Procedure radiograph orientation devices and methods of use are provided for stabilization and orientation of a patient's anatomy for a variety of surgical interventions. Additionally, devices of the present invention aid in orienting radiographic imaging devices through the inclusion of radiopaque fiducials so as to optimize radiographic images by providing radiographic reference landmarks.;An example of the present invention includes a rostral base plate, a plurality of support slats, and a caudal base plate, these components being adapted to pivot about one another or in certain embodiments, adapted to pivot about a series of spacers. One or more tension wires extend through the slats and base plates, joining the elements. The devices may be secured in various configurations by increasing the tension of the tension cable(s). Visual sighting or aiming devices may also be included in certain embodiments. Certain embodiments may include a rigid base plate having radiopaque fiducials. |

1. A procedure radiograph orientation device comprising:
an elongated rostral base plate having a first elongated edge and a second elongated edge with an aperture extending therebetween, wherein the second elongated edge thereof is adapted to receive at least partially a spacer; a caudal base plate having a first elongated edge and a second elongated edge with an aperture extending therebetween, wherein the first elongated edge thereof is adapted to receive at least partially a spacer; a plurality of elongated support slats, each support slat having a first elongated edge and a second elongated edge with an aperture extending therebetween, wherein the first and second elongated edges are adapted to receive at least partially a spacer; a first tension cable extending through the apertures of the elongated rostral base plate, the plurality of elongated support slats, and the elongated caudal base plate; a first tension adjuster for adjusting a tension of the first tension cable; wherein the plurality of elongated support slats are disposed successively adjacent one another between the rostral base plate and the caudal base plate so that the elongated edges thereof are substantially parallel, the elongated support slat closest to the rostral base plate being a first support slat and the elongated support slat closet to the caudal base plate being a last support slat; a plurality of spacers wherein each spacer is disposed between each of the plurality of support slats, between the rostral base plate and the first support slat, and between the last support slat and the caudal base plate; wherein one or more of the plurality of spacers are radiopaque, the one or more radiopaque spacers being referred to as horizontal fiducials; and a first vertical fiducial secured to one of the following: the rostral base plate, the caudal base plate, and at least one of the elongated support slats, wherein the first vertical fiducial is radiopaque. |
