    • A method for performing spinal fixation and instrumentation for accomplishing the same is disclosed. The spinal fixation system and instruments may include an insertion guide operably connected to a screw or hook for insertion into a vertebrae. The insertion guide may have first and second longitudinal slots creating flexible arms for attachment to the screw. The slots are preferably sufficiently wide to permit the insertion of a spinal rod therethrough to be received in a channel in the screw. The insertion guide has a bore and preferably is sized to be inserted through a minimally sized passageway to the vertebrae. A sleeve may be positioned into one insertion guide in a first position to guide a rod through at least one other insertion guide. The sleeve may be rotated to a second position to allow the rod to move down the slots of the insertion guide(s) and into the head portion of the screw. Holding instruments to facilitate placement and angulation of the rod are also disclosed.
    • 公开了一种用于执行脊柱固定和仪器的实现方法。 脊柱固定系统和器械可以包括可操作地连接到用于插入椎骨的螺钉或钩的插入引导件。 插入引导件可以具有第一和第二纵向槽,其形成用于附接到螺钉的柔性臂。 狭缝优选地足够宽以允许脊柱杆穿过其中以容纳在螺钉中的通道中。 插入引导件具有孔,并且优选地被定尺寸成通过最小尺寸的通道插入到椎骨中。 套筒可以在第一位置被定位到一个插入引导件中,以引导杆穿过至少另一个插入引导件。 套筒可以旋转到第二位置,以允许杆向下移动插入引导件的槽并进入螺钉的头部。 还公开了用于促进杆的放置和成角度的保持装置。

    • A method for total replacement of an affected intervertebral disc through a dorsal approach comprising the steps of removing the disc material of the affected intervertebral disc (3) and inserting an intervertebral prosthesis (30) into the intervertebral disc space via an extraforaminal path (23). An intervertebral prosthesis (100), in particular an intervertebral disk prosthesis comprising A) a first prosthetic component (101) having a first apposition surface (107) disposed transversely to the central axis (103) B) a second prosthetic component (102) having a second apposition surface (108) disposed transversely to the central axis (103); whereby C) said first and second prosthetic components (101; 102) are connected by means of an articulation (106); whereby D) when viewed parallel to said central axis (103) said first and second prosthetic components (101; 102) have an elongated shape with a major axis (127) and a transverse minor axis (128); E) said central axis (103), major axis (127) and transverse minor axis (128) intersecting each other and said central axis (103) and transverse minor axis (128) defining a middle plane (126); F) said first and second prosthetic component (101; 102) have a cross-sectional area orthogonal to said central axis (103) which is essentially oval or elliptical; whereby G) said cross-sectional area comprises at least two concavities (125; 130) lying on different sides of said middle plane (126) and on the same side of said major axis (127).
    • 一种用于通过背侧方法完全替换受影响的椎间盘的方法,包括以下步骤:移除受影响的椎间盘(3)的椎间盘材料并且经由椎间孔径路径(23)将椎间假体(30)插入椎间盘空间中, 。 一种椎间假体(100),特别是一种椎间盘假体,包括:A)第一假体部件(101),其具有相对于中心轴线(103)横向布置的第一对接表面(107); B)第二假体部件 横向于所述中心轴线(103)设置的第二对齐表面(108); 其中C)所述第一和第二假体部件(101; 102)通过铰接(106)连接; 其中D)当平行于所述中心轴线(103)观察时,所述第一和第二假体部件(101; 102)具有带长轴(127)和横短轴(128)的细长形状; E)所述中心轴线(103),主轴线(127)和横向副轴线(128)彼此相交,所述中心轴线(103)和横向副轴线(128)限定中间平面(126); F)所述第一和第二假体部件(101; 102)具有与所述中心轴线(103)正交的横截面,该横截面基本上为椭圆形或椭圆形; 其中G)所述横截面区域包括位于所述中间平面(126)的不同侧面上和所述长轴(127)的同一侧上的至少两个凹陷(125; 130)。
