a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw, the body extending in a vertical direction along a longitudinal axis and extending in a horizontal direction along a widthwise axis;
a side portion including a first aperture extending through a side surface thereof and defining a first passageway configured to permit a tether to pass therethrough in the horizontal direction; and
a threaded aperture extending through an upper surface of the side portion and into the first passageway;
a set screw disposed in the threaded aperture,
wherein the set screw is configured to be rotated from an open position in which the tether is permitted to pass through the first passageway to a closed position in which the tether is immobilized within the first passageway;
wherein a medial portion of the first passageway comprises a circular indentation having a size and shape corresponding to a size and shape of a flattened bottom surface of the set screw.
