The summary describes a system of mechanical implants for spinal fixation and does not mention any software, algorithms, or AI/ML capabilities.
Yes.
The device is intended to treat and provide stabilization for various medical conditions, including spinal pain, instability, and trauma, which aligns with the definition of a therapeutic device.
No
The document describes the CerviFix® System as a set of implants (rods, plates, hooks, screws, etc.) intended for stabilization and to promote fusion in the cervical/upper thoracic spine following various conditions or trauma. It does not mention any function related to diagnosing conditions or providing diagnostic information.
No
The device description explicitly lists physical components made of Titanium or titanium alloy (rods, plate/rods, hooks, clamps, screws, nuts, transconnectors). This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The description clearly states that the CerviFix® System consists of implants (rods, plates, hooks, screws, etc.) made of titanium or titanium alloy. These are physical devices intended to be surgically implanted in the body.
- Intended Use: The intended use describes the surgical conditions the device is used to treat (DDD, spondylolisthesis, spinal stenosis, fracture/dislocation, etc.) and the anatomical locations where it is implanted (cervical/upper thoracic spine, occipital). This is a description of a surgical implant, not a diagnostic test performed on a sample.
Therefore, the CerviFix® System is a surgical implant, not an in vitro diagnostic device.

Intended Use / Indications for Use
The CerviFix® System is indicated for the following:
- DDD (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiographic studies
- Spondylolisthesis ●
- Spinal stenosis ●
- Fracture/dislocation ●
- Atlantoaxial fracture with instability ●
- Occipitocervical dislocation ●
- Revision of previous cervical spine surgery ●
- Tumors ●
When used to treat these cervical and occipitocervical conditions, these screws are limited to occipital fixation only.
Hooks and Rods
The rod and hook components are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine.
Rods, Clamps, Screws and Nuts
The rods, clamps, screws and nuts are intended to promote fusion following reduction of fracture/dislocation or trauma in the upper thoracic spine (T1-T3).
The use of these screws (3.5 mm, 4.0 mm cancellous and 3.5 mm, 4.2 mm cortex) is limited to placement in T1-T3 in treating thoracic conditions only. They are not intended to be placed in or treat conditions involving the cervical spine.

§ 888.3050 Spinal interlaminal fixation orthosis.
(a)
Identification. A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.(b)
Classification. Class II.
