  • Patent number: 8764809
    Abstract: The present disclosure relates to an implant for refixation of the greater trochanter on which an osteotomy has been performed or which is fractured. The implant comprises a plate that can be fixed on the proximal femur, and a device that can hold the greater trochanter with a form fit or force fit on the femur. This holding device preferably has bendable prongs located at a distance from each other, the first end portion of these prongs being attached to the upper edge of the base plate. The holding device also has flexible, elongate members, each of which is attached at one end to the free end portion of the respective prong. The other, free end portions of the longitudinal members are secured laterally on the base plate after these longitudinal members have crossed the medial aspect of the greater trochanter. This results in a tensioning band construction with at least two restraints based on a plate fixed securely on the proximal lateral femur.

  • Patent number: 8685022
    Abstract: A device (1) according to the invention for externally fixing broken bones (62, 62?) of a patient, particularly the extremities, comprises a support (11) composed of a plurality of joint elements (2, 2) that are stringed together, wherein said support can be disposed outside the body of the patient. The proximal ends (41) of at least two percutaneously disposed pins (4) are anchored in the bone tissue (61) of the patient, and the distal ends (42) are fixed to the support (11). The joint elements (2) are stringed on a central tensile force element (3), and in each case two adjoining joint socket (22). The individual ball joints, and thus the support (11), can be fixed in a reversible frictionally engaged manner by applying a tensile force of the central tensile force element (3). The joint elements (2, 2?) in turn are designed such that a pin (4) can be fastened to the support (11) in a clamping and/or frictionally engaged manner by applying the tensile force of the central tensile force element (3).
