The procedure is performed by removing the head of the femur and replacing it with a metal or composite prosthesis. The most commonly used prosthesis designs are the Austin Moore and Thompson prostheses. A composite of metal and HDPE that forms two interphases (bipolar prosthesis) can be used.
Eponymous implants and their uses. Austin-Moore prosthesis for fracture of the neck of the femur; Baksi's prosthesis for elbow replacement; Charnley prosthesis for total hip replacement; Condylar blade plate for condylar fractures of the femur; Ender's nail for fixing intertrochanteric fracture
Types of prosthesis used for replacing joints in the human body. Lower extremity prostheses are often categorized by the level of amputation or after the name of a surgeon: Transfemoral (Above-knee) Transtibial (Below-knee) Ankle disarticulation (more commonly known as Syme's amputation) Knee disarticulation; Hip disarticulation; Hemi-pelvictomy
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.
For the last 45 years, [when?] the most successful and common form of arthroplasty is the surgical replacement of arthritic or destructive or necrotic joint or joint surface with a prosthesis. [ medical citation needed ] For example, a hip joint that is affected by osteoarthritis may be replaced entirely ( total hip arthroplasty ) with a ...
Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct.
Definitions. Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". [1] An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate". [2]
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 ...
Implant (medicine) Orthopedic implants to repair fractures to the radius and ulna. Note the visible break in the ulna. (right forearm) A coronary stent — in this case a drug-eluting stent — is another common item implanted in humans. An implant is a medical device manufactured to replace a missing biological structure, support a damaged ...
Hip prosthesis zones. Zones of a hip prosthesis, by the DeLee and Charnley system, [1] and the Gruen system. [2] After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis ...
