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]
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.
Bone cement is considered a reliable anchorage material with its ease of use in clinical practice and particularly because of its proven long survival rate with cemented-in prostheses. Hip and knee registers for artificial joint replacements such as those in Sweden and Norway clearly demonstrate the advantages of cemented-in anchorage. A ...
UHMWPE has a clinical history as a biomaterial for use in hip, knee, and (since the 1980s), for spine implants. An online repository of information and review articles related to medical grade UHMWPE, known as the UHMWPE Lexicon, was started online in 2000. Joint replacement components have historically been made from "GUR" resins.
DePuy develops and markets products under the Codman, DePuy Mitek, DePuy Orthopaedics and DePuy Spine brands. DePuy Orthopaedics designs, manufactures, markets and distributes products for reconstructing damaged or diseased joints and for repairing and reconstructing traumatic skeletal injuries.
Hip replacement can be performed as a total replacement or a hemi (half) replacement. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.
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 ...
Oxinium. Oxinium is the brand name of a material used for replacement joints manufactured by the reconstructive orthopedic surgery division of medical devices company Smith & Nephew. It consists of a zirconium alloy metal substrate that transitions into a ceramic zirconium oxide outer surface.
Vitallium was developed by Albert W. Merrick for the Austenal Laboratories in 1932. Subperiosteal maxillary implant made of Vitallium 1977. In 2016 Norman Sharp, a 91-year-old British man, was recognised as having the world's oldest hip replacement implants.
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.
