Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis. Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, [4] certain hip fractures, benign and malignant bone tumors, [5] arthritis associated with Paget's disease, [6] ankylosing spondylitis [7] and juvenile rheumatoid arthritis. [8] The aims of the ...
The potential advantages of hip resurfacing compared to THR include less bone removal (bone preservation), a reduced chance of hip dislocation due to a relatively larger femoral head size (given that the person has an anatomically correct femoral head size), and easier revision surgery for any subsequent revision to a THR device because a ...
Artificial bone refers to bone -like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1]
This reduction in bone density ( osteopenia) is known as stress shielding and can occur as a result of a hip replacement (or other prosthesis). [citation needed] The normal stress on a bone is shielded from that bone by being placed on a prosthetic implant.
For example, a hip joint that is affected by osteoarthritis may be replaced entirely ( total hip arthroplasty) with a prosthetic hip. This procedure involves replacing both the acetabulum (hip socket) and the head and neck of the femur.
Articular cartilage repair treatment involves the repair of the surface of the articular joint 's hyaline cartilage, though these solutions do not perfectly restore the articular cartilage. These treatments have been shown to have positive results for patients who have articular cartilage damage. They can provide some measure of pain relief ...
Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. [1] [2] [3] It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so ...
Unlike in most other hip joint operations, the head of the femur is not replaced, but is allowed to heal and develop its own fibrous scar tissue so that the joint is no longer bone-to-bone, a pseudoarthrosis (also called a "false joint").
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.
The hip bone ( os coxae, innominate bone, pelvic bone [1] or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis . The two hip bones join at the pubic symphysis and together with the sacrum ...
