There is a consensus that the biological advantages of ceramics contribute to improve the clinical outcomes and possibly do not compromise the patient s health even in association with comorbidities.
Ceramic on ceramic hip joint.
Ceramic on ceramic ceramicised material.
The extreme hardness of this type of ceramic offers greater scratch resistance than the conventional implants used in conventional hip replacements 1 ceramic on ceramic surfaces have demonstrated significantly lower wear versus conventional plastic on metal hip systems in the laboratory 2 therefore it is anticipated that these improved wear characteristics may extend the life of the implant.
Low friction good lubrication and very low wear in vitro and in vivo.
The alternative bearing couples such as metal on polyethylene and metal on metal are more inclined to wear and produce particulate debris.
Bearing affects your hip s mobility flexibility and range of motion as well as how the implant will stand up over time and how stable it will be in your body.
International registries show a growing trend in the use of ceramics in primary hip procedures.
Bearings can be made of ceramic or polyethylene medical grade plastic.
Ceramic is meanwhile the preferred femoral head material in hip replacement.
This bearing plays a particularly relevant role in young active patients and shows advantages over other bearings in biocompatibility wear rate and lubrication properties.
Frictional wear is minimized with ceramic on ceramic artificial hips.
Also the fracture risk is relatively low.
The ceramics used in hip replacement surgery are alumina ceramic and zirconia ceramic.
Ceramic on ceramic coc bearings in total hip arthroplasty tha are commonly used but concerns exist regarding ceramic fracture.
Modern manufacturing techniques and developments have increased the strength and reliability of ceramic materials.
Ceramic on ceramic hip prostheses are an increasingly popular choice for hip replacement.
This study aims to report the risk of revision for fracture of modern coc bearings and identify factors that might influence this risk using data from the national joint registry njr for england wales northern ireland and the isle of man.
This hardness provides ceramic hip replacements with an extremely smooth surface making them much less prone to wear.
In addition to this ceramic particles are biologically inert.
The use of ceramic on ceramic coc bearings in primary total hip arthroplasty tha is increasing and has been intensively analysed.
These are some of the hardest substances known with only diamond being harder than aluminum oxide ceramics.
Countries like italy germany france or korea adopted ceramics very early on however in other countries like the usa or in the uk only recent issues and concerns about fretting corrosion led surgeons to use ceramics instead of cocr heads.
Ceramic components are perceived as a reasonable choice.
