to multiple levels in the spinal column 18 more than one level may be addressed simply by lengthening the rods 66 and 68 and slideably positioning multiple pedicle screws 80 thereon for selective positioning along the spinal column in one aspect the cross member midpoint 64 may be configured structured and arranged to be adjustably e g pivotably or translatably connected or secured to the second end portion 56 of the body 52 at approximately the midpoint 64 in order to allow a surgeon during the course of the surgical procedure to adjust and align components of the implant in relation to the patient 39 s bony anatomy and in relation to support members 66 and 68 in another aspect elongate body 52 may be comprised of multiple pieces for example one or more linear racks may be configured in operable relation with gear mechanisms thereby forming a ratchet device not shown in order to extend the distance between first and second end portions 54 and 56 thereby permitting a surgeon during the course of the surgical procedure to adjust and align components of the implant in relation to the patient 39 s bony anatomy and subsequently securing them in place for example a ratchet mechanism configuration may permit the surgeon to progressively extend elements of the implant to better appose a lamina in yet another aspect each of the ends 60 62 of the cross member 58 may be configured to permit a degree.
