• The Synthes 319.17 Measuring Device is a relatively simple but essential instrument in the 4.5 mm cannulated screw system. Its primary role is to help the surgeon determine the exact length of screw needed after drilling is done but before the actual screw is inserted. It is used by advancing it over the guide wire (which has been placed in the intended trajectory), to touch or approach the bone surface or target point, then reading off measurement markings (or using calibrated distance) to match with the screw length scale.
• In design, the measuring device must be cannulated (i.e. have a central lumen) so it can slide over the guide wire used in the cannulated screw technique without displacing the wire. It needs to be rigid enough to resist flex or bending over its length, to maintain accuracy, yet fine enough to work in conjunction with the narrow guide wires and drill sleeves typical of this system. Though I couldn’t locate published values for its length, marking increments, or diameter, instruments of this type typically have calibration markings in millimeters, and are sized to accommodate the standard 4.5 mm screw system’s guide wires and sleeves.
• Clinically, using the measuring device is crucial to reducing intraoperative guesswork. It is used after drilling and before insertion, often under imaging (fluoroscopy) to verify depth, and fits into the surgical workflow as one of the basic and reusable instruments.
