Abstract
For treating a fracture in a pars interarticularis, methods and apparatus provide for: (i) coupling a spinous process plate to a lateral side of a spinous process of a spine of a patient, the spinous process plate extending substantially parallel to a sagittal plane through the spine, the spinous process plate including a first fixation element configured to attach the spinous process plate to the lateral side; (ii) coupling a laminar plate to a laminar on the lateral side, the laminar plate extending transversely from the spinous process plate and transversely to both the sagittal plane and a coronal plane through the spine, the laminar plate including a second fixation element configured to attach the laminar plate to the laminar on the lateral side; (iii) engaging a sub-laminar hook to the laminar on the lateral side, the sub-laminar hook extending transversely from the laminar plate and substantially parallel to a transverse plane through the spine, the sub-laminar hook configured to extend and hook beneath the laminar on the lateral side; (iv) extending a rod toward a pedicle on the lateral side, the rod having proximal and distal ends and extending substantially perpendicular…
