    • 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。
