What is Biolox Delta?
BIOLOX delta is an aluminum oxide matrix composite ceramic consisting of approx. 75% alumina (Al2O3 ), 24% zirconia (ZrO2 ) and other trace elements. The pink color is due to the chromium oxide (Cr2O3 ) that increases the hardness of the composite material.
What is Biolox made of?
BIOLOX®forte is made of ultra-pure alumina (Al2O3). Alumina’s excellent compatibility with living tissues has been shown scientifically and in in-vitro and in-vivo animal studies. BIOLOX®forte alumina hip implants have been and still are successfully used for orthopedic applications since their introduction in 1994.
Why is Biolox Delta pink?
What makes BIOLOX®delta ceramic pink? Chromia is completely dissolved in the alumina matrix and gives BIOLOX®delta its characteristic pink color.
What is Biolox?
Biolox® Delta is an alumina ceramic composite that is mainly optimized with nano-sized, yttria-stabilized tetragonal zirconia and strontium oxide [2]. The transformation of the zircona phase into the alumina ceramic matrix limits the development of potential cracks [3].
What is Stryker Accolade 2 made of?
A portion of the stem is covered in a proprietary version of a calcium compound called hydroxylapatite (HA). Stryker calls its version of the material PureFix HA. The Accolade II is a similar stem that uses a metamorphic wedge designed to fit a range of bone sizes.
How long does a ceramic hip last?
How long does a ceramic hip last? On average, hip replacements last 20 to 25 years before repair or replacement. In one study , only 4.4 percent of people who received a hip replacement required revision surgery in the first 10 years after surgery. About 15 percent required revision by the 20-year mark.
What is oxinium made of?
Oxinium™ is produced by heating zirconium alloy (97.5% zirconium + 2.5% niobium) in air. The outer 5µm of the head is oxidised to form the hard zirconium oxide.
What is the best material to use for hip replacement?
Polyethylene—Plastic is by far the most common material used for hip replacement liners. This material has provided good to excellent results when paired with ceramic or cobalt-chromium balls.
What is a Stryker hip replacement made of?
It’s made from polyethylene, a type of plastic designed to increase range of motion, improve joint stability and reduce the risk of wear. Stryker also sells numerous femoral components, including press-fit stems, cemented stems and revision components.
Can ceramic hips break?
Ceramic is very smooth but sometimes creates problems when used as a hip joint replacement. Ceramic is weak and brittle compared to metal. The early ceramic implants were prone to fracture. With better materials, there are fewer fractures now–only one in 10,000, compared to one in 2,000 early on.
What are ceramic hips made of?
Among the ceramics, alumina is probably the most commonly used material. The alumina used for hip replacements was different from the first generation of the material used for industrial applications.
What is biolox® Delta?
This material also provides a new ‘option’ for using a ceramic femoral head in a revision scenario with the BIOLOX ®OPTION. Science Behind the Material. BIOLOX ® delta. Aluminum oxide matrix consisting of approximately 80% alumina, 17% zirconia and 3% strontium oxide.
What is the toughening mechanism in biolox delta material?
The first toughening mechanism used in BIOLOX delta Material results from the introduction of small, homogeneously distributed yttria-stabilized tetragonal zirconia particles (Y-TZP) in a stable alumina matrix.
What is biolox® option?
This material also provides a new ‘option’ for using a ceramic femoral head in a revision scenario with the BIOLOX ® OPTION. Aluminum oxide matrix consisting of approximately 80% alumina, 17% zirconia and 3% strontium oxide. Zirconia was added to increase the material strength and prevent the initiation and propagation of cracks.
Can biolox®duo be combined with a Delta femoral head?
BIOLOX®DUO can be combined with a BIOLOX® delta femoral head. Implant manufacturers offer this option to surgeons looking for a bone-sparing solution suitable for younger, more active patients and for patients with a sensitivity to metal.
