  • Publication number: 20190167310
    Abstract: 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.

  • Patent number: 8801712
    Abstract: A bone plate has a main body configured to position adjacent bones with respect to each other. The main body includes a plurality of separate layers bonded together. Each layer is comprised of a radiolucent material and has a first aperture and a second aperture that extend through the layer. The layers are all stacked such that the first apertures of all of the layers are aligned with each other and the second apertures of all of the layers are aligned with each other. An insert can be positioned within the first aperture.
