Claim 0:
1. An apparatus for treating a fracture in a pars interarticularis of a vertebral arch on a lateral side of a spinous process of a spine of a patient, the fracture having a length and defining a first part of the fractured pars interarticularis and a second part of the fractured pars interarticularis, the apparatus comprising:
a spinous process plate extending substantially parallel to a sagittal plane (anterior-posterior plane) through the spine when implanted, the spinous process plate including a first fixation element configured to attach the spinous process plate to the lateral side;
a 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 when implanted, the laminar plate including a second fixation element configured to attach the laminar plate to a laminar on the lateral side;
a sub-laminar hook extending transversely from the laminar plate and substantially parallel to a transverse plane through the spine when implanted, the sub-laminar hook configured to extend and hook beneath the laminar on the lateral side;
a rod having proximal and distal ends, the rod extending substantially perpendicular to the length of the fracture, from the laminar plate toward a pedicle on the lateral side when implanted, the rod anchored in a configuration that prohibits movement of the first and second parts of the fractured pars interarticularis relative to one another when implanted;
a coupling element coupling the proximal end of the rod to the laminar plate where the coupling element includes features that require the rod to extend along an axis that does not intersect or pass over either of the first fixation element or the second fixation element; and
a third fixation element coupling the distal end of the rod to the pedicle on the lateral side when implanted.
