ABSTRACT:
A vertically adjustable, self-centering spine screw including a bone screw with an beveled head. A series of lateral grooves are disposed on the bone screw head that mesh with similar grooves on an adapter. The second side of the adapter has radial splines that mesh with similar radial grooves on a spacer. This configuration gives the surgeon a self-centering bone screw with adjustment in both the lateral and angular directions.
