A Multicenter Approach Evaluating the Impact of Vitamin E-Blended Polyethylene in Cementless Total Hip Replacement
Since polyethylene is one of the most frequently used biomaterials as a liner in total hip arthroplasty, strong efforts have been made to improve design and material properties over the last 50 years. Antioxidants seems to be a promising alternative to further increase durability and reduce polyethylene wear in long term. As of yet, only in vitro results are available. While they are promising,...
متن کاملEarly Clinical Outcomes with a 3-D Porous Titanium Acetabular Cup
Cementless acetabular components are associated with a significant incidence of polyethylene wear and secondary osteolysis. 3-dimentional (3-D) porous coating and enhanced shell to a liner fixation are expected to reduce the polyethylene wear and to increase the longevity of an acetabular cup. The authors report the early clinical outcome with a cementless acetabular cup, Regenerex Ringloc+ (Zi...
متن کاملResults of 3,668 primary total hip replacements
BACKGROUND AND PURPOSE In a previous study based on the Finnish Arthroplasty Register, the survival of cementless stems was better than that of cemented stems in younger patients. However, the survival of cementless cups was poor due to osteolysis. In the present study, we analyzed population-based survival rates of the cemented and cementless total hip replacements in patients under the age of...
متن کاملPremature wear and osteolysis in an HA-coated, uncemented total hip arthroplasty.
The ABG I cementless hip prosthesis has demonstrated unacceptably high rates of wear and osteolysis in our patients. We performed a retrospective study of 97 hips implanted between 1992 and 1998. Radiographic analysis revealed high rates of wear of the polyethylene liner with marked peri-acetabular osteolysis. Clinical examination indicated that many of these patients were initially asymptomati...
متن کاملPoor mid-term results of total hip arthroplasty with use of a Hylamer liner.
Clinical results after total hip arthroplasty with the use of a Hylamer liner have been described as being poor. In this study, polyethylene wear rates as well as clinical results were assessed after hip arthroplasty using a Hylamer liner. Thirty patients were followed radiographically and clinically after total hip arthroplasty with a Hylamer liner. The mean follow-up was six years. Radiolucen...
