Ceramic total hip components have been used for many years, but have undergone
fundamental changes to improve durability and fixation.
Subsequent generations have a decreased grain size, increased density, composite
materials, and a pressing process that has increased the durability and improved the
wear characteristics.Current published survivorship rates of these ceramic
components are 95%-100% at 8-10 years.
The Biolox delta ceramic head (DePuySynthes, Warsaw, IN) is promoted as ceramic head
with improved wear properties and increased stability. It is a Zirconia-toughened,
platelet-reinforced alumina ceramic. Benefits of the alumina material include a high
hardness, improved biocompatibility, and hydrothermal stability. Benefits of the
Zirconia and strontium oxide added to the alumina matrix include an increase in
fracture toughness.
The Duraloc Option Ceramic Acetabular system (DePuySynthes, Warsaw, IN) is promoted
as a system that provides excellent wear characteristics, along with proven fixation
technology. The alumina ceramic components have improved wear resistance, high
hardness, and high component reliability. These are combined with the Porocoat
porous coating composed of biocompatible titanium beads.
OXINIUM - is oxidized zirconium is a revolutionary new material that is harder and
4900 times more resistant to scratching than the common implant material
cobalt chrome . The oxinium alloy is also smoother than other metals , so there is
less friction and wear , which means you implant may last significantly longer . And
if metal allergy is a concern , these components are made from one of the most
biocompatable materials .
OXINIUM, oxidized zirconium is a metallic alloy with a ceramic surface that provides
wear resistance without brittleness. OXINIUM material combines the best of both
metal and ceramics.
OXINIUM heads on XLPE liners answer all your concerns:
- Fracture
- Metal Allergies/Sensitivity
- Osteolysis
The combination of OXINIUM heads on XLPE liners offers:
- No risk of fracture, chipping or squeaking
- Hypoallergenic Biocompatible solution for metal sensitive patients
- Proven low wear rates
In addition, OXINIUM heads and XLPE liners are available in a wide variety of head
sizes and neck offsets, which allow you the intraoperative flexibility to help
restore a full range of motion.
