  • Publication number: 20250152215
    Abstract: The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30° and 60° in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.

  • Publication number: 20160135815
    Abstract: One aspect of the present invention relates to a tissue resection guide that includes a central body, a first flange and a second flange, the flanges having first and second guide surfaces, respectively, suitable for use in tissue resection. Each guide surface lies on a cutting plane, both planes intersecting interior to the flanges. In the embodiments described, the availability of two cutting planes ensures resections in more than one plane are possible. As a result, bone segments can be removed via a cut on two planes without the need to cut across an entire section of bone on one plane. In some embodiments, an opening exists between the first flange and the second flange to ensure that each resection overlaps. In other aspects of the invention, systems and methods of use for the tissue resection guide are described.

  • Publication number: 20150066094
    Abstract: A plate is disclosed for compressing together first and second bone parts. The plate includes screw holes adapted to receive screws for insertion into first and second bone parts, respectively, at least one of the screw holes being a compression slot with formations configured to ensure, when a respective screw is seated within the slot, an adjustable compression force adapted to bring the first and second bone parts closer together. The plate also comprises a circular guide pin hole for insertion of a pin into one of the first and second bone parts, and another guide pin hole, in the form of an elongate slot, for insertion of a pin into the other of the first and second bone parts. The plate may also include a curvature adapted to cause at least a pair of screws inserted into screw holes of the plate to converge.

  • Publication number: 20110264148
    Abstract: The plate is fixed by screws (3) engaged in holes (1a) formed in the thickness of the plate which is designed in such a way as to ensure an adjustable compression effort, created by a screwing effect, which brings the two bone parts closer together. The design consists of at least one recess (1b) having a cross-section defining a plurality of separate areas (1b1), (1b2) and (1b3) that can co-operate with a screw (3) in order to generate a progressive translational movement of the screw (3) during the screwing action, corresponding to a movement of at least one of the bone parts, and causing the compression effort. Said plate (1) comprises a recess (1c) for the introduction of a spindle (4) on the side of one of the bone parts, and another recess (1d) for the introduction of a spindle (5) on the side of the other bone part, one of said recesses (1c) consisting of a circular hole having a diameter which essentially corresponds to that of the spindle (4), and the other recess (1d) consisting of an oblong hole.
