Abstract: A plug-on module for pushing onto a free end of a shaft formed for implantation in a long bone, comprising a holding body with an axial bore for the shaft at its lower end and a joint head as a part of a joint endoprosthesis, wherein the joint head is offset downwards in the axial direction from the upper end of the holding body sufficiently far and in such a way that the shaft protrudes upwards beyond the joint head. With such a quasi-offset arrangement the range of usage for the plug-in module is extended to cases in which previously a shorter through-going shaft would have been required and therefore a troublesome adjustment operation to exchange the through-going shaft would have to have been carried out.

Abstract: A fixation apparatus comprises a holder and a tension sleeve receiving a bone screw, wherein the bone screw has a shaft with a front thread and a head at the rear end, and the holder has a through borehole with a receiving seat, in which the tension sleeve is mounted and able to swivel, while the shaft has a thickening in a rear region, to the front of the head, whose width increases toward the head, and the width of the tension sleeve is larger than the width of the shaft immediately before the thickening and smaller than the greatest width of the thickening. When screwed in, the thickening widens the tension sleeve so that it is pressed by its envelope against the wall of the receiving seat. In this way, an angle-stable pressing is achieved for any given orientation of the bone screw.

Abstract: A fusion implant for a facet joint comprises a bearing module and a fusion module, in which the fusion model is arranged on the bearing module and has a holder for a transfacetal fastener, whereby the bearing module includes an expansion element and jaw elements, which have contact surfaces for the lamina on their outer sides moving away from each other and which are arranged to move longitudinally on a guide, so that the distance of the fusion module is changeable using the expansion element. The bearing module forms a secure and safe anchoring for the fusion module, which can be repositioned. In addition, the bearing module has the effect of an augmentation, and as a result treatment is possible even on vertabrae that are weakened by defects.

Abstract: An intervertebral fusion implant for the fusion of two vertebrae comprises an upper bearing body for placing on a lower end-plate of a vertebra, a lower bearing body for placing on an upper end-plate of a vertebra, and a central piece arranged between the bearing bodies. The central piece comprises a claw coupling which, in a coupling position, couples the two bearing bodies in a rotationally fixed manner to each other. In an open position of the claw coupling, the bearing bodies are freely movable in relation to each other. The claw coupling is actuated automatically via a plastic blocking body which, in its initial position, holds the claw coupling open and, under a load transferred from one vertebra to the other vertebra, is slowly deformable until it reaches a final coupling position in which the claw coupling is closed. This results in the slow fusion of the vertebrae.

Abstract: A reinforcing implant anchors shafts of two prostheses which are arranged opposite each other on an elongated bone, in particular a femur. The implant has a generally elongated shaft-like shape and a receiving sleeve at both ends for a respective anchoring shaft and a disconnectable coupling piece lying between the receiving sleeves for a rigid connection. In this manner, a force bridge is formed between the two anchoring shafts so that the bone is no longer subjected to the force transmission in particular in the sensitive intermediate region between the two anchoring shafts.

Abstract: A reinforcing implant for the lamina of a vertebra includes a transverse support, one anchoring device for the right-hand side and one anchoring device for the left-hand side of the lamina of the vertebra. An expansion element with a guide device and cheek elements is provided, the cheek elements being mounted to be longitudinally movable along the guide device. Bearing surfaces for the lamina are formed on outer faces of the cheek elements directed away from each other, and a return stop for the cheek elements is provided. At least one of the cheek elements is provided with an aligning device for modifying the orientation of its bearing surface relative to the guide device. In this way, a secure anchoring of the reinforcing implant on the resected surfaces produced during a laminectomy can be achieved, with precise adaptation of the reinforcing implant to the actual anatomical conditions following the laminectomy.

Abstract: An endoprosthesis component and a method for producing an endoprosthesis component is disclosed. The endoprosthesis component comprises a body predefining the shape of the endoprosthesis component. On surface portions with which the endoprosthesis component in the implanted state is in contact with human tissue, the body is covered with an outer layer which comprises a nitride, an oxynitride or an oxide based on a refractory metal and which contains silver and/or copper. An intermediate layer is arranged between the outer layer and the body in such a way that parts of the intermediate layer are accessible from the outside. The endoprosthesis component enables generation of a long-term antimicrobial action with the outer layer and, in addition, action on the surrounding tissue from the intermediate layer.

Abstract: A reinforcement implant comprises a cantilever part for spanning a resected area of a lamina and an anchoring part at opposite ends of the cantilever part. The first anchoring part has a pressure surface for bearing on the spinous process of the vertebra, and the second anchoring part has a transverse thrust surface for bearing on an outer face of the lamina. The pressure surface and the transverse thrust surface enclose an obtuse angle. An anti-shear device (e.g., a facet screw) is arranged on the transverse thrust surface, and one edge of the transverse thrust surface is adjoined by a load-bearing area of the cantilever part. The implant can thus be mounted in place from outside without needing to be pushed with a load-bearing action into the resected area. The resection surfaces on the lamina are free of loads, such that unevenness does not cause problems.
