摘要：
A bone screw includes an elongate shaft extending longitudinally between a proximal end and an opposing distal end The shaft bounds a first passageway at least partially extending between the proximal end and the distal end. The shaft is comprised of a radiolucent material. A core is disposed within the first passageway of the shaft. The core can be comprised of a radiolucent or radiopaque material. A head is either integrally formed with or secured to the proximal end of the shaft or the proximal end of the core. The head can also bound a second passageway that extends through the head and is aligned with the first passageway. The core can also be disposed within the second passageway.
