Hip replacement. Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some ...
Hip replacement can be performed as a total replacement or a hemi (half) replacement. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.
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 loosening on medical imaging.
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 ...
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 ...
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]
[medical citation needed] For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur .
Patient procedure. A prosthesis is a functional replacement for an amputated or congenitally malformed or missing limb. Prosthetists are responsible for the prescription, design, and management of a prosthetic device. In most cases, the prosthetist begins by taking a plaster cast of the patient's affected limb.
Minimally invasive hip resurfacing (MIS) is a total or partial hip surgery that can be carried out through an incision of less than 10 cm (4 inches) without imparting great forces on the anatomy or compromising component positioning.
X-ray of a hip replacement. The modern total hip replacement was pioneered by Sir John Charnley, expert in tribology at Wrightington Hospital, in England in the 1960s. He found that joint surfaces could be replaced by implants cemented to the bone.
