A modular ceramic femoral head was selected for use as the bearing on a novel carbon fibre reinforced plastic (CFRP) total hip replacement femoral stem. Mechanical testing was required to validate this novel combination of materials for load bearing implant application. The Ceramic Head-CFRP Stem ...
Perspective on a 20-year experience with ceramic-on-ceramic articulation in total hip replacement Biomaterials, whatever their applications: cardiovascular surgery, orthopaedic surgery, ophthalmology, plastic surgery, urology, membranes for renal dialysis have some common approach. It is a very ...
The characteristic of atomic arrangement in ceramic structure leads to the lack of plastic deformation like ability in metal. When broken, ceramic has no other energy absorption mechanisms, except to form new broken surfaces [67]. Usually, the toughening mechanisms involve dispersion toughening, microc...

Strengthening the ceramic ball of a hip prosthesis by ion beam implantation to induce controlled bilateral compressive stress on the load-bearing surface and not make the ceramic amorphous; coating with a diamond-like-coating of bonding, amorphous, crosslinked carbon network; durability; noncracking ...
Due to their specific electronic bonding, ceramics tend to fracture rather than undergo plastic deformation. Consequently, they typically have low tensile strength, material toughness, and poor machinability [145]. More research is required to advance CMCs. Researchers must focus on low-cost mass ...
Cementless total hip replacement: Bio-active glass ceramic coating studied in dogs , the detaching load and bone ingrowth of the AW glass-ceramic-coated femoral and acetabular components were higher than those of the control implants. ... K Ido,Y Matsuda,T Yamamuro,... - 《Acta Orthopaedica》...
The response in zirconia ceramics to indentation and scratch damage is strongly dependent on grain size and additive phases, ranging from relatively brittle (fine-grain 3Y-TZP), quasiplastic (coarse-grain 9 Mg-pSZ), to plastic (intermediate-grain 12Ce-TZP) at high loads [202]. Because of ...
