Scientific career. Fields. Orthopaedic surgeon. Sir John Charnley, CBE, FRS [1] (29 August 1911 – 5 August 1982) was an English orthopaedic surgeon. He pioneered the hip replacement operation, [4] which is now one of the most common operations both in the UK and elsewhere in the world, and created the "Wrightington centre for hip surgery".
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 ...
Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries.
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 ...
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 ...
Hip arthroscopy. Intraoperative fluoroscopic image during an arthroscopic resection of a cam lesion of the femur. The upper instrument is the arthroscope (viewing device), while the lower is the high-speed burr used for reshaping the bone. Hip arthroscopy refers to the viewing of the interior of the acetabulofemoral (hip) joint through an ...
Hip dislocations can also occur following a hip replacement or from a developmental abnormality known as hip dysplasia. Hip dislocations are classified by fracture association and by the positioning of the dislocated femoral head. A posteriorly positioned head is the most common dislocation type.
Spinal fusion was one of the five most common OR procedures performed in every age group except infants younger than 1 year and adults 85 years and older. Laminectomy was common among adults aged 18–84 years. Knee arthroplasty and hip replacement were in the top five OR procedures for adults aged 45 years and older.
DePuy identified reasons for the failure of the hip replacement system as component loosening, component malalignment, infection, fracture of the bone, dislocation, metal sensitivity and pain. Additional complications from the hip replacement system may include increased metal ion levels in the blood, bone staining, necrosis, swelling, nerve ...
An osteotomy is a surgical operation whereby a bone is cut to shorten or lengthen it or to change its alignment. It is sometimes performed to correct a hallux valgus, or to straighten a bone that has healed crookedly following a fracture. It is also used to correct a coxa vara, genu valgum, and genu varum. The operation is done under a general ...
