Acetabular revision in total hip replacement with a press-fit cup.
The need for supplementary screw fixation in acetabular revisions is still widely debated. We carried out 439 acetabular revisions over an eight-year period. In 171 hips with contained or small segmental defects, the Morscher press-fit cup was used. These revisions were followed prospectively. No screws were used for additional fixation. A total of 123 hips with a mean follow-up of 7.4 years (5...
متن کاملNavigated Acetabular Cup Fixation for Acetabular Deformity or Revision Total Hip Arthroplasty
PURPOSE To evaluate the usefulness of navigated acetabular cup fixation for total hip arthroplasty in patients with acetabular deformity or revision total hip arthroplasty. MATERIALS AND METHODS This study enrolled 28 patients with at least 12 months' follow-up. The safe zone of the acetabular cup was defined as 40°±10°in inclination and 15°±10°in anteversion. The authors used the navigation ...
متن کاملPress-fit acetabular cup fixation: principles and testing.
Pre-clinical testing of the fixation of press-fit acetabular components of total hip prostheses relies on cadaver or synthetic bone, but the properties and geometry of bone models differ from those of physiological bone. Cup designs use varied mechanisms for initial stability in bone; therefore, using different analogues and tests is appropriate. Press-fit cup stability was tested in the follow...
متن کاملAcetabular Cup Revision
The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an importa...
متن کاملUsing acetabular fossa as a guide for anticipated inclination of uncemented cup in total hip replacement.
Positions of acetabular implant generally are considered to be major causative factors of dislocation. Accurate and consistent achievement of the preoperatively anticipated orientation of the acetabular cup is a great challenge in total hip replacement (THR). In the present study, we investigated the surgical application of acetabular fossa as a guide for anticipated inclination of uncemented c...
