No
The document describes a mechanical implant system for sacroiliac joint fusion and pelvic fracture fixation. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is intended for sacroiliac joint fusion and fracture fixation, indicating its use in treating medical conditions or injuries.
No
The device is described as an implant system (screws) for sacroiliac joint fusion and fracture fixation, which is a therapeutic intervention, not a diagnostic one.
No
The device description explicitly states it consists of "threaded, fenestrated, cannulated, 3D-printed implants and associated instruments," which are physical hardware components.
Based on the provided text, the DYNAMIS™ SI Screw System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- DYNAMIS™ SI Screw System Function: The description clearly states that the DYNAMIS™ SI Screw System is a system of implants and instruments used for surgical fixation and fusion of the sacroiliac joint and pelvis. It is a physical implant placed within the body.
- Lack of IVD Characteristics: The text does not mention any analysis of biological specimens, diagnostic testing, or any function related to providing information from the body for diagnostic purposes.
Therefore, the DYNAMIS™ SI Screw System falls under the category of a surgical implant/device rather than an In Vitro Diagnostic device.

Intended Use / Indications for Use
The DYNAMIS™ SI Screw System is indicated for sacroiliac joint fusion for:
· Sacroiliac joint dysfunction including sacroiliac joint disruption and degenerative sacroillitis.
· Augmenting immobilization and stabilization of the sacroiliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion.
The DYNAMIS™ SI Screw System is also indicated for fracture fixation of the pelvis, including acute, non-acute and nontraumatic fractures.

Device Description
The DYNAMIS™ SI Screw System consists of threaded, fenestrated, cannulated, 3D-printed implants and associated instruments. Implants are constructed from medical grade titanium alloy (Ti-6Al-4V ELI per ASTM F3001). The implants are fully threaded with a lag design. To accommodate varying patient anatomy, the DYNAMIS™ SI Screw Implants are available in multiple diameters and length offerings. The DYNAMIS™ SI Screw Implants consist of a cannulated central threaded body. The implants allow for packing of autograft and allograft materials. Using the designated instrument system, two or more implants should be inserted across the SI Joint to apply a compressive force across the joint and to provide stabilization and fusion. The DYNAMIS™ SI Screw implants are single use devices that are provided sterile.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Dear Glenn Bowman:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review. the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
