Bone-cement interface of the glenoid component: stress analysis for varying cement thickness
Alexandre Terrier, Alain Farron, Philippe Büchler
BACKGROUND: Although shoulder arthroplasty is an accepted treatment for osteoarthritis, loosening of the glenoid component, which mainly occurs at the bone-cement interface, remains a major concern. Presently, the mechanical effect of the cement mantel thi ...
2005Integration of robust fluidic interconnects using metal to glass anodic bonding
This paper reports on the encapsulation of a piezoresistive silicon/Pyrex liquid flow sensor using metal to glass anodic bonding. The bonding technique allowed integrating robust metallic microfluidic interconnects and eliminating the use of glue and O-rin ...
2005Interlaminar fracture toughness improvement in composites with hyperbranched polymer modified resin
The present work aims to enhance the interlaminar toughness of carbon/epoxy composites produced by RTM by modifying the resin with hyperbranched polymers (HBPs). A HBP content of 7.5% in the resin was selected as the best compromise between a slight loss i ...
2005The interfacial transition zone (ITZ) between cement paste and aggregate in concrete
This paper describes the so called interfacial transition zone - ITZ - in concrete. This is the region of the cement paste around the aggregate particles, which is perturbed by the presence of the aggregate. Its origin lies in the packing of the cement gra ...
2004Backscattered electron imaging of cementitious microstructures: Understanding and quantification
During the last 20 years, backscattered electron imaging of polished surfaces has become well established as a method for the study of cement and concrete microstructures. The technique has many advantages, including the visualisation of representative cro ...
2004Development of vegetable fibre-mortar composites of improved durability
The primary concern for vegetable fibre reinforced mortar composites (VFRMC) is the durability of the fibres in the alkaline environment of cement. The composites may undergo a reduction in strength and toughness as a result of weakening of the fibres by a ...
2003Development and characterisation of injectable calcium phosphate cements for use in vertebroplasty
The global objective of this thesis was to understand how the starting components of brushite cements influence the cement properties relevant for its use in vertebroplasty. Therefore, this work focussed on the following cement properties : mechanical stre ...
EPFL2002The effects of calcium phosphate cement particles on osteoblast functions
Dominique Pioletti, Pascale Van Landuyt
Calcium phosphate cements (CPC) are increasingly used in the orthopedic field. This kind of cement has potential applications in bone defect replacements, osteosynthetic screw reinforcements or drug delivery. In vivo studies have demonstrated a good osteoi ...
2000The fixation of the cemented femoral component - Effects of stem stiffness, cement thickness and roughness of the cement-bone surface
Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz
After cemented total hip arthroplasty (THA) there may be failure at either the cement-stem or the cement-bone interface. This results from the occurrence of abnormally high shear and compressive stresses within the cement and excessive relative micromoveme ...
2000Quantitative Rietveld phase analysis of calcium aluminate cements
Rietveld analysis is a powerful technique for obtaining quantitative data on the relative amounts of phases in a mixture of phases, such as cement. However, a good knowledge of crystallography and the development of a refinement strategy with synthetic pha ...
