Rotatable bone plate

Abstract

Bone plates and assemblies for stabilizing bony structures. More particularly, the bone plates having an elongate body to which an integrated rod is formed. Integrated rod portion may be captured by a bone anchor with a receiving member. The bone plate is movable from a first position to a second position and may have an aperture for lagging the bone plate to the bone.

         4 . The bone plate assembly of  claim 1 , wherein the bone plate fastener is secured with a locking element to prevent back out of the bone plate fastener from the plate portion. 
     
     
         5 . The bone plate assembly of  claim 1 , wherein after the first or second integrated rod portion is secured in the receiving member of the bone fastener, the plate portion is movable between a first position and a second position. 
     
     
         6 . The bone plate assembly of  claim 5 , wherein in the first position the elongate plate body provides access to an intervertebral space and in the second position the elongate plate body is orientated to provide maximum stabilization between said two bony structures. 
     
     
         7 . The bone plate assembly of  claim 6 , wherein said bony structures are vertebral bodies. 
     
     
         8 . The bone plate assembly of  claim 1 , wherein a lower surface of the plate portion is configured to generally match the curvature of the bony structures to which it is attached. 
     
     
         9 . The bone plate system of  claim 1 , wherein the first and second integrated rod portions are configured to be positioned on a posterior aspect of a vertebral body and the at least one aperture for receiving the bone plate fastener is configured to be positionable on an anterior aspect of the vertebral body. 
     
     
         10 . A bone plate assembly for stabilizing at least two bony structures, comprising:
 an elongate plate having a plate portion and first and second integrated rod portions, the elongate plate body having a longitudinal axis extending from a first end to a second end of the plate portion and comprising at least one aperture, the first and second integrated rod portions extending beyond the first and second ends of the plate portion in a direction parallel to the longitudinal axis, wherein the first integrated rod portion extends in a first direction away from a center of the plate portion and the second integrated rod portion extends in a second direction, opposite to the first direction, away from the center of the plate portion;   a first bone fastener having a first receiving member with a U-shaped body for receiving the first integrated rod portion and a first cap for securing the first integrated rod portion in the first receiving member and a second bone fastener having a second receiving member with a U-shaped body for receiving the second integrated rod portion and a second cap for securing the second integrated rod portion in the second receiving member; and   a bone plate fastener configured to be inserted through the at least one aperture and threaded into a first vertebral body thereby moving the plate portion directly into contact with said first vertebral body.   
     
     
         11 . The bone plate system of  claim 10 , wherein the first and second integrated rod portions are generally cylindrical in shape. 
     
     
         12 . The bone plate system of  claim 10 , wherein the first and second integrated rod portions have a textured surface. 
     
     
         13 . The bone plate assembly of  claim 10 , wherein the bone plate fastener is secured with a locking element to prevent back out of the bone plate fastener from the plate portion. 
     
     
         14 . The bone plate assembly of  claim 10 , wherein after the first and second integrated rod portions are secured in the first and second receiving members of the first and second bone fasteners, respectively, the plate portion is movable between a first position and a second position. 
     
     
         15 . The bone plate assembly of  claim 14 , wherein in the first position the elongate plate body provides access to an intervertebral space and in the second position the elongate plate body is orientated to provide maximum stabilization between said two bony structures. 
     
     
         16 . The bone plate assembly of  claim 15 , wherein said bony structures are vertebral bodies. 
     
     
         17 . The bone plate assembly of  claim 10 , wherein a lower surface of the plate portion is configured to generally match the curvature of the bony structures to which it is attached. 
     
     
         18 . The bone plate system of  claim 10 , wherein the first and second integrated rod portions are configured to be positioned on a posterior aspect of a vertebral body and the at least one aperture for receiving the bone plate fastener is configured to be positionable on an anterior aspect of the vertebral body.
