  • Publication number: 20260069328
    Abstract: A device for treating a bone fracture, in particular a femur fracture such as a femoral neck break, includes a holding part fastenable in or on a first bone part, wherein the holding part has at least one opening through which a bone screw and an adjusting screw are guided. The opening includes on the inner side a surface having a threaded surface that the adjusting screw engages, with the bone screw being able to slide freely in the opening, and the adjusting screw is configured to allow the bone screw to rest against at least one stop of the adjusting screw, if necessary after a lateral sliding of the bone screw. An adapter that can be fixed in the bone screw to be laterally releasable forms a barrier for the adjusting screw in the event of lateral movement of the adjusting screw.

  • Publication number: 20260013878
    Abstract: Positioning device and method for positioning and/or fixing a bone implant, e.g., an intramedullary nail. The positioning device has a curved handle, having a target guide defining a target axis for guiding a bone drill device, a connection element for releasably connecting the bone implant to the curved handle and an alignment sight. The alignment sight has a first indicator for indicating the course of the target axis in a second X-ray image of the alignment sight along a target line of sight, which lies in a first alignment plane formed by the target axis and the first indicator structure. To provide an optimized handling, the alignment sight has a second indicator structure for indicating an orthogonal tilting of the line of sight from the first alignment plane in a first X-ray image of the alignment sight along a line of sight which deviates from the target line of sight.

  • Patent number: 8672940
    Abstract: An implant for osteosynthesis, for example a bone nail, has an implant body which has at least one bore with a threaded portion and a bone screw which engages the thread when it is threaded into a bone for the fixation of the implant body. The threaded bore has an annular groove the diameter of which is larger than the thread outer diameter, and which receives a ring of a deformable material with an inner diameter which is smaller than the outer diameter of the thread of the bone screw so that the ring extends partially into the bore.
