Abstract: The invention relates to a plate-implant for use in osteosynthesis, comprising at least one first plate component with throughbores for receiving fastening screws and a connection means, at least one second plate component with throughbores for receiving fastening screws and a receiving means for receiving a connection means. According to the invention, each plate component is slidable in one direction relative to the other plate component, the plate components being provided with a device limiting their slide path relative to each other. The device comprises a clamping screw (18) having a thread and a screw head and, in the mounted state of the two plate components (2, 3), the thread cooperates with the connection means (5) and the screw head with a longitudinal borehole (14) provided in the second plate component (3) in such a way that a clamping effect is obtained between the screw head and the longitudinal borehole (14) and between the connection means (5) and the receiving means (6).

Abstract: The invention relates to a joint part prosthesis, particularly for a finger joint, consisting either of a proximal or a distal component as well as a shaft extending away from this component, to be mounted in a bone. The invention provides that the shaft (4) is at least partially formed as an expansion sleeve (7).

Abstract: A surgical instrument for implanting a wire, preferably into a bone, can be operated with one hand and thus acts as an extension of a surgeon's arm. The instrument is made up of a receiving element and a clamp part and also of a grip element. The grip element has two grip parts, the receiving element including the first grip part, and the clamp part including the second grip part. The receiving element has a recess for at least partial support of the wire, and the clamp part is mounted on the receiving element, so as to be able to move in rotation about a bearing point, and includes a clamp element which engages in the recess and is designed in such a way that, when the grip parts are pressed together, the clamp part presses the wire against the support.
