ABSTRACT:
An apparatus for maintaining vertebrae of a spinal column in a desired spatial relationship includes a longitudinal member extendable along the spinal column. A fastener connects the longitudinal member to a vertebra. The fastener has a first end portion engaging a vertebra and a second end portion. A staple, through which the second end portion of the fastener is extendable, includes a plurality of projections for engaging a vertebra. A washer, including an opening through which the second end portion of the fastener is extendable, engages the staple and the longitudinal member. The washer prevents pivotal movement of the longitudinal member relative to the staple. The longitudinal member, the fastener, the staple, and the washer are connected together.
