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 ...
An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures—most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint .
The Exeter hip replacement system (with a slightly different stem geometry) was developed at the same time. Since Charnley, improvements have been continuous in the design and technique of joint replacement (arthroplasty) with many contributors, including W. H. Harris, the son of R. I. Harris, whose team at Harvard pioneered uncemented ...
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often ...
Hip prosthesis displaying aseptic loosening (arrows) Hip prosthesis zones according to DeLee and Charnley, [39] and Gruen. [40] These are used to describe the location of for example areas of loosening. On radiography, it is normal to see thin radiolucent areas of less than 2 mm around hip prosthesis components, or between a cement mantle and bone.
Osteoplasty is the branch of surgery concerned with bone repair or bone grafting. It is the surgical alteration or reshaping of bone. It may be used to relieve pain associated with metastatic bone disease. [unreliable medical source?] Percutaneous osteoplasty involves the use of bone cement to reduce pain and improve mobility.
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".
The human body's own cartilage is still the best material for lining knee joints. This drives efforts to develop ways of using a person's own cells to grow, or re-grow cartilage tissue to replace missing or damaged cartilage. One cell-based replacement technique is called autologous chondrocyte implantation (ACI) or autologous chondrocyte ...
