Abstract
An apparatus for coupling with a fixation rod to allow spinal compression, distraction, and fixation along an antero-lateral aspect of a spine includes an elongated plate, first and second fixation screws, and a first arm. The elongated plate includes a first aperture at a superior end and a second aperture at an inferior end. The first fixation screw is received by the first aperture and engages a first body portion of a first vertebra. The second fixation screw is received by the second aperture and engages a second body portion of a second vertebra. The first arm extends transversely from a first base portion on the elongated plate and includes a first hook to couple with a first portion of the fixation rod.
