Black &Nickel Alumina Based Ceramic Femoral Head For Hip Joint

Low wear - On polyethylene acetabular cups show a more than 50% wear reduction compared with metal to polyethylene acetabular cups.

Minimal wear - Clinical experience and stimulated trials confirm that ceramic on ceramic bearing reduces wear to less than two micrometeres per year. This is due to unusual hardness of ceramics.

Beneficial wettability - Artificial Hip Joints are spherical, ball and socket bearing surfaces. Synovial fluid builds a film between the spherical head and inner cup. Beneficial wettability of ceramic surfaces allows excellent joint librication and therefore reduces friction at the joint.

Scratch resistant - Surface of a ceramic head or inlay withstands damage from surgical instruments or intra-articular foreign bodies. So called three body wear resulting from bone cement or bone particles is eliminated. Only adiamond can damage the ceramic surface. Even a damaged ceramic surface avoid expelling particles, unlike metal or polythene.

Bio compatibility - Aluminium Oxide ceramic is bio inert. Strong affinity between aluminium and oxygen makes it extremely corrosion resistant. High purity of material rules out chance of any chemical reaction.

Ceramic head are tailor made fitting to Stems of various designs and available in sizes of 28 mm, 32 mm and 36 mm in all neck lengths ie short, medium and long.
