    • One embodiment of a spinal fixation system 10 including a pair of longitudinal members 11, 12 positionable adjacent the spine, means for engaging longitudinal members to the spine 13, 14, a pair of wedge members 16 each having a bearing surface 38 configured to bear on a longitudinal member 11, 12, and a connector 20 configured to span a distance between the longitudinal members 11, 12. The connector 20 includes a pair of engaging members 25, 26 each having a fixation surface 33 and a connecting surface 30, and a bridge member 21 attached to the connecting surfaces 30. The engaging members 25, 26 each define a thru-hole 35 for receiving one of the wedge members 16. The thru-holes 35 are aligned so that wherein one of the wedge members 16 is advanced through the thru-hole 35, the bearing surface 38 will bear on a corresponding longitudinal member 11, 12 to force the longitudinal member 11, 12 into contact with the fixation surface 33 and engage the longitudinal member 11, 12 to the connector 20.
    • 脊柱固定系统10的一个实施例,其包括可邻近脊柱定位的一对纵向构件11,12,用于将纵向构件接合到脊柱13,14的一对楔形构件16,每个楔形构件16具有构造成承受 纵向构件11,12和连接器20构造成跨越纵向构件11,12之间的距离。连接器20包括一对接合构件25,26,每个接合构件具有固定表面33和连接表面30,并且 桥接构件21附接到连接表面30.接合构件25,26各自限定用于容纳楔形构件16中的一个的通孔35.通孔35对准,使得楔形构件16中的一个前进 通过通孔35,支承表面38将承载在相应的纵向构件11,12上,以迫使纵向构件11,12与固定表面33接触,并将纵向构件11,12与接头 演员20。
