The prosthetic implant used in hip replacement consists of three parts: the acetabular cup, the femoral component, and the articular interface. Options exist for different people and indications. The evidence for a number of newer devices is not very good, including: ceramic-on-ceramic bearings, modular femoral necks, and uncemented monoblock cups.
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 ...
When the two metal surfaces rub against one another in the joint, it can create metal ions. Some people have reactions to those ions, which can loosen the implant and cause tissue damage around ...
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 ...
