ABSTRACT:
An apparatus for use in retaining spinal elements in a desired spatial relationship includes a fastener for engaging a spinal element. A longitudinal member is positionable along the spinal column. A connector member interconnects the fastener and the longitudinal member. The connector member has a mounting section with surface means defining a first opening through which the fastener extends. The longitudinal member extends through a second opening in the connector member. The axis of the opening through which the longitudinal member extends is perpendicular to top and bottom surfaces of the connector member. The mounting section has a side surface extending at an acute angle to the top and bottom surfaces. The connector member includes a surface that is parallel to the longitudinal axis of the opening through which the longitudinal member extends. The side surface of the mounting section extends at an acute angle to the surface of the connector member which is parallel to the longitudinal axis of the opening through which the longitudinal member extends.
