    • An interspinous implant includes a spacer having an upwardly facing concave saddle and a downwardly facing concave saddle. The lateral sides of the implant are pulled inward to force the saddles vertically away from each other, thereby increasing the effective height of the implant. In one version, a strap extends circumferentially around the anterior and posterior surfaces of the spacer, such that tightening the strap causes the saddles to move away from each other. In another version, the spacer includes a first outwardly facing convex segment disposed on a first lateral side of the saddles and a second outwardly facing convex segment disposed on a second lateral side of the saddles. A rod extends between the first and second convex segments and is fixed to the first convex segment and movable relative to the second convex segment.
    • 椎间植入物包括具有向上的凹形鞍座和面向下的凹形鞍座的间隔件。 植入物的侧面被向内拉,以迫使鞍座彼此垂直远离,从而增加植入物的有效高度。 在一个版本中,带子围绕间隔件的前表面和后表面周向延伸,使得紧固带子使得鞍座彼此远离地移动。 在另一个版本中,间隔件包括设置在鞍座的第一横向侧上的第一向外的凸起部分和设置在鞍座的第二横向侧上的第二向外的凸起部分。 杆延伸在第一和第二凸形段之间并且固定到第一凸形段并且可相对于第二凸形段移动。

    • A retaining mechanism engages a bone fastener to a bone plate as the bone fastener is positioned through a retaining mechanism in a plate hole while preserving multi-axial capabilities of the fastener relative to the plate during insertion of the fastener. When the head of the fastener is positioned adjacent the plate, the head can optionally be received in the retaining mechanism and expand the retaining mechanism to fixedly engage the retaining mechanism into locking engagement with the plate and lock the bone fastener in position relative to the plate. In another form, the multi-axial capabilities of the bone screw is preserved or at least partially preserved when the bone fastener is finally positioned in the retaining mechanism.
    • 保持机构将骨固定件接合到骨板上,因为骨紧固件通过板孔中的保持机构定位,同时在插入紧固件期间保持紧固件相对于板的多轴能力。 当紧固件的头部定位成邻近板时,头部可以可选地被容纳在保持机构中并且膨胀保持机构以将保持机构固定地接合到与板锁定接合并且将骨固定件相对于板锁定在适当位置 。 在另一种形式中,当骨紧固件最终定位在保持机构中时,骨螺钉的多轴能力被保留或至少部分保留。
