  • Patent number: 5397358
    Abstract: A bone implant is so designed that it consists of a main body, more particularly in the form of a core and unidirectional fibers, said core being surrounded by braided fiber configuration. The braided fiber configuration has an elevated fiber fraction in order to grain the surface of the braided structure. This grained surface aids the coalescent growth of natural bone tissue on the implant. The braided fiber configuration simultaneously serves as a torsion box.

  • Patent number: 5141521
    Abstract: In the method for the production of a hip joint prosthesis shank two shells are produced with unidirectional fibers, which extend in the longitudinal direction of the shank and prior to curing of matrix material therein the components are assembled so that during the later curing stage there is an intimate engagement produced between the components. The fibers are wound on a shape, which has the desired form of the shell, by winding a single fiber lengthwise of the form and reversing the fiber at the ends of the form. The winding is carried out by pulling the fiber taut along the length of the form and reversing the fiber at the ends on pins and relatively turning the form and the fiber after completing the winding of the fiber over the length of the form. The core may be produced by introducing foaming or liquid material into the cavity formed by the shells.
