Abstract

An inserter for a bone screw assembly includes a hollow outer shaft with an inner shaft concentrically disposed therein. The distal ends of the inner shaft and outer shaft each define a feature for engaging the bone screw assembly. A collar is concentrically disposed about the proximal end of the inner shaft and a rotational interface is provided between the collar and inner shaft. The rotational interface is configured so that rotation of the collar relative to the inner shaft moves the collar into abutting engagement with a hub defined at the proximal end of the outer shaft. This abutting engagement locks the inner and outer shafts together when the distal ends of the shafts are engaged to the bone screw assembly for use in introducing the bone screw assembly into a bone.
