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.

Radiolucent screw with radiopaque marker

A stabilizing rod includes an elongate shaft extending between a proximal end and an opposing distal end. The shaft is comprised of a radiolucent material and bounds a passageway that at least partially extends between the proximal end and the distal end. A core is disposed within the passageway of the shaft. The core can be comprised of a radiopaque material. The stabilizing rod can also include a radiopaque marker disposed on or within the shaft.

Radiolucent stabilizing rod with radiopaque marker

A bone screw includes an elongate shaft extending longitudinally between a proximal end and an opposing distal end, the shaft bounding a first passageway at least partially extending between the proximal end and the distal end, the shaft being comprised of a radiolucent material. A core is disposed within the first passageway of the shaft, the core being comprised of a radiopaque material. A rounded head or a substantially U-shaped collar is either integrally formed with or is rigidly attached to the proximal end of the shaft.

A bone fixation plate assembly includes a proximal plate having a proximal body with a first arm projecting therefrom, the first arm having an elongated expansion slot extending through a portion thereof and a threaded bore formed thereon so as to communicate with the expansion slot. A set screw is received within the threaded bore and has a top surface with a driver engaging feature formed thereon and an encircling perimeter edge. A distal plate has a distal body with a first sleeve projecting therefrom. The first sleeve bounds a socket with the first arm received therein. An access opening is formed on the first sleeve and is configured so that the driver engaging feature of the set screw is accessible through the access opening while at least a portion of the perimeter edge of the set screw is covered by the first sleeve.

Modular bone fixation plate assembly

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.
