Ages Eligible for Study:   72 Years and older   (Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult patients undergoing surgery for total hip replacements, including diagnosis of osteoarthritis, rheumatoid arthritis, traumatic and post-traumatic arthritis, avascular necrosis and congenital dislocation of the hip. Congenital dislocation of the hip will be included where small but anatomical acetabuli are present, ie., the acetabuli located near the tear-drop
  • Revisions of failed osteotomies may be included
  • Bone quality felt to be acceptable to the surgeon for cementless arthroplasty preoperatively in patients > 72 years of age

Exclusion Criteria:

  • Patients with active infection
  • Revision cemented total hip replacement
  • Charcot joints
  • Patients with primary or secondary bone tumors in the vicinity of the joint to be replaced
  • C.D.H. with abnormally placed acetabuli or femoral canals
  • Fibromyalgia patients
