ABSTRACT:
An instrument to insert a modular screw into a substrate while allowing for removal of the instrument without disturbing the inserted modular screw. The instrument generally includes a first member that is cannulated. A second member of the instrument engages the modular screw shank. A compression force and locking engagement is created between the modular screw and the instrument which holds the modular screw in the instrument during the insertion of the modular screw. After the modular screw shank has been inserted, the second member of the instrument is removed from the first member which allows for the first member of the instrument to rotate freely around the modular screw. In this way, the instrument can be removed from the modular screw without disturbing the modular screw after implantation.
