    • An intervertebral implant having a three-dimensional body (10) and a securing plate (1). The three-dimensional body (10) includes an upper side (1) and an underside (2) which are suitable for abutting the end plates of two adjacent vertebral bodies, a left side surface (3) and a right side surface (4), a front surface (5) and a rear surface (6), a horizontal middle plane (7) between the upper side (1) and the underside (2), and a vertical middle plane (12) extending from the front surface (5) to the rear surface (6). The three-dimensional body further includes a plurality of boreholes (9a) passing through the body (10), which are suitable for accommodating longitudinal fixation elements (20). The intervertebral implant also includes a front plate (8) displaceably disposed as an insert with the front side (5) of the three-dimensional body, the front plate (8) having a plurality of boreholes (9) in which the longitudinal fixation elements (20) can be anchored, and whose openings overlap with the openings of the boreholes of the three-dimensional body (10). A securing plate can be fastened essentially parallel to the front plate (8) at the three-dimensional body (10) in such a manner that the boreholes of the front plate (9) are covered at least partly by the securing plate (18). By virtue of the configuration of the intervertebral implant, a rigid, firm connection between the intervertebral implant and the longitudinal fixation elements used to fasten it, is possible.

    • An intervertebral implant for implantation between an upper vertebra and a lower vertebra having a central axis. The implant may have a first member with a top surface for contacting at least a portion of the upper vertebra and a bottom surface as well as a second member with a top surface and a bottom surface for contacting at least a portion of the lower vertebra. An elastic spacer may be disposed between the first member and the second member. The bottom surface of the first member and the top surface of the second member may have a first constraint means and the other of the bottom surface of the first member and the top surface of the second member may be provided with a second constraint means, to limit the amount of lateral movement between the first and second members. Additionally, the constraint means may be sized and configured such that a gap with a width greater than zero is provided at least transversely to the central axis between the first and second constraint means in an unloaded state.
    • 用于植入在具有中心轴线的上椎骨和下椎骨之间的椎间植入物。 植入物可以具有第一构件,其具有顶表面,用于接触上椎骨的至少一部分和底表面以及具有顶表面和底表面的第二构件,用于接触下椎骨的至少一部分。 弹性间隔件可以设置在第一构件和第二构件之间。 第一构件的底表面和第二构件的顶表面可以具有第一约束装置,并且第一构件的底表面和第二构件的顶表面中的另一个可以设置有第二约束装置, 限制第一和第二构件之间的横向运动的量。 另外,约束装置的尺寸和构造可以使得在卸载状态下至少横向于第一和第二约束装置之间的中心轴线提供宽度大于零的间隙。
