The summary describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is used to treat various spinal conditions such as fractures, deformities, and spondylolisthesis, which aims to improve the patient's health and alleviate their conditions.
No
The device is described as an implantable system for spinal fixation, used to treat various spinal conditions. Its function is to create a rigid spinal construct and facilitate surgical procedures, not to diagnose conditions.
No
The device description explicitly states it is comprised of "implantable components" manufactured from titanium alloy, indicating it is a hardware 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 tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description and Intended Use: The description clearly states that the ZODIAC Polyaxial Pedicle Screw System is comprised of implantable components (screws, hooks, rods) made of titanium alloy. Its intended use is for surgical fixation of the spine in patients with various conditions like fractures, deformities, and spondylolisthesis.
- Lack of Diagnostic Activity: There is no mention of this device being used to analyze biological samples or provide diagnostic information. It is a physical implant used for structural support and stabilization.
Therefore, this device falls under the category of a surgical implant or spinal fixation system, not an in vitro diagnostic device.

§ 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.

Dear Ms. Yarnell:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
