The invention also relates to an external fixator, having at least one such connecting apparatus and a device for ambulatory emergency care comprising an external fixator.

Abstract: An intervertebral implant with two opposite contact surfaces configured to bear regionally on vertebral bodies and are spaced apart from each other along a vertical axis and are each arranged on support elements which are adjustable relative to each other. The support elements are guided adjustably relative to each other along a circular arc contour oriented on a longitudinal axis extending perpendicular to the vertical axis in such a way that, by adjustment of the two support elements relative to each other along the circular arc contour, a spacing of the two contact surfaces with respect to the vertical axis and/or an angle setting of the two contact surfaces relative to each other can be predefined and/or modified.

Abstract: An implant for the stabilization and/or fusion of the sacroiliac joint has an elongated, spiraled exterior shape. The implant has a conically tapered inner core with a passage opening which extends in the axial direction along a central longitudinal axis over the entire axial length of the implant and ribs which run outward in a radial manner at least sectionally and which are arranged on the inner core and extend helically in the axial direction around at least one section of the inner core.

Abstract: An implant includes a body that defines an axis and has an interior. A counter element is disposed on the body to releasably fix a manipulating tool thereto. The counter element has at least two undercuts spaced apart relative to the axis of the body and each has a respective holding surface oriented towards the interior of the body. A bearing surface is on the counter element to rotationally fix the implant relative to the manipulating tool. The bearing surface is oriented non-coaxially with the axis of the body.

Abstract: An implant contains two end pieces disposed coaxially and at an axial distance, a cage, which connects the end pieces, and webs connecting the two end pieces. The two ends of each web are offset from each other by an equal initial angle in an initial state of the implant. The implant can be expanded by rotation of the end pieces in opposite directions about the center longitudinal axis. A tool for the implant has a handle and a main element with a receptacle for the implant and with two rotating devices, which act with a force fit on engaging elements of the implant and can be rotated oppositely in relation to each other.

Abstract: The invention relates to an instrument set for percutaneous stabilization of the spinal column using rods (8) and pedicle screws (1) that have a screw head (3) and a screw shank (4) and a distally open recess (13) for receiving a rod (8), with a screw manipulator (2) through which a central cavity (11) passes axially and which comprises a cylindrical sleeve (20) and a slide (24), wherein the wall of the cylindrical sleeve (20) is divided into two first wall segments (27) by two diametrically opposite and axially extending windows (26) which open out in the proximal end face of the sleeve (20), the proximal ends of the first wall segments (27) form grip elements (28) which, during a screw manipulation, receive between them at least a longitudinal portion of the screw head (3), and the slide (24) is displaceable in the axial direction on the sleeve (20) and is connected to the first wall segments (27) such that it secures these against moving radially apart at least in a proximal end position (E) of displace

Abstract: A manipulating tool for a medical implant includes an actuating rod. The rod has a rear end with a grip part and a fixing element at the front end for the releasable axial fixing of the implant. The implant has a counter element suitable for fixing, which has at least two undercuts spaced apart relative to an axis of its body with one respective holding surface oriented in the direction of the interior of the body. The manipulating tool has at least two clamping jaws being at a radial distance from the central longitudinal axis of the actuating rod, for engaging behind the undercuts on the implant side. The clamping jaws are spaced apart in the peripheral direction. A kit for implant medicine includes a medical implant and a corresponding manipulating tool.

Abstract: Embodiments are directed to bone-joining or bone-bridging intervertebral implants with an inner channel-type structure of channels, which extend parallel from a bone contacting-surface of the implant to the inside of the implant, whereby the channels are connected by lateral openings.

Abstract: A rod connector for transversely connecting two vertebral column rods has two clamps and a transverse bridge that fixes the clamps to each other. The clamps have a spring device with a spring force that is low enough to allow the clamp to be manually snapped onto the vertebral column rod, to be slid onto the same in the installed state, and to be released from same. An attaching device for the clamp, which is independent of the spring device, generates a retaining force that is high enough to solidly attach the clamp on the vertebral column rod in the installed state. The transverse bridge has a connection part with a frame for receiving a first branch connected to one clamp and with a ball rotatably mounted in the frame and having a second branch pass therethrough that connects to another clamp.

Abstract: A pedicle screw has a screw shaft and a screw head connected thereto. The screw head has a center longitudinal axis extending in an X-direction. The screw further has a recess for receiving a connecting rod with a circular cross-section, a fixing screw that is used to fix the connecting rod in the screw head, a clamping unit between the fixing screw and a head base and an intermediate element.

Abstract: A height-adjustable implant is designed to be inserted between vertebral bodies and includes a first and a second sleeve part. The second sleeve part carries an external thread and is inserted with a longitudinal section thereof in the first sleeve part in a rotationally fixed and axially movable manner. On its longitudinal section projecting from the first sleeve part, the second sleeve part is encompassed by a nut that engages with the external thread. The nut carries a toothed ring. The invention also relates to a tool for handling the implant.

Abstract: A height-adjustable implant for insertion between vertebrae, includes first and second sleeve parts which are rotationally fixed in coaxial alignment and interconnected in an axially displaceable manner. The first sleeve part has an internal thread. A nut is positioned coaxially in an inner space surrounded by the sleeve parts and is fixed to the second sleeve part so that it can rotate but is axially fixed. The nut has an external thread which engages in the internal thread of the first sleeve part. A toothed ring extends coaxially with the central longitudinal axis of the sleeve parts and is located on the nut. The second sleeve part has a radial access opening in the vicinity of the toothed ring. An operating instrument for activating the implant adjustment includes a handgrip and a shaft extending through the handgrip, a rotary grip carried on one end and another end carrying a toothed wheel for rotational actuation of the nut in the interior space of the implant.

Abstract: A height-adjustable spinal implant has first and second components that are rotationally fixed relative to one another and axially movable along a central longitudinal axis of the implant. Each of the components have at least two wall segments that are fixed on a base and that extend in the direction of the central longitudinal axis and are at a radial distance from the latter. Circumferentially adjacent wall segments each flank a space in which a wall segment of the respective other component extends and is axially guided. A drive element is disposed in the interior of the implant that engages with the second component in a meshing relationship. The drive element bears, in the load direction, on the first component and has a toothed ring that is used for its rotary actuation. For the rotary actuation of the drive element, an access opening is present in a wall segment of the first component. The free ends of the wall segments of the first component are connected to each other by a holding element.
