Abstract: Methods for non-pedicle spinal fixation. In some implementations, at least one plate member may be placed between an upper spinous process and a lower spinous process of a spine. At least one scissoring element coupled to the at least one plate member may then be positioned to contact opposing lateral surfaces of the upper spinous process and to contact opposing lateral surfaces of the lower spinous process. The at least one scissoring element may then be locked into place to stabilize the spinous processes.

Abstract: Spinal distraction apparatus includes at least one plate member having upper and lower surfaces adapted for placement between opposing upper and lower spinous processes having outer lateral surfaces. A pair of scissoring elements are hingedly affixed to the plate member to engage with the lateral surfaces of the spinous processes. A device is provided for locking the scissoring elements in position once a desired degree of contact is made. In a preferred configuration, the scissoring elements are sandwiched between a pair of opposing plate members, each having upper and lower surfaces adapted for placement between opposing upper and lower spinous processes, and the inner surfaces of the scissoring elements are concave. The device for locking the scissoring elements in position is a fastener that extends through a central portion of both scissoring elements and the plate members.
