  • Summary of HA/Bone equivalent suppliers

    Dear list members,

    Many thanks to all those who responded to my request for information on
    suppliers of bone equivalent or hydroxyapatite materials. Below is a
    summary of the company names and contact details that were forwarded to
    me;

    Plasma Biotal Ltd
    http://www.plasma-biotal.com

    Computerized Imaging Reference Systems, Inc
    http://www.cirsinc.com

    Berkley Advanced Biomaterials, Inc
    http://www.hydroxyapatite.com

    Gammex RMI
    http://www.gammex.com

    Interpore Cross International
    http://www.interpore.com

    I have contacted a number of the companies for further details. Plasma
    Biotal Ltd have been very helpful in discussions about creating custom
    products.

    Also many thanks to Professor Liz Tanner for information about
    hydroxyapatite composites;

    "... we have a hydroxyapatite polyethylene composite with 40vol% HA but
    the mechanical properties are below those of real bone, but the
    biological response to the material is good." "We can make our composite
    with 0-40vol% HA and this gives a range of radiographic densities,
    40vol% is close to bone."

    Regards

    Adam Cutler
