Abstract: An orthopaedic method and anchor assemblies for anchoring a linkage such as a rod or cable used for fixation or reduction. One assembly includes an anchor plate and a slotted anchor bolt that captures the plate in a one-piece assembly for convenient installation. The base of the anchor bolt lies below the plate, and a cap or nut tightens down to secure a linking member, e.g., a rod or cable, in the slot, simultaneously clamping the bolt to fix both its position and its orientation on the plate. One occipital plate has lateral arms that hold the anchor bolts, and a Y-shaped embodiment is mounted in an inverted orientation to position the anchor bolts well down in soft tissue for more effective wound closure. A cable connector is used together with an anchor plate, vertebra anchor screws and fixation rods to secure ends of a cable at the level of one or more vertebrae, providing a versatile and highly stable system for alignment, fixation and fusing of the cervical and thoracic spine.
