Examples of prostheses from the 1990s: Examples, some of which were developed at the Redhill Group of Hospitals and Dorking Hospital, include a ringed titanium hip prosthesis with a screw stem and porous cup, a modular hip prosthesis with a textured femoral stem to aid bone grafting (material unspecified), two Thompson-type prostheses made of ...
Materials. Some ceramic materials commonly used in joint replacement are alumina (Al 2 O 3), zirconia (ZrO 2), silica (SiO 2), hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2), titanium nitride (TiN), silicon nitride (Si 3 N 4). A combination of titanium and titanium carbide is a very hard ceramic material often used in components of arthroplasties due ...
Titanium is used from head to toe in biomedical implants. One can find titanium in neurosurgery, bone conduction hearing aids, false eye implants, spinal fusion cages, pacemakers, toe implants, and shoulder/elbow/hip/knee replacements along with many more.
Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum ( pelvis ...
Hip resurfacing, sometimes called hip shaving, is preferred over a total hip replacement for elite athletes, Su said, because it preserves more of the femur, uses a metal alloy made of cobalt and ...
While osseointegration has been observed using different materials, it is most often used to describe the reaction of bone tissues to titanium, or titanium coated with calcium phosphate derivatives. It was previously thought that titanium implants were retained in bone through the action of mechanical stabilization or interfacial bonding.
