1. A system adapted to be implanted in a patient to stabilize a spinal column of the patient comprising:

  • an anchoring plate having a shape generally conformal with at least a portion of a lamina associated with a targeted vertebra of the spinal column, the anchoring plate including;

    a first threaded hole to receive a first screw having a shank and a head, the first threaded hole adapted to direct the first screw into the targeted vertebra and restrict orientation of the shank to a first angle and/or range of angles relative to the sagittal plane while the first screw is advanced along the first threaded hole,a second threaded hole to receive a second screw having a shank and a head, the second threaded hole adapted to direct the second screw into the targeted vertebra and restrict orientation of the shank to a second angle and/or range of angles relative to the sagittal plane while the second screw is advanced along the second threaded hole, anda third threaded hole to receive a third screw having a shank and a head, the third threaded hole adapted to direct the third screw into the targeted vertebra and restrict orientation of the shank to a third angle and/or range of angles relative to the sagittal plane while the third screw is advanced along the third threaded hole, andwherein the angle of orientation of the shanks of the first, second, and third screws relative to the sagittal plane vary and/or the range of angles of orientation of the shanks of the first, second, and third screws relative to the sagittal plane do not overlap.
