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.
An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. 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]
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.
The hip resurfacing devices are metal-on-metal articulating devices which differ from total hip replacement devices because they are more bone conserving and retain the natural geometry (so-called large ball THR devices share this trait).
Bone cements have been used very successfully to anchor artificial joints (hip joints, knee joints, shoulder and elbow joints) for more than half a century. Artificial joints (referred to as prostheses) are anchored with bone cement. The bone cement fills the free space between the prosthesis and the bone and plays the important role of an ...
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 ...
The 2010 DePuy Hip Recall was issued after research released by the National Joint Registry (NJR) found high rates of hip replacement failure for the ASR XL Acetabular and ASR Hip Resurfacing systems.
They have the advantage of being inert in the human body, and their hardness and resistance to abrasion makes them useful for bones and teeth replacement. Some ceramics also have excellent resistance to friction, making them useful as replacement materials for malfunctioning joints. Properties such as appearance and electrical insulation are ...
Arthroplasty. Specialty. orthopedics. MeSH. D019643. [ edit on Wikidata] Arthroplasty (literally " [re-]forming of joint ") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure.
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. The ceramic surface is extremely abrasion resistant compared ...
