A spinal stabilization system comprising: first and second pedicle screws each comprising a threaded base and a screw head attached to the threaded base, the treaded base of the first pedicle screw to be connected to a first superior pedicle of a vertebra and the threaded base of the second pedicle screw to be connected to a second superior pedicle of the vertebra; and at least one pars interarticularis clamp comprising an elongated curved body having a first end and a second end; characterized in that the screw head is a poly-axial screw head, the first end of the curved body is configured to be received by the poly-axial screw head of the first pedicle screw, and the second end of the curved body is configured to be received by the poly-axial screw head of the second pedicle screw, andthe at least one pars interarticularis clamp further comprises a laminar hook coupled to the curved body and configured to wrap around an edge of the lamina; wherein the poly-axial screw heads of the first and second pedicle screws are configured to ratchet and compress the first and second ends of the curved body, respectively, to lock them in place so that the laminar hook applies a compression force to compress the pars interarticularis of the vertebra. first and second pedicle screws each comprising a threaded base and a screw head attached to the threaded base, the treaded base of the first pedicle screw to be connected to a first superior pedicle of a vertebra and the threaded base of the second pedicle screw to be connected to a second superior pedicle of the vertebra; and at least one pars interarticularis clamp comprising an elongated curved body having a first end and a second end; characterized in that the screw head is a poly-axial screw head, the first end of the curved body is configured to be received by the poly-axial screw head of the first pedicle screw, and the second end of the curved body is configured to be received by the poly-axial screw head of the second pedicle screw, andthe at least one pars interarticularis clamp further comprises a laminar hook coupled to the curved body and configured to wrap around an edge of the lamina; wherein the poly-axial screw heads of the first and second pedicle screws are configured to ratchet and compress the first and second ends of the curved body, respectively, to lock them in place so that the laminar hook applies a compression force to compress the pars interarticularis of the vertebra. the screw head is a poly-axial screw head, the first end of the curved body is configured to be received by the poly-axial screw head of the first pedicle screw, and the second end of the curved body is configured to be received by the poly-axial screw head of the second pedicle screw, andthe at least one pars interarticularis clamp further comprises a laminar hook coupled to the curved body and configured to wrap around an edge of the lamina; wherein the poly-axial screw heads of the first and second pedicle screws are configured to ratchet and compress the first and second ends of the curved body, respectively, to lock them in place so that the laminar hook applies a compression force to compress the pars interarticularis of the vertebra. <EOS>
