Abstract
Spine fixation constructs are configured to receive and retain a spinal rod onto a vertebral bone screw. The spine fixation constructs provide for 360° rotation about a bone screw and variable axial placement about the bone screw. In one form, a rod holder of the spine fixation construct is configured to be axially received onto the bone screw. Axial positioning of the rod holder on the bone screw is fixed through cooperation of the rod holder with a fixation component. The fixation component is axially received onto the bone screw. Retention of the spinal rod by the spinal rod holder is also provided via the fixation member. In one form, spinal rod retention is provided upon axial retention of the spinal rod holder onto the bone screw through cooperating action between the fixation mechanism and the spinal rod holder. According to an embodiment, a member of the rod holder is caused to pivot and capture the spinal rod upon receipt of the fixation member onto the bone screw and rod holder. According to another embodiment, pivoting motion of a pawl of the rod holder by the fixation member not only locks the spinal rod but skews the pawl relative to the bone screw to wedge the axial placement of the pawl and thus the rod holder relative to the bone screw.
