Abstract
A conical interspinous apparatus includes a distractor comprising an insertion portion and a central engagement groove, the insertion portion having a conical shape which tapers to a tip and is adapted to enable passage of the distractor between two spinous processes of vertebrae, and the central engagement groove is adapted to secure the distractor between the two spinous processes such that the two spinous processes rest in the central engagement groove. The conical interspinous apparatus includes a stabilizer which is adapted to be deployed from within the distractor to secure the two spinous processes within the central engagement groove and an insertion driver detachably coupled to a rear portion of the distractor. A guide wire, having a pointed tip, aids in the insertion of the distractor between the two spinous processes and is configured to guide the insertion of the distractor.
