Abstract:
1. A connector assembly for interconnecting a bone fastener and a spinal rod, the connector assembly comprising: a connector extending generally along a first rotational axis and having a first end and a second end disposed in co-axial orientation to one another, the first end defining a first cavity around an assembly axis and the second end of the connector comprising an extension element having a generally cylindrical outer surface comprising axial splines circumferentially disposed about the outer surface each extending parallel to the first rotational axis, wherein the first end of the connector includes a disk having an upper splined surface and a lower splined surface and defines the first cavity around the assembly axis for receiving a threaded shaft of the rod receiver; a spinal rod receiver having a receiver body configured to be disposed beneath the connector and having a second cavity disposed around the assembly axis, the second cavity configured for receiving a spinal rod, the spinal rod receiver configured to substantially circumscribe the spinal rod and contact the first cavity of the connector for selectively adjusting the direction of at least a portion of the rod and/or connector in a coronal plane; a compression member for securing at least a portion of the rod in the receiver body, the compression member configured to be disposed above the connector and contact the first cavity of the connector and the spinal rod receiver, wherein the spinal rod is rotatable to a selected angular orientation for fixation with the first end of the connector; and a washer having an upper splined surface configured to mate with the lower splined surface of the disk.
