  • Patent number: 11304822
    Abstract: Disclosed is a device for assisting in the placement of a trapeziometacarpal prosthesis including a cup to be fixed in the trapezium of a patient and a stem to be fixed in the patient's first metacarpal. The device includes a first guide to be interposed between the trapezium and the first metacarpal, the first guide including a first body having a first surface to be positioned on the articular surface of the trapezium, the first surface congruent with the articular surface of the trapezium and a second surface to face the articular surface of the first metacarpal before resection, the second surface preferably being congruent with the articular surface of the first metacarpal so as to be positionable on the articular surface of the first metacarpal. The first guide also includes locating members carried by the first body and arranged to define resection lines for the first metacarpal.

  • Publication number: 20210322001
    Abstract: A bone anchoring device includes first and second arms defining a first slot of depth p extending along an axis. The first and second arms respectively bear a first and a second branch extending outside the first slot. The first branch defining second and third slots. In the rest position: the orthogonal projection on the axis of the bottom of each of the second and third slots is in the first slot distanced from the bottom of this slot of at least 10% of p; and the distances d1 separating the second slot bottom from the part of the end of the branch defining it which is the furthest away from it, and d2 separating the third slot bottom from the part of the end of the branch defining it which is the furthest away from it, so each of d1/p and d2/p>0.3.

  • Patent number: 10993751
    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.
