1. Patients with active infection within the affected hip joint.
  2. Patients requiring revision surgery of a previously implanted total hip arthroplasty or hip fusion to the affected joint.
  3. Patients who are morbidly obese, Body Mass Index (BMI) > 40.
  4. Patients who have a neuromuscular or neurosensory deficiency, which limits ability to evaluate the safety and efficacy of the device.
  5. Patients with the following diagnosed systemic diseases: Paget's disease, renal osteodystrophy, lupus erythematosus, rheumatoid arthritis, metabolic bone disease and sickle cell anemia.
  6. Patients who are immunologically suppressed or receiving chronic steroids more than 30 days. Patients receiving oral or IV steroids within one month of surgery.
  7. Patients who are prisoners.
