The analysis of 402,051 hip replacements showed that 6.2% of metal-on-metal hip implants had failed within five years, compared to 1.7% of metal-on-plastic and 2.3% of ceramic-on-ceramic hip implants. Each 1 mm (0.039 in) increase in head size of metal-on-metal hip implants was associated with a 2% increase in failure rate.
Orthopedic implant example seen with X-ray An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage . [2]
Stress shielding. 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.
The Thomas Test examines the iliopsoas, the group of muscles that connects the spine to your legs, through the pelvis; the rectus femoris, the quad muscles that run from your hip to your knee; and ...
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 ...
Nearly 6% of Americans have cognitive disabilities such as autism and dementia, which can cause difficulty concentrating or making decisions. To create accessibility for people with these ...
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 ...
Vancouver classification. The Vancouver classification is a grading system used in orthopaedics to determine management of post-operative periprosthetic femoral fractures following a hip arthroplasty. It is named for the city Vancouver, home to the University of British Columbia where the authors of the 1995 paper worked.
