In order to achieve additional levels of fixation, the CD HORIZON® Spinal System rods may be connected to the VERTEX™ Reconstruction System with the VERTEX™ rod connector. When connecting to the VERTEX™ Reconstruction System in the cervical spine, components are intended for the following indications:
When intended to promote fusion of the cervical spine and the thoracic spine, (C1-T3), the VERTEX™ Reconstruction System is indicated for the following:
DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors.
Hooks and Rods
The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine.
Multi-axial Screws/Lateral Connectors
The use of VERTEX™ multi-axial screws (3.5mm and 4.0mm cancellous, and 4.0mm cortical) is limited to placement in T1-T3 in treating thoracic conditions only. The multi-axial screws are not intended to be placed in the cervical spine.
Titanium ATLAS™ Cable and the CD HORIZON® Spinal System may be used with the VERTEX™ Reconstruction System.
The CD HORIZON® Spinal System consists of a variety of rods, hooks, screws, CROSSLINK® plates, staples, and other connecting components, as well as implant components from other Medtronic Sofamor Danek spinal systems, which can be rigidly locked in a variety of configurations, with each construct being tailor-made for the individual case. If necessary, the CD HORIZON® Spinal System can be connected to the VERTEX™ Reconstruction System through a rod connector.
Certain implant components from other Medtronic Sofamor Danek spinal systems can be used with the CD HORIZON® Spinal System. These components include TSRH® rods, hooks, screws, plates, CROSSLINK® plates, connectors, staples and washers; GDLH® rods, hooks, connectors and CROSSLINK® bar and connectors: LIBERTY® rods and screws: DYNALOK PLUS® bolts; and Medtronic Sofamor Danek Multi-Axial rods and screws. Please note that certain components are specifically designed to connect to 4.5mm, 5.5mm diameter rods, while other components can connect to both 5.5mm and 6.35mm rods. Care should be taken so that the correct components are used in the spinal construct.
CD HORIZON® hooks are intended for posterior use only. CD HORIZON® staples and CD HORIZON® ECLIPSE® rods and screws are intended for anterior use only. However, for patients of smaller stature, CD HORIZON® 4.5mm rods and associated components may be used posteriorly.
The CD HORIZON® Spinal System implant components are fabricated from medical grade stainless steel. Alternatively, the entire system may be made out of medical grade titanium or titanium alloy. Never use stainless steel and titanium implant components in the same construct.
The CD HORIZON® Spinal System also includes anterior staples made of Shape Memory Alloy (Nitinol - NiTi). Shape Memory Alloy is compatible with titanium implants only. Do not use with stainless steel.
The purpose of this 510(k) submission is to add modified CD HORIZON® cannulated screws to the system.
The provided document does not contain information about specific acceptance criteria or a study designed to prove that the device meets those criteria. Instead, it is a 510(k) premarket notification for the CD HORIZON® Spinal System, which primarily focuses on establishing "substantial equivalence" to a legally marketed predicate device.
The relevant section, "V. Substantial Equivalence," explicitly states:
"Documentation was provided which demonstrated the CD HORIZON® Spinal System to be substantially equivalent to itself."
This indicates that the submission is for modifications or additions to an existing device within the same product line, and the primary demonstration of safety and effectiveness relies on its similarity to an already cleared version of the CD HORIZON® Spinal System.
Therefore, I cannot populate the requested table or provide answers to most of the questions, as the document does not describe:
- Specific performance metrics or acceptance criteria for the device itself (beyond general safety and effectiveness implied by substantial equivalence).
- A dedicated study to prove these criteria are met.
- Details regarding test sets, ground truth establishment, expert qualifications, or comparative effectiveness studies.
The document is a regulatory filing for a medical device and not a detailed clinical or performance study report.
§ 888.3060 Spinal intervertebral body fixation orthosis.
(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.
