  • Publication number: 20030097180
    Abstract: The present invention provides a joint prosthesis system for the joining of two bones. The bioabsorbable joint prosthesis system includes at least one bioabsorbable spacer and at least one connector adapted to be fixedly attached to the two bones, at least a portion of the connector being in contact with the spacer to prevent lateral movement of the spacer. The present invention also includes embodiments drawn to methods of using the joint prosthesis system. In an embodiment of the present invention, the method includes interposing at least one bioabsorbable spacer between the surface of the bones to be joined and connecting the bones with at least one connector such that at least a part of the connector contacts the bioabsorbable spacer.

  • Patent number: 6113640
    Abstract: A cylindrical, fibrous, porous joint spacer is provided, having excellent properties, flexibility of formation, and operability, which is intended to be implanted as a prosthesis between bones to be joined together. The joint spacer of the present invention can be formed from a strip of fabric, which is comprised of bioabsorbable fibers and made by a knitting, weaving, non-woven or other technique. The fabric is typically relatively narrow (e.g. 1 to 10 mm wide) and thin (e.g. 0.1 to 1.0 mm thick), depending on the intended application of the prosthetic device to be formed from the fabric. The joint spacer of the present invention is made by wrapping said fabric to yield a cylindrical body; and fixing the free end of the fabric to the surface of the cylindrical body so formed. The joint spacer of the present invention can be implanted in conjunction with one or more fixation parts, to hold the joint spacer in place between the bones to be joined.
