1. A guide assembly comprising:
a reduction tool; a spinal rod guide comprising an upper threaded portion, the upper threaded portion configured to threadingly receive a threaded portion of the reduction tool; a spinal screw assembly comprising a bone screw and a spinal rod holder, the spinal rod holder comprising an intermediate threaded portion and a lower threaded portion; a fastener, the fastener configured to be threadingly received by the intermediate and lower threaded portions and to engage a surface of a spinal rod; wherein the spinal rod guide and the intermediate threaded portion are detachably coupled to the remainder of the spinal rod holder such that the intermediate and lower threaded portions of the spinal rod holder enable a user to thread the fastener along both the intermediate threaded portion and the lower threaded portion of the spinal rod holder in a continuous manner prior to detachment of the spinal rod guide and the intermediate threaded portion from the remainder of the spinal rod holder; and wherein an end of the reduction tool is configured to engage the fastener such that the threaded portion of the reduction tool disengages the upper threaded portion of the spinal rod guide prior to the fastener engaging the intermediate threaded portion of the spinal rod holder.
