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: The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae, comprising an adjustable support body, the base surface and cover surface of which are configured to bear on end plates of the adjacent vertebrae, wherein provision is made for a side bracket, which can be pivoted laterally about a hinge and the base and cover of which have a planar design, and provision is made for an actuator for pivoting out the side bracket into a position (working position) spread from the support body. As a result, the implant has particularly small dimensions and can, after assembly at the envisaged implantation site, be actuated in such a way that it becomes larger and thereby affords a larger support surface for support in the intervertebral space. Thus, even comparatively large-area defects can be treated by minimally invasive surgery.

Abstract: A fixing arrangement comprises a retaining element and a clamping sleeve which receives a bone screw. The bone screw has a head and a secondary thread and is pivotally mounted in the clamping sleeve. The clamping sleeve has a radially protruding section on the outer casing of the clamping sleeve and at least one track of a clamping thread, which complements the secondary thread, in the interior of the clamping sleeve. In the unclamped state, a free path is formed by a clearance on the clamping sleeve. A protruding section engages into an opening on the receiving seat in a formfitting manner, and the thickened section is shaped to expand towards the rear in the form of a cone. The cone angle is selected such that the free path divided by the tangent of the half-cone angle corresponds to 0.5 to 2.5 times the thread pitch of the secondary thread.

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.

Abstract: Improved adhesive between a sheet material having a low free energy surface, such as a polyolefin, polystyrene, or polyethylene terephthalate film, is achieved by treating the film surface with a silane coupling agent that provides hydrolyzable groups on the surface of the film, and employing an adhesive composition comprising a polymer having reactive silyl groups (e.g., silyl-functionalized polyethers, polyurethanes and/or polyesters). Such improved sheet products can be advantageously employed as weather barriers for building construction applications, eliminating the need for, and disadvantages of, mechanical fasteners.
