1. A device for advancing a screw into tissue, the device comprising:
a screwdriver having a central shaft with a longitudinal axis and a distal end configured for attachment to a screw and an inner lumen for receiving a guidewire;
a retaining device for holding the guidewire fixed relative to the screw as the screw is advanced in a distal direction, wherein the retaining device is movably coupled to an outer surface of the central shaft and comprises a first locking element for fixing a position of the guidewire within the central shaft of the screwdriver, wherein the central shaft comprises a second locking element for fixing a longitudinal position of the retaining device relative to the central shaft; and
a release device for releasing the guidewire from the screw and holding the guidewire fixed relative to the longitudinal axis as the screw is advanced in the distal direction, wherein the release device comprises a release member for releasing the second locking element and allowing the retaining device to move in a longitudinal direction relative to the central shaft, wherein the central shaft comprises a longitudinal groove and the retaining device comprises a pin configured to move through the longitudinal groove.
