Abstract
The embodiment of a spinal fixation system 10 including a pair of longitudinal members 11, 12 positionable adjacent the spine, engaging member 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 when 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.
