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 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.
Hip fracture. A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [ 2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [ 2] Usually the person cannot walk. [ 3]
Cement in a vertebra as seen on plain Xray. Kyphoplasty is a variation of a vertebroplasty which attempts to restore the height and angle of kyphosis of a fractured vertebra (of certain types), followed by its stabilization using injected bone cement. The procedure typically includes the use of a small balloon that is inflated in the vertebral ...
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 ...
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 .
