Clinical and radiological outcome following total hip arthroplasty with an uncemented trabecular metal monoblock acetabular cup.
Uncemented acetabular components are associated with a significant incidence of polyethylene wear and secondary osteolysis. The new tantalum/polyethylene composite (Hedrocel) acetabular component is designed to reduce the polyethylene wear and to increase the longevity of the acetabular cups. We report our short- term clinical outcome and patient satisfaction following use of an uncemented tant...
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 کاملCup positioning in total hip arthroplasty.
The "optimal" positioning of the cup in total hip arthroplasty can improve hip function and reduce wear, impingement and dislocation. The cup position is described as the spatial relation between the hip rotation centre and the pelvis and, as the cup orientation around the rotation centre. The first parameter affects hip balance and, if not managed properly, might result in poor function and le...
متن کاملAcetabular augmentation using a second cup during revision hip arthroplasty: an unusual case report.
Acetabular wedge augmentation is a useful technique and is recommended in situations where cup revision is likely to be excessively difficult. Numerous augmentation designs that improve the stability of the hip are now available in the market. Occasionally, however, these devices are not readily available, particularly if problems such as instability and dislocation are not anticipated preopera...
متن کاملAcetabular Reconstruction in Total Hip Arthroplasty
The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. Acetabular reconstruction in revision total hip arthroplasty can successfully be achieved with hemispherical components featuring a porous or roughened ingrowth surface and options for placement of multiple screws for minor acetabular defect. Acetabular component select...
