Poor results of the Freeman uncemented metal-backed acetabular component. Five-to-nine-year results.
We reviewed 120 consecutive primary total hip replacements in 109 patients in whom a Freeman uncemented metal-backed component had been used. Acetabular components were used with a Freeman neck-retaining stem in one of three configurations: cemented smooth stem, uncemented smooth stem or uncemented ridged stem. After a mean follow up of 72 months (62 to 113) there were nine cases of aseptic loo...
متن کاملMetal-on-metal hip resurfacing with an uncemented femoral component. A seven-year follow-up study.
BACKGROUND Metal-on-metal hip resurfacing with hybrid fixation has been introduced as an alternative to standard total hip arthroplasty, especially for young and active patients. There are few studies in the literature on the midterm results of cementless femoral side resurfacing. The purpose of this study was to present our seven-year clinical results of a series of twenty cementless metal-on-...
متن کاملCorrelation between inclination of the acetabular component and metal ion levels in metal-on-metal hip resurfacing replacement.
We examined the relationships between the serum levels of chromium and cobalt ions and the inclination angle of the acetabular component and the level of activity in 214 patients implanted with a metal-on-metal resurfacing hip replacement. Each patient had a single resurfacing and no other metal in their body. All serum measurements were performed at a minimum of one year after operation. The i...
متن کاملA Biomechanical Model of Acetabular Cup Deformation in Metal-on-Metal and Conventional Metal- Backed Component Designs
Introduction: Press-fit acetabular components are susceptible to deformation following implantation in an under-reamed socket, with excessive deformation of metal-on-metal (MOM) components potentially leading to increased torsional friction, component micromotion and implant loosening. The purpose of this study was to evaluate the effect of design and material considerations on induced deformat...
متن کاملCatastrophic fracture of a stable metal acetabular component.
Various modes of failure of primary and revision total hip arthroplasty have been well documented in the literature over the past 30 years. Concerns over polyethylene wear, osteolysis, and hypersensitivity reactions leading to component loosening and early revision have been evaluated and reported in the literature. Routine follow-up is important to monitor for postoperative issues that might l...
