No
The summary describes a mechanical spinal implant system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is described as an aid to fusion and is indicated for various spinal conditions, directly implying a therapeutic purpose.
No
Explanation: The provided text describes a medical device intended for spinal stabilization and fusion, specifically the NuVasive™ Triad™ Facet Screw System. Its purpose is to aid in treatment for various spinal conditions, not to diagnose them.
No
The device description clearly states that the system consists of physical components (screws and washers fabricated from titanium alloy) intended for surgical implantation. This is a hardware medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The NuVasive™ Triad™ Facet Screw System is a surgical implant designed to stabilize the spine. It is physically inserted into the body.
- Intended Use: The intended use is to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints. This is a surgical procedure, not a diagnostic test performed on a specimen.
The information provided clearly describes a surgical implant used for spinal fusion, which falls under the category of medical devices, but not specifically In Vitro Diagnostic devices.
N/A
Intended Use / Indications for Use
The NuVasive™ Triad™ Facet Screw System is intended to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints. The screws are inserted posteriorly through the superior side of the facet, across the facet joint, and into the pedicle. The NuVasive™ Triad™ Facet Screw System is indicated for bilateral facet fixation, with or without bone graft, at single or multiple levels, from C2 to S1 for the 3.5mm screws, and from L1 to S1 for the 4.5mm screws. The Triad™ Facet Screw System is indicated for treatment of any or all of the following:
- (a) pseudoarthrosis and failed previous fusion;
- (b) spondylolisthesis;
- (c) spondylolysis;
- (d) degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by radiographic studies;
- (e) degeneration of the facets with instability; and
- (i) fracture.
The NuVasive™ Triad™ Facet Screw System is intended for conventional or percutaneous surgical placement.

Device Description
The NuVasive™ Triad™ Facet Screw System consists of broad-headed, partially threaded screws designed to compact juxtaposed facet articular processes to enhance spinal fusion The non-threaded portion facilitates compression of the joint surfaces and stability. through a lag technique. Washers may be used to complement the screws by helping distribute forces and maintain consistent contact area when the screws are angled relative to the bone surface. The screws and washers are fabricated from anodized titanium alloy (Ti-6Al-4V) and are supplied in various sizes.
