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 fractures.
Most hip fractures are treated surgically by implanting a prosthesis. Surgical treatment outweighs the risks of nonsurgical treatment which requires extensive bedrest. [5] Prolonged immobilization increases risk of thromboembolism, pneumonia, deconditioning, and decubitus ulcers.
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.
Amputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems.
A surgeon places a bone graft into position during a limb salvage. Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk ...

A traumatic dislocation of the tibiotarsal joint of the ankle with distal fibular fracture. Open arrow marks the tibia and the closed arrow marks the talus. A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. [1] A partial dislocation is referred to as a subluxation.
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 ...
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 ...
Stress shielding is the reduction in bone density ( osteopenia) as a result of removal of typical stress from the bone by an implant (for instance, the femoral component of a hip prosthesis ). [1] This is because by Wolff's law, [2] bone in a healthy person or animal remodels in response to the loads it is placed under.
