An apparatus for a spinal fixation generally includes a hook member and a linkage. The hook member includes an upper portion and a lower portion. The lower portion has a generally arcuate shape and defines an aperture passing therethrough. The lower portion has a curved shape for engaging the lamina. The linkage includes a generally flat plate and defines an arcuate service for matingly receiving the upper portion of the hook member so as to permit relative rotation therebetween. The apparatus further includes a coupling arrangement including a shaft passing through the recess of the linkage and an aperture of the hook member. The shaft includes an upper end and a lower end. A locking member is carried by a lower end and disposed within an aperture of the hook member. A nut is provided in threaded engagement with the upper end of the shaft.
