ABSTRACT:
An apparatus for retaining vertebrae of a spinal column in a desired spatial relationship includes a fastener having a first end portion for engaging a vertebra. A connector member interconnects the fastener and a longitudinal member positionable along the spinal column. The connector member includes a clamp for clamping the longitudinal member to the connector member. The fastener extends through a slot in the connector member to permit adjustment of the distance between the axis of the fastener and the axis of the longitudinal member. The axis of the fastener is spaced from the clamp a distance measured along the axis of the longitudinal member when the connector member interconnects the fastener and the longitudinal member.
