The summary describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is described as a 'spinal system' used for 'pedicle screw fixation' and 'non-pedicle screw fixation' to provide 'stabilization during the development of a solid spinal fusion' for various spinal conditions like degenerative disc disease, spondylolisthesis, spinal stenosis, spinal deformities, fracture, pseudarthrosis, and tumor resection. These are all conditions that require medical intervention to alleviate symptoms, correct a defect, or restore function, thus classifying it as a therapeutic device.
No
The device is a spinal fixation system, used for stabilization during spinal fusion, not for diagnosing medical conditions.
No
The device description explicitly lists physical components like rods, hooks, screws, and connectors, indicating it is a hardware-based medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Description and Intended Use: The description and intended use clearly state that the CD Spinal System is a spinal implant used for fixation and stabilization of the spine during fusion procedures. It is a physical device implanted into the body.
- Lack of Specimen Handling: There is no mention of the device being used to collect, prepare, or examine any specimens from the human body.
- Anatomical Site: The anatomical sites mentioned (spine, L5-S1, etc.) are locations within the body where the device is implanted, not where specimens are collected.
Therefore, the CD Spinal System falls under the category of a surgical implant or orthopedic device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
When used as a pedicle screw fixation system with CD screws attached to the non-cervical posterior spine, the CD Spinal System is indicated for degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies).
When used as a pedicle screw fixation system, the CD Spinal System is also indicated for Grade III and IV spondylolisthesis. For this indication only, the spondylolisthesis must be at L5-S1 in patients who are receiving fusions using autogenous bone graft only and who are having the device removed after the development of a solid fusion mass. Although the levels of fusion may not go above the L5-S1 joint for these severe spondylolisthesis cases, the levels of pedicle screw fixation may be L3 to the sacrum.
When used as a posterior non-pedicle screw fixation system, the CD Spinal System is intended for the indications given above as well as spinal stenosis, spondylolisthesis, spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis), fracture, pseudarthrosis, tumor resection, and unsuccessful previous attempts at spinal fusion. For non-pedicle screw use, the levels of fixation for the CD Spinal System are T1 to sacrum, with the screws limited to sacral fixation.

§ 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.

You may, therefore, market your device system subject to the general controls provisions of the Act and the limitations The general controls provisions of the Act identified below. include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions aqainst misbranding and adulteration. Note that labeling or otherwise promoting this device system for pedicular screw fixation/attachment for indications other than that described in item 2 below, would cause the device system to be adulterated under 501(f)(1) of the Act.
This device system, when intended for pedicular screw fixation/attachment to the spine for indications other than that described in item 2 below, is a class III device under Section 513(f) of the Act. Class III devices are required to have an approved premarket approval (PMA) application prior to marketing. Accordingly:
The package label, must state that there are labeling 1. limitations.

See Warnings, Precautions, and Potential Adverse Events sections of the package insert for a complete list of potential risks.
- Any pedicular screw fixation/attachment for intended uses 4 . other than that described by item 2 above, for this device is considered investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulations under 21 CFR, Part 812. All users of the device for pedicular screw fixation/attachment for intended uses other than that described above, must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) prior to conducting an investigation.
-
- Any previous warning statements identified as part of previous 510(k) clearances or required by OC/Labeling and Promotion which stated that a component/system was not approved for screw fixation into the pedicles of the spine must be replaced by the warnings of item 3 above.
FDA advises that the use of your device system with any other device components but those identified in this 510(k) would require submission of a new 510(k) providing documentation of design, material, and labeling compatibility between the device components. Mechanical testing of a spinal system consisting of the subject device components and other device components, whether yours or those of other manufacturers, may also be required.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), 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 895. ਸ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
