Hot isostatic pressing. Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The process can be used to produce waste form classes. Calcined radioactive waste (waste with additives) is ...
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 socket), replacing the articulating surfaces of the ...
Material selection. Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of candidate ...
D019644. MedlinePlus. 002975. [edit on Wikidata] 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.
Biocompatibility: Ability to be in contact with a living system without producing an adverse effect. [] Biocompatibility is related to the behavior of biomaterials in various contexts. The term refers to the ability of a material to perform with an appropriate host response in a specific situation. [2] The ambiguity of the term reflects 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]
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often ...
DePuy identified reasons for the failure of the hip replacement system as component loosening, component malalignment, infection, fracture of the bone, dislocation, metal sensitivity and pain. Additional complications from the hip replacement system may include increased metal ion levels in the blood, bone staining, necrosis , swelling , nerve ...
