Abstract
An apparatus for use in retaining vertebrae of a spinal column in a desired spatial relationship includes a longitudinal member extendable along the spinal column. A fastener for connecting the longitudinal member to a vertebra includes a first end portion for engaging a vertebra and a second end portion connectable with the longitudinal member. A staple including a plurality of mounting projections for engaging the vertebra has surfaces for defining an opening through which the second end portion of the fastener extends. The staple includes surfaces for engaging the second end portion of the fastener to prevent relative rotation between the fastener and the staple.
