Abstract: A bone anchoring device is provided that includes an anchoring element with a shank to be anchored in a bone or a vertebra, a connection element for connecting at least two anchoring elements, the connection element being made of an elastic material, a receiving part being connected to the shank for receiving the connection element and connecting the connection element to the shank, a seat for the connection element the seat being provided in the receiving part, and a locking element being engageable with the receiving part for fixation of the connection element in the seat. At least the portion of the connection element which is received in the recess has a substantially smooth-surface. The locking element has an engagement structure which contacts the surface of the connection element in such a way that a form-fit connection is provided.

Abstract: A Spinal column implant for elastic stabilization of vertebrae includes an elastic rod that is anchored in a non-positive fit fashion in the receptacle of a pedicle screws by means of a mobile filling piece and a clamping element. The non-positive fit is supported additionally by a dynamic form-fit contribution upon exposure to load.

Abstract: A spinal column implant for elastic stabilization of vertebrae, includes a pedicle screw and an elastic rod which is anchored in a frictional fashion in a receptacle of pedicle screws by means of a filling piece, and a clamping element. The frictional connection is supported additionally by an indirect form-fit portion.

Abstract: A vertebral column implant for the elastic stabilization of motion segments (1, 2) comprising an eleastically bendable connecting element (5) which can be passed through the seats (4) of a number of pedicle screws (3) having offset seat axes (6a, 6b, 6c) and be anchored.

Abstract: A vertebral column implant for the elastic stabilization of motion segments (1, 2) comprising an elastically bendable connecting element (5) which can be passed through the seats (4) of a number of pedicle screws (3) having offset seat axes (6a, 6b, 6c) and be anchored. The connecting element is bendable elastically about every axis of its cross-section in such a way that the connecting element can be passed through, or inserted in, the seats of the screwheads, one behind the other, even when the seats are not situated on one and the same axis. The connecting element and the seat in the screwhead each have wholly, or in part, a structured surface, in such a way that the structured surface of the seat engages the structured surface of the connecting element, and shifting can be prevented in assembled condition.

Abstract: A pedicle screw with a closure device comprises a seat element and a closure cap for quick closure of the seat element of the pedicle screw. An elastic rod element inserted therein in the seat recess, which element serves to stabilize a vertebral column, is held in a form-locking way. The closure cap of the closure device has the function of a cross-brace, and can transfer the forces absorbed by it from the rod element to the pedicle screw. Disposed on the closure cap with a holding recess are engagement means which, during insertion of the closure cap, automatically lock in place in a stable position in the seat element provided with a U-shaped seat recess. The seat recess and the holding recess preferably have a ridged or grooved structure corresponding to the rod element used.

Abstract: An implant, in particular an intervertebral prosthesis, which consists of an elongated elastic body which is form-elastic and takes on the form of a spiral S in the force free state. The spiral can be drawn by a reverse winding up into an insertion instrument which is only insubstantially larger in the insertion region than the cross-section of the elongated elastic body in order to reach the inner space of an intervertebral disc through a small opening in the annulus fibrosus and to push in and sever off the self winding spiral when the interior is filled. This has the advantage that inner spaces of differing sizes can be filled with the same spiral.

Abstract: The invention discloses a fastening system for pedicel screws anchorable in different vertebrae. The spherical screw heads lie in spherical shells of apertured counter-bodies. The counter-bodies have planar support surfaces which lie on a supporting link in the region of elongate holes. A screw element is provided in the axial direction of each pedicel screw and is pivotably journalled at the supporting link with a spherical support surface arranged in the region of the elongate hole. The pedicel screws are generally skewed relative to one another and can, when account is taken of the nature of the bone, be rigidly connected to the supporting links via the screw elements due to the fact that the support surfaces can be clamped against one another in a self-locking manner on pedicel screws which are positioned inclined relative to the support surfaces.

Abstract: The implant may be used as prosthetic replacement for a ligament and/or tendon. The implant has a plurality of discrete longitudinal strands disposed in side-by-side relation with transverse filaments about the strands. Individual sub-zones of the ligament are folded over in a transverse manner about a longitudinal axis of the sub-zone with intermediate zones being in an unfolded state. The intermediate zones may be formed solely of longitudinal strands to enhance flexibility.

Abstract: A prosthetic ligament implant is sheathed at one end in the sock in order to facilitate pulling of the implant through a hole drilled in a bone. The sock is provided with a separable proximal portion which does not envelope the implant and which can be cut off after pulling of the implant through the hole in the bone. With removal of the proximal portion, the remaining textile structure of the sock becomes asunder so that the sock can be readily pulled off from the end of the implant.

Abstract: The pull-through appliance is made of a mesh structure formed of at least one continuous thread and a pullout thread disposed at one end of the mesh structure to prevent unraveling of the mesh structure. A hollow tube is used to facilitate drawing in of the synthetic strand and autologous strand of the prosthesis. After removal of the hollow member, the resulting package can be readily threaded through a bore in a bone. After implantation, the pull-out thread is removed and the mesh structure unraveled so as to remove the mesh structure from within the bone.
