Abstract
A hook device for use with support rod implantation apparatus is disclosed which is positionable along the central axis of the posterior surface of the spine and has independently rotationally positionable blade and head portions. The head portion is engageable with a deflecting top cylindrical portion which sits above the lamina. The insertion, and subsequent locking of a rod in the rod receiving channel of the head portion causes the blade portion and the head portions to be compression locked together by virtue of an interference fit.
