Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. [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.
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 ...
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
A team of experts hoped a new, first of its kind, technology could help transform the future of hip replacement surgery. Researchers in Cambridge have won an award to further develop their ...
A titanium hip prosthesis, with a ceramic head and polyethylene acetabular cup. Ceramics are now commonly used in the medical fields as dental and bone implants. [8] [9] Surgical cermets are used regularly. Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response.
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 ...
Biocompatibility. Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
Osseointegration (from Latin osseus "bony" and integrare "to make whole") is the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant ("load-bearing" as defined by Albrektsson et al. in 1981). A more recent definition (by Schroeder et al.) defines osseointegration as "functional ...
