[1] Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures.

To avoid the irritation of damaged jewelry from such scratches and flaws, gold colored titanium jewelry is a safer substitute. Piercing jewelry is often made of a gold alloy , the most common being 18k, with 24k being entirely pure and much softer. 18k gold usually contains 75% gold and the remaining 25% copper , silver and traces of other metals.
When the two metal surfaces rub against one another in the joint, it can create metal ions. Some people have reactions to those ions, which can loosen the implant and cause tissue damage around ...
Joint replacements and implants are made from materials such as titanium that are not recognised by the human body (so they will not be attacked by the immune system and rejected). With an ageing population, over 50,000 hip replacements are now carried out in the United Kingdom each year.

A plug (sometimes earplug or earspool), in the context of body modification, is a short, cylindrical piece of jewelry commonly worn in larger-gauge body piercings. [1] Modern western plugs are also called flesh tunnels. Because of their size—which is often substantially thicker than a standard metal earring —plugs can be made out of almost ...
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 to the ...
