1. A guide assembly kit for reducing a spinal rod, the guide assembly kit comprising:
a reduction tool comprising a threaded portion;
a guide assembly comprising:
a rod guide portion comprising an upper threaded portion and a non-threaded portion, the non-threaded portion comprising at least one transverse slot; and
a spinal rod holder coupled to the rod guide portion and configured to receive a spinal screw and the spinal rod, the spinal rod holder comprising an intermediate threaded portion spaced apart from the upper threaded portion by the non-threaded portion, and a lower threaded portion forming a continuous threaded portion with the intermediate threaded portion, wherein a fracture joint joins the intermediate threaded portion and the lower threaded portion, and wherein the lower threaded portion and the intermediate threaded portion have substantially consistent thread pitches;
wherein the threaded portion of the reduction tool engages the upper threaded portion of the rod guide portion in a first configuration;
wherein the threaded portion of the reduction tool disengages the upper threaded portion of the rod guide portion in a second configuration with the reduction tool advanced in the spinal rod holder toward the lower threaded portion; and
wherein the at least one transverse slot enables application of a torque to the rod guide portion to cause fracture of the fracture joint and enable removal of the rod guide portion and the upper threaded portion of the spinal rod holder from a remainder of the spinal rod holder.
