Abstract
Disclosed is an axial and rotational stopping device for use when creating threads in a predrilled pilot hole or inserting an allograft bony void filler or synthetic implant into a threaded hole. The device can also provide consistent depth control for drilling a pilot hole, tapping the hole to create threads, and implanting an allograft bony void filler or synthetic implant while preventing damage to the threads in the tapped hole that would be caused by continuing to rotate a tap once the depth stop has been reached and the tap can no longer advance in the axial direction, as well as preventing damage to the threads in the tapped hole, the threads on the mating allograft bony void filler or synthetic implant, and the drive features on either the driver instrument or the allograft bony void filler or synthetic implant.
