Cannulated Screw

Cannulated screws have a hollow central shaft. The advantage of a cannulated screw is that it can be inserted over a guide wire. The knowles pin is a specialized form of cannulated screw. Modern Grinding can manufacture custom cannulated screws to your specification.

Modern Grinding Cannulated Screws are made to order, please contact us for custom tips, sizes and threading.

Please note, we only make cannulated screws, we do not make additional fixation parts. We typically work with medical suppliers and medical researchers who have a specific cannulated screw in mind.
