Improved Ceramic Hip Devices

The type of ceramic used in total hip replacement today is aluminum oxide also known as alumina.

Improved ceramic hip devices.

There have been numerous studies released that tout the lack of issues within all ceramic hip replacement devices. The clinical use of ceramic as a bearing surface dates back to the early 1970s. Ceramic on ceramic seems to be the golden child for hip replacement devices for the fast few years. Metal on metal mom these are what they sound like.

Both the socket and the ball are made of stainless steel titanium chromium cobalt or some combination of these. Ionguard treated titanium hip components release 35 times less metal than untreated parts after 1 million wear cycles. The many different materials used in hip replacement devices. New hip resurfacing implant could lead to better outcomes for patients 2018 hip resurfacing at surface hippy posted on january 15 2018 by patricia walter april 22 2018.

The fda has reclassified the hip joint metal ceramic polymer semi constrained cemented or non cemented prosthesis referred to in this document as ceramic ball hip system from class iii. Deciding on a hip replacement can be a challenging and confusing process. H1 hip resurfacing implant is made of ceramic on ceramic and is strong low wearing and non toxic. Over recent years patients receiving hip implants consisting of a metal on metal ball and socket complained of problems including hip implant loosening and unexplained hip pain.

Adding to the uncertainty is the fact that a growing number of artificial hip retailers have faced lawsuits over the production of defective implants in recent years. Advanced bioceramics have played integral roles in treatment modalities for damaged or diseased human joints and osseous defects. Surgical outcomes can vary from person to person as can recovery times and lasting effects. Previously hip replacements approved by the fda used different combinations of ceramic metal and polyethylene a form of plastic.

In 1995 an improved alumina ceramic was developed that had increased purity and strength over the first generation materials. Many surgeons today consider them to be an improvement over traditional metal and plastic implants in which the deterioration of plastic can lead to the gradual buildup of debris. Ionguard treated titanium knees show wear properties comparable to co cr devices in a 3 million cycle wear study. They do not have any biological adverse effects or allergic responses for example.

Ionguard treated co cr heads remain up to 29 smoother than untreated heads in clinical usage.
