Alumina ceramic-on-ceramic total hip replacement with a layered acetabular component.
A modular layered acetabular component (metal-polyethylene-ceramic) was developed in Japan for use in alumina ceramic-on-ceramic total hip replacement. Between May 1999 and July 2000, we performed 35 alumina ceramic-on-ceramic total hip replacements in 30 consecutive patients, using this layered component and evaluated the clinical and radiological results over a mean follow-up of 5.8 years (5 ...
متن کاملHigh survivorship with a titanium-encased alumina ceramic bearing for total hip arthroplasty.
BACKGROUND Although ceramic-on-ceramic bearings for total hip arthroplasty (THA) show promising results in terms of bearing-surface wear, fracture of the bearing, insertional chips, and squeaking remain a concern. QUESTIONS/PURPOSES Our primary objective of this report was to determine overall survivorship of a titanium-encased ceramic-on-ceramic bearing couple. Our secondary objectives were ...
متن کاملDoes gallbladder angle affect gallstone formation?
INTRODUCTION Morphology of gallbladder varies considerably from person to person. We believe that one of the morphological variations of gallbladder is the "gallbladder angle". Gallbladder varies also in "angle", which, to the best of our knowledge, has never been investigated before. The purpose of this study was to investigate the impact of gallbladder angle on gallstone formation. METHODS ...
متن کاملRetrieval analysis of alumina ceramic-on-ceramic bearing couples
BACKGROUND AND PURPOSE Ceramic-on-ceramic (CoC) bearings have been in use in total hip replacement (THR) for more than 40 years, with excellent long-term survivorship. Although there have been several simulator studies describing the performance of these joints, there have only been a few retrieval analyses. The aim of this study was to investigate the wear patterns, the surface properties, and...
متن کاملRetrieval analysis of squeaking alumina ceramic-on-ceramic bearings.
This multicentre study analysed 12 alumina ceramic-on-ceramic components retrieved from squeaking total hip replacements after a mean of 23 months in situ (11 to 61). The rates and patterns of wear seen in these squeaking hips were compared with those seen in matched controls using retrieval data from 33 'silent' hip replacements with similar ceramic bearings. All 12 bearings showed evidence ch...
