Methods and apparatus provide for: (i) coupling a spinous process plate to one lateral side of a spinous process of a spine of a patient, the spinous process plate extending substantially parallel to a sagittal plane (anterior-posterior plane) through the spine of the patient, the spinous process plate including a first fixation element facilitating a connection of the spinous process plate to the one lateral side of the spinous process; (ii) coupling a laminar plate to a laminar on the one lateral side of the spinous process of the spine, the laminar plate extending transversely from the spinous process plate and transversely to both the sagittal plane and a coronal plane (lateral plane) through the spine of the patient, the laminar plate including a second fixation element facilitating a connection of the laminar plate to the laminar on the one lateral side of the spinous process; (iii) engaging a sub-laminar hook to the laminar on the one lateral side of the spinous process, the sub-laminar hook extending transversely from the laminar plate and substantially parallel to a transverse plane through the spine of the patient, the sub-laminar hook extending and hooking beneath the laminar on the one lateral side of the spinous process of the spine; and (iv) extending a rod toward a pedicle on the one lateral side of the spinous process of the spine of the patient, the rod having proximal and distal ends, the proximal end being connected to the laminar plate and the rod extending from the laminar plate toward the pedicle, where the rod prohibits movement of bone associated with a fracture in a pars interarticularis of a vertebral arch on the one lateral side of the spinous process of the spine.
