Abstract
A hand instrument and method for use by a surgeon to target the appropriate entry point and trajectory on bony tissue through which an instrument, such as a nail, pin, screw, rod, wire, drill bit, or other implant is passed. Imbedded within the instrument is at least one relatively radio-opaque target which allows the user to predict with the use of an x-ray or fluoroscopic imaging device the placement of said instrument or implant before drilling it into place with the use of an x-ray or fluoroscopic imaging device. By manipulating the device around the axis of the guide piece, the surgeon can predict the placement of the instrument or implant without iterative insertion and removal of the instrument or implant itself.
