A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely.
Eponymous implants and their uses Austin-Moore prosthesis for fracture of the neck of the femur [13] Baksi's prosthesis for elbow replacement [14] Charnley prosthesis for total hip replacement [15] Condylar blade plate for condylar fractures of the femur [16] Ender's nail for fixing intertrochanteric fracture [17]
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.
Hip resurfacing, sometimes called hip shaving, is preferred over a total hip replacement for elite athletes, Su said, because it preserves more of the femur, uses a metal alloy made of cobalt and ...
In recent decades, the most successful and common form of arthroplasty is the surgical replacement of a joint or joint surface with a prosthesis. For example, a hip joint that is affected by osteoarthritis may be replaced entirely ( total hip arthroplasty) with a prosthetic hip.
But hip replacement surgery isn't limited to those with hip dysplasia. In general, Hooper says, "it might be time to consider a consultation for hip replacement surgery if you have severe hip ...
Co-Cr alloys are most commonly used to make artificial joints including knee and hip joints due to high wear-resistance and biocompatibility. [4] Co-Cr alloys tend to be corrosion resistant, which reduces complication with the surrounding tissues when implanted, and chemically inert that they minimize the possibility of irritation, allergic ...
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 ...
Bone cement. 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 ...
Lower-extremity prostheses provide replacements at varying levels of amputation. These include hip disarticulation, transfemoral prosthesis, knee disarticulation, transtibial prosthesis, Syme's amputation, foot, partial foot, and toe.
