Abstract
An occipital plate for use in an occipitocervical fixation procedure to stabilize the base of a patient'"'"'s skull with respect to the patient'"'"'s neck. The occipital plate of the invention is made up of a middle portion having left and right sides, and left and right hinged legs extending outward in opposite directions from the left and right sides of the middle portion. Each of the left and right hinged legs uses a hinge mechanism to secure a spinal rod to the occipital plate.

2. An occipital plate comprising:
-
a middle portion having opposite left and right sides; a left hinged leg extending from the left side of the middle portion, the left hinged leg comprising a left rotatable leg portion and a left stationary leg portion, the left rotatable leg portion and the stationary leg portion each having proximal and distal ends, wherein the proximal end of the left stationary leg portion is connected to the left side of the middle portion, and the distal end of the left stationary leg portion is connected via a left hinge to the proximal end of the left rotatable leg portion; and a right hinged leg extending from the right side of the middle portion, the right hinged leg comprising a right rotatable leg portion and a right stationary leg portion, the right rotatable leg portion and the stationary leg portion each having proximal and distal ends, wherein the proximal end of the right stationary leg portion is connected to the right side of the middle portion, and the distal end of the right stationary leg portion is connected via a right hinge to the proximal end of the right rotatable leg portion, wherein the distal ends of the left and right rotatable leg portions each define a through hole, and the proximal ends of the left and right stationary leg portions each define a hole therein, wherein during normal operation of the occipital plate the distal ends of the left and right rotatable leg portions can rotate and align respectively with the proximal ends of the left and right stationary leg portions such that the holes of in the distal ends of the left and right rotatable leg portions align respectively with the holes in the proximal ends of the left and right stationary leg portions, and wherein the middle portion defines a plurality of through holes.

3. An occipital plate comprising:
-
a middle portion having opposite left and right sides; a left hinged leg extending from the left side of the middle portion, the left hinged leg comprising a left rotatable leg portion and a left stationary leg portion, the left rotatable leg portion and the stationary leg portion each having proximal and distal ends, wherein the proximal end of the left stationary leg portion is connected to the left side of the middle portion, and the distal end of the left stationary leg portion is connected via a left hinge to the proximal end of the left rotatable leg portion; and a right hinged leg extending from the right side of the middle portion, the right hinged leg comprising a right rotatable leg portion and a right stationary leg portion, the right rotatable leg portion and the stationary leg portion each having proximal and distal ends, wherein the proximal end of the right stationary leg portion is connected to the right side of the middle portion, and the distal end of the right stationary leg portion is connected via a right hinge to the proximal end of the right rotatable leg portion, wherein the distal ends of the left and right rotatable leg portions each define a through hole, and the proximal ends of the left and right stationary leg portions each define a hole therein and the middle portion defines a plurality of through holes including a through hole located proximate to the left side of the middle portion and a through hole located proximate to the right side of the middle portion, wherein during normal operation of the occipital plate the distal end of the left rotatable leg portion is rotatable such that the through hole located at the distal and of the left rotatable leg portion aligns with the hole proximate to the left side of the middle portion, and wherein during normal operation of the occipital plate the distal end of the right rotatable leg portion is rotatable such that the through hole located at the distal and of the right rotatable leg portion aligns with the hole proximate to the right side of the middle portion.
