The modified posterior MIS approach to hip resurfacing and total hip arthroplasty (hip replacement) displays a host of advantages to the patient: Less post-operative pain; Less soft tissue damage and pressure on muscle fibres. Shorter hospital stay; Lower blood loss; Smaller incision; Quicker return to work and functional activities [2]
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 ...
Approximately 58% of total hip replacements are estimated to last 25 years. [3] The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries. [4]
A variety of methods may be used to treat the disease, [5] with the most common being total hip replacement (THR). However, THRs have a number of downsides, including long recovery times and the lifespans of the hip joints (often around 20 to 30 years). [ 22 ]
The OHS is the most commonly used patient-reported hip specific measure available, because it can be completed anywhere. [ 7 ] The OHS and the Oxford Knee Score (OKS) were both adopted by the UK Department of Health for the assessment of hip and knee replacement operations carried out each year in National Health Service hospitals.
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 loosening on medical imaging.
The pelvic bone, also known as the innominate bone, is formed by three bones fused together: the ilium, ischium, and pubis. The musculature of the hip is divided into anterior hip muscles and posterior hip muscles. The major nerve supply that runs through the hip joint is the femoral nerve and the sciatic nerve. [16]
Hip resurfacing is 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 similarly to the cap of 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 ...
