Abstract
Disclosed are skull fixation assemblies and corresponding components. The assemblies include a multi-axial occipito-cervical connection system that enables elongate interconnectors, such as rods, to be coupled in a manner that permits relative movement in one or more planes. The system includes a locking mechanism that can be actuated to lock the relative positions of the elongate interconnectors.
Claims35
A skull attachment assembly for spinal fixation, comprising:
- a skull attachment member adapted to be attached to a skull, the skull attachment member having a central member and first, second, and third arms extending outwardly from the central member, wherein the central body or the arms include at least one borehole adapted to receive a bone fastener for fastening the skull attachment member to a skull.
A skull attachment assembly, comprising:
- a skull attachment member configured to be attached to a skull, the skull attachment member including a rod-based skeleton that supports at least one extension that provides a platform for attaching the skull attachment to a component.
An assembly for retaining a bone graft, comprising:
- a device that rigidly affixes a bone graft in a fusion orientation from a skull to a cervical spine.
A skull-spine connection assembly, comprising:
- a connector adapted to connect at least two elongate spinal interconnectors to one another, the connector being adapted to transition between a locked state and an unlocked state, wherein the connector permits relative movement between the interconnectors throughout one or more planes when in the unlocked state, and wherein the connector immobilizes the interconnectors relative to one another when in the locked state.
A skull attachment assembly, comprising:
- a skull attachment device having a first borehole for receiving the shank of a bone screw;
- a protrusion extending upward from the skull attachment device;
- and
- at least one fixation assembly mounted on the protrusion, the fixation assembly configured to attach an elongate interconnector to the skull attachment device.
