    • An intervertebral implant (1), having an upper section (10) provided with a ventral side area (11), a dorsal side area (12), two lateral side areas (13,14), a top apposition surface (15) and a bottom surface (16); and a lower section (20) provided with a ventral side area (21), a dorsal side area (22), two lateral side areas (23,24), a bottom apposition surface (25) and a top surface (26). The two sections (10;20) are moveable in relation to each other by means of two joints (38;39) arranged between the two sections (10;20), the two joints (38;39) are realised by an upper joint section (31) connected to the upper section (10), a central joint section (32) and a joint section (33) connected with the lower section (20). One of the external joint sections (31;33) comprises at least one concave sliding surface (58) rotation-symmetrical with regard to a swivel axle (3;4); and the other of the external joint sections (31;33) comprises at least one convex sliding surface (55) rotation-symmetrical with regard to the other swivel axle (3;4).
    • 一种椎间植入物(1),具有设置有腹侧区域(11)的上部(10),背侧区域(12),两个侧面区域(13,14),顶部邻接表面(15)和 底表面(16); 以及设置有腹侧区域(21),背侧区域(22),两个侧面区域(23,24),底部邻接表面(25)和顶面(26)的下部区段(20)。 两个部分(10; 20)可以通过布置在两个部分(10; 20)之间的两个关节(38; 39)相对于彼此移动,两个关节(38; 39)由上部接头 连接到上部(10)的部分(31),与下部(20)连接的中心接合部分(32)和接头部分(33)。 一个外接头部分(31; 33)包括相对于旋转轴(3; 4)旋转对称的至少一个凹形滑动表面(58)。 并且所述外接头部分(31; 33)中的另一个包括相对于另一个旋转轴(3; 4)旋转对称的至少一个凸形滑动表面(55)。

    • Combining an implant and cement for prophylactic and/or preventative use for femoral neck augmention. A hole is drilled into the femoral neck. The hole is filled with an uncured filler cement after loose materials have been removed from the hole. Then, an open-ended tube, an implant, having openings through its walls is inserted into the hole and attached to the bone. Finally, additional filler cement is provided under pressure to the inside of the tubular implant. The filler cement flows into spaces in the bone structure via the tube wall openings. A sliding leak-tight fit between the implant and a cement injection tube permits delivery of cement at preselected locations along the implant length. Pressure is maintained until the filler cement has hardened. A strengthening factor up to 3 was measured when osteoporotic bone was strengthened.
    • 结合种植体和水泥,用于股骨颈扩大的预防和/或预防性使用。 在股骨颈上钻一个洞。 从孔中取出松散材料后,孔中填充有未固化的填料。 然后,将具有穿过其壁的开口的开口管,植入物插入孔中并附着到骨上。 最后,在压力下向管状植入物的内侧提供另外的填充胶。 填料粘合剂通过管壁开口流入骨结构中的空间。 在植入物和水泥注射管之间的滑动密封配合允许沿着植入物长度在预选位置输送水泥。 保持压力直到填料水泥硬化。 当骨质疏松骨被加强时,测量了高达3的强化因子。
