Statistical evaluation of the loosening of total hip replacement.
This presentation is a call for partners participating in a European Implant Data Retrieval and Analysis System of Total Hip Replacements. The aim of the proposal is the development, i.e., hardware, software components and networks services, and the centralization of a European Implant Data Retrieval and Analysis System with special references to Total Hip Replacements. The system should be eas...
متن کاملReconstruction of the Acetabulum in Developmental Dysplasia of the Hip in Total Hip Replacement
Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...
متن کاملLoosening of the femoral component after total hip replacement. The thin black line and the sinking hip.
Review of the radiographs of 882 consecutive metal-to-polyethylene hip replacements after a mean follow-up of 6.8 years showed 72 cases (8%) of aseptic femoral loosening, all of which showed a lucent zone or black line between metal and cement. In 97% of the series this appeared within two years of the arthroplasty. Progress of loosening was unpredictable and only 24% had significant symptoms. ...
متن کاملExpression of tenascin-C in aseptic loosening of total hip replacement.
OBJECTIVE To assess if the bonding interlayer between the implant and bone in aseptic loosening of total hip replacement (THR) is qualitatively deteriorated by excessive accumulation of anti-adhesive glycoprotein, tenascin-C. METHODS Alkaline phosphatase-anti-alkaline phosphatase (APAAP) method was used for immunohistochemical staining of tenascin-C in interface tissue and control synovial ti...
متن کاملImbalance of RANKL/RANK/OPG system in interface tissue in loosening of total hip replacement.
In the differentiation of osteoclasts the differentiation factor (RANKL) interacts with the receptor activator of NF-kappaB (RANK) in a direct cell-to-cell contact between osteoblast and (pre)osteoclast. This is inhibited by soluble osteoprotegerin (OPG). The mRNA levels of both RANKL (p < 0.01) and RANK (p < 0.05) were high in peri-implant tissue and RANKL+ and RANK+ cells were found in such t...
