Atlantis Translational Anterior Cervical Plate System
A ratcheting anterior cervical plate featuring segments that translate under compression, but maintain their position under tension, based on nonclinical testing. Clinical outcomes may vary.
How It Works
The Atlantis Translational® Anterior Cervical Plate System is a ratcheting plate featuring segments that translate under compression, but maintain their position under tension. Test results demonstrated that the unidirectional plate had less motion in flexion-extension and maintained a more consistent graft load when compared to bidirectional design.1,2 These comparative study test results are based on non-clinical testing. Clinical outcomes may vary.
This system is intended for use in temporary stabilization of the anterior cervical spine (C2-T1) during the development of spinal fusions in patients with: (1) degenerative disc disease, (2) trauma, (3) tumors, (4) deformity, (5) pseudoarthrosis, and/or (6) failed previous fusions.
Atlantis Translational Anterior Cervical Plate System
Unidirectional Translation
- Allows axial load-sharing between the graft and the vertebral body end plate.1
- Allows unidirectional translation up to 2 mm per level in 1mm increments.
- Unidirectional movement provides a continuous compressive load between the end plate and the bone graft based on nonclinical testing.1,2 Not indicative of human clinical outcomes.
- Allows intraoperative precompression.
- Adjustable plate allows flexibility of screw placement on vertebral body to fit pathology and patient anatomy (e.g., corpectomy, larger patients).
- Unidirectional mechanism allows the plate to function as a static plate when in the fully collapsed position.
Risks
There are potential risks associated with the use of these devices some of which include: disassembly, bending, and/or breakage of any or all of the components, screw loosening and/or back out, pressure on the skin from the device which could cause skin penetration, irritation, and/or pain, tissue or nerve damage and scar formation.
