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.
Hot isostatic pressing. Isostatically pressed nickel alloys. 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.
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.
Artificial bones made of metal and ceramic tend to do poorly in terms of biocompatibility since it is difficult to blend into bone tissues. [4] Thus, to better help those in need to live a more comfortable life, engineers have been developing new techniques to produce and design better artificial bone structure and material.
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] The biodegradable metals in this category are magnesium-based [3] and iron-based alloys, though ...
The materials used for the replacement hip joints were usually metals such as titanium, with the hip socket usually lined with plastic. The multiaxial ball was tough metal ball but was eventually replaced with a longer-lasting ceramic ball.
