The device description focuses on mechanical components (plates, screws, instruments) and a surgical procedure. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance study is a mechanical FEA analysis, not a study of algorithmic performance.
Yes
The device is used for anterior screw fixation of the cervical spine to treat various spinal conditions, which qualifies it as a therapeutic intervention.
No
The provided text describes a medical device, the BLACKSTONE MEDICAL, INC. Anterior Cervical Plate System, which is used for anterior screw fixation of the cervical spine. Its purpose is to physically stabilize the spine, not to detect, monitor, or diagnose medical conditions. The indications for its use are conditions like Degenerative Disc Disease, Spondylolisthesis, Fracture, etc., but the device itself is a treatment, not a diagnostic tool.
No
The device description clearly outlines physical components made of titanium (plates, screws, locking plate) and surgical instruments, indicating it is a hardware-based medical device.
No, 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, tissue) to provide information about a person's health. These tests are performed outside of the body.
- Device Description: The description clearly states that this is a system of plates, screws, and instruments used for anterior screw fixation of the cervical spine. This is a surgical implant and associated tools used within the body during a surgical procedure.
- Intended Use: The intended use is for surgical stabilization of the cervical spine for various conditions. This is a therapeutic intervention, not a diagnostic test.
Therefore, based on the provided information, the BLACKSTONE MEDICAL, INC. Anterior Cervical Plate System is a surgical implant and instrument system, not an In Vitro Diagnostic device.

Device Description
The principal components of the Blackstone Medical Inc. Anterior Cervical Plate System are plates, screws, and locking plate made from titanium 6Al-4V Eli alloy, as per ASTM F-136. The instrument set includes 6 Degree/15 Degree Plate Holder and Guide 6 Degree/0 Degree Plate Holder and Guide Freehand Guide Drill with Adjustable Stop Bone Tap with Adjustable Stop Bone Screw Driver Lock Plate Screw Driver Plate Bender Tack and Tack Holder After determining the appropriate plate length, the plate is positioned on the anterior surface of the cervical spine. The cannula is seated into the plate at the correct cranial /caudal and convergent angle. Once the drill bit has been placed in the cannula and drilled, the tap is inserted into the cannula, the vertebral bodies are tapped and the screws are inserted. The screws are then tightened to ensure that they are seated below the surface of the plate. The cannula is removed. The lock plate is positioned over the bone screws and secured with lock plate screw driver. The components of the Blackstone Medical Inc. Anterior Cervical Plate System are manufactured from titanium 6Al-4V Eli alloy, as described by ASTM F-136.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Blackstone Cervical Plate was compared to a Synthes Performance Cervical Plate per FEA analysis to determine the difference in stiffness and stress. The plates were similar in length. The Blackstone Plate was 288% stiffer than the Synthes Plate and the maximum stress associated with the Blackstone Plate was 41% less than the Synthes Plate.

§ 888.3060 Spinal intervertebral body fixation orthosis.
(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.

Re: K974885 Anterior Cervical Plate System Regulatory Class: II Product Code: KWQ Dated: April 9, 1998 Received: April 10, 1998
Dear Mr. Lyons:
We have reviewed your Section 510(k) notification of intent to market the device system referenced above and we have determined the device system is substantially equivalent (for the indications for use stated in the enclosure) to device systems marketed in interstate commerce prior to May 28, 1976 or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) . . You may, therefore, market your device system subject to the general controls provisions of the Act and the limitations identified below.
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. Note that labelinq or otherwise promotinq this device system for pedicular screw fixation/attachment would cause the device system to be adulterated under 501(f) (1) of the Act.
FDA identifies that any device system, if intended for use in pedicular screw fixation/attachment, except for some limited indications, would be found not substantially equivalent and would be 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:
- You may not label or in any way promote this device 1. system for pedicular screw attachment to, or fixation of the cervical, thoracic or lumbar vertebral column. Therefore, in order to prevent off-label promotion, the package insert must include the following statement,
3
"WARNING : This device system is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.";
- All labeling for this device system, including the 2. package label, must state that there are labeling limitations. The package insert must prominently state that the device system is intended for the specific use(s) described in the enclosure only; and
-
- Pedicular screw fixation/attachment to the cervical, thoracic or lumbar vertebral column, except for limited indications, of any device system 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 system for pedicular screw fixation/attachment must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) prior to conducting an investigation.
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 Requlations, Title 21, Parts 800 to 895. ਰੇ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Druq Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Reqister. 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.
FDA advises that the use of the subject device system and/or device components with any other device components but those identified in this 510(k) would require submission of a new 510(k) providing d cumentation 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 other manufacturers', may also be required.
