Abstract
A multiaxial receiver may include 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 multiaxial receiver may include a first passageway configured to permit a tether to pass therethrough in the vertical direction. In some embodiments, the multiaxial receiver may also include a second passageway configured to permit a tether to pass therethrough in the horizontal direction. An immobilization assembly including a set screw and a wedge may immobilize the tether. The immobilization assembly may be 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 or second passageway by pining the tether against a bearing surface of the first passageway.
