No
The device is described as a "Posterior Stabilization System" intended to provide "immobilization and stabilization of spinal segments" as an "adjunct to fusion." This indicates a therapeutic, rather than a diagnostic, purpose.
No
The device description explicitly states it is a "multiple component, posterior stabilization system" consisting of various physical implants (rods, screws, caps, etc.) and associated manual surgical instruments made of Titanium Alloy. This indicates it is a hardware-based medical device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description: The ORTHROS™ systems are described as implants (rods, screws, etc.) made of titanium alloy, designed for surgical implantation to stabilize the spine.
- Intended Use: The intended use is to provide immobilization and stabilization of spinal segments as an adjunct to fusion in the treatment of various spinal conditions. This is a surgical intervention, not a diagnostic test performed on a sample.
The device is a surgical implant used in the body, not a device used to test samples from the body.

Reason for 510(k) Submission
This 510(k) is being submitted to address the MIS intended use of these implants in their labelling. The new intended use and the system components for MIS system including the "long towers" was introduced as part of note to file for the existing 510k K133366, but a recent review of the regulatory strategy by an outside regulatory council resulted in a decision to file a 510k for the addition of this intended use. This traditional 510(k) also documents the changes to the ORTHROS™ Posterior Stabilization System that have occurred since its clearance in K133366. These devices include cross links, anti-rotation rods, solid reduction screws, and instrumentation. The additions and minor modifications to the ORTHROS™ Posterior Stabilization System, subject to applicant's risk management system, do not change the previously cleared ORTHROS™ Posterior Stabilization System (K133366) indications for use, contraindications, warnings, or precautions, and do not raise new issues of safety or effectiveness. Camber Spine Technologies believes that the ORTHROS™ MIS Posterior Stabilization System is substantially equivalent to the primary predicate, Camber Spine Technologies ORTHROS™ Posterior System (K133366), and the additional predicate Orthofix Firebird Spinal Fixation System/Phoenix MIS Spinal Fixation System (K171082).
