Abstract:
1. An implantable spinal fixation assembly for stabilization of spinous processes, comprising: a first plate component comprising an elongated plate and front and back cross plates extending at right angles to and from the front and back of the elongated plate, respectively; a top pivoting plate comprising a main body and an extending arm and wherein said extending arm comprises a first end pivotally attached to said front and back cross plates; a bottom pivoting plate comprising a main body and an extending arm and wherein said extending arm comprises a first end pivotally attached to said front and back cross plates; wherein said top and bottom pivoting plates are configured to form a K-shaped structure together with said elongated plate and to pivot around an axis perpendicular to said front and back cross plates; wherein said elongate plate comprises an inner surface facing an inner surface of the top pivoting plate and an inner surface of the bottom pivoting plate and wherein said inner surfaces of said elongated plate, said top and bottom pivoting plates are configured to engage and frictionally lock said plates onto first and second spinous processes positioned in a first space between said elongated plate and said top pivoting plate and a second space between said elongated plate and said top pivoting plate, respectively; and wherein said front and back cross plates are dimensioned to fit between said first and second spinous processes and comprise edges sculpted to conform to the shape of said spinous processes.
