    摘要： A bone spreader includes two tubular pin holders which are connected to one another by a parallel guide system, and two pins that are configured to be connected to the bone parts that are to be spread apart. In order to give the bone parts that are to be spread apart a more secure position in relation to one another, at least one of the pin holders is provided with a locking device for a pin located in the pin holder. This locking device includes a locking finger which is movable tangentially with respect to the pin holder and which, in the locking position, engages in a transverse groove of the associated pin and can be formed by a pivotably mounted hook.

    摘要： An intervertebral disc prosthesis having two cover plates and a prosthesis core that extends to the circumferential edge of the cover plates. The prosthesis core is mounted to the lower cover plate and forms a spherical sliding surface with the upper cover plate. The connection surface of the cover plates may be set back from the circumferential perimeter of the cover plates to provide an optimum size of the spherical sliding surface despite the set-back nature of the connection surface. The set-back is configured as an inclined transition surface that adjoins the connection surface to the circumferential edge. The set-back allows the intervertebral disc prosthesis to be fully inserted into the prepared disc space into the spared dorsolateral corners without protruding ventrally.

    摘要： An intervertebral prosthesis, in particular for the cervical spine, includes a first cover plate to be connected to a first vertebral body, second cover plate to be connected to the second vertebral body, and a prosthesis core which forms an articulation with the second cover plate. The prosthesis core is held by seat of the first cover plate which is designed as a guide device. The core can be pushed into the guide device from the ventral side in the anterior-posterior (AP) direction relative to the first cover plate. A limit-stop plate is provided on the ventral edge of the first cover plate. This limit-stop plate is displaceable in a slide guide between a locking position and a nonlocking position.

    摘要： An instrument for inserting an intervertebral prosthesis, comprising two prosthesis holders which are connected by a parellel guide and can be spread apart from one another and are intended to receive a pair of prosthesis plates. The first prosthesis holder is arranged fixedly on an elongate instrument body. The second prosthesis holder is held from the instrument body by means of a parallel guide. The parts connecting the second prosthesis holder to the instrument body or to the first prosthesis holder delimit on both sides a central through-opening which extends like a channel in the longitudinal direction of the instrument body and whose width corresponds at least to the transverse dimensions of a prosthesis core, to be inserted between the prosthesis plates, and of the prosthesis core holder provided for this.

    摘要： The invention relates to an endoprosthesis for replacement of a joint, in which slide surfaces that have different contours and correspondingly define movement planes for bearing are formed by an intermediate part. According to the invention, the intermediate part has a projection, preferably a convex projection, on at least one side face, in order to avoid fibrosis.

    摘要： Surgical instrument for inserting an intervertebral endoprosthesis consisting of two prosthesis plates and a prosthesis core. The instrument has two prosthesis holders open at the ends that can be spread apart from each other. In order not to have to remove the instrument from the prosthesis with the latter being under unfavourable loading, it is provided with a withdrawal device which bears on the prosthesis and/or on an associated vertebra. The withdrawal device comprises a slide having a prosthesis limit stop for the prosthesis located in the guide and/or a vertebral limit stop for a vertebra which is to be connected to the prosthesis. The slide is displaceable in a slide guide between a retracted end position and an advanced end position by an actuating device.
