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
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 ...
For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This procedure involves replacing both the acetabulum (hip socket) and the head and neck of the femur. The purpose of doing this surgery is to relieve pain, to restore range of motion and to improve walking ...
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
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 ...
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. [citation needed] It is the most commonly used implant for extracapsular fractures of the hip, [1] which are common ...
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 ...
Resection of pelvic bone typically requires subsequent reconstruction to ensure stability of the hip joint, particularly in internal hemipelvectomy. Examples of pelvic reconstruction include the use of an allograft, autograft, or prosthesis to bridge the remaining ends of pelvic bone following resection.
Internal fixation refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infection, which happens when implants such as plates (e.g. dynamic compression plate) are used.
