The device description and performance studies focus on the mechanical properties and biocompatibility of the screws and instruments, with no mention of AI or ML.
Yes.
The device is intended for "fixation of sacroiliac joint disruptions, and intended for sacrolliac joint fusion for conditions including; - sacroiliac joint disruptions - degenerative sacroiliitis - to augment immobilization and stabilization of the sacrolliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar of thoracolumbar fusion and - acute, non-acute and non-traumatic fractures involving the sacroiliac joint." These are all therapeutic actions aimed at treating patient conditions.
No
Explanation: The device is a surgical implant (fusion system) intended for fixation and fusion of the sacroiliac joint, not for diagnosing medical conditions.
No
The device description explicitly states that the system includes "cannulated, 3D printed, titanium alloy bone screws as well as a full complement of instruments to place them in the body," 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:
- Intended Use: The intended use clearly states the device is for "fixation of sacroiliac joint disruptions" and "sacroiliac joint fusion." This describes a surgical procedure performed directly on the patient's body.
- Device Description: The device is described as "cannulated, 3D printed, titanium alloy bone screws" and instruments for placing them "in the body." This is a description of an implantable surgical device.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections. This device does not perform any such testing.
The T-FIX® 3DSI Joint Fusion System is a surgical implant used to stabilize and fuse the sacroiliac joint.

Device Description
The T-FIX® 3DSI Joint Fusion System, a line extension of the EVOL® -SI Fusion System (K190025), is intended to treat dysfunctions of the sacroiliac joint. The subject T-FIX® 3DSI Joint Fusion System includes cannulated, 3D printed, titanium alloy bone screws as well as a full complement of instruments to place them in the body. The subject T-FIX® screw is headless so that it may be implanted with a zero profile. The distal portion of the screw has a single lead thread and the proximal end has a double lead thread. The subject T-FIX® is designed to cross the sacroiliac joint anchoring the sacrum to the pelvis thereby preventing motion of the sacroiliac joint. The subject T-FIX® screws are made from a titanium alloy Ti-6A1-4V Grade 23 per ASTM 3001 and offered with a HA nano surface treatment.

Summary of Performance Studies
Mechanical Testing: Testing was performed for the T-FIX® 3DSI Joint Fusion System and demonstrated substantial equivalent performance to the identified predicates. The mechanical tests were performed in accordance to these test methods: Static cantilever bending, Axial Pullout, Torque to Failure, and Dynamic cantilever bending - ASTM F543 - ASTM F2193. In all, the biomechanical testing results demonstrate that the T-FIX® 3DSI Joint Fusion System is substantially equivalent to the predicate device. Non-Pyrogenicity Endotoxin Testing: The bacterial endotoxin test, also known as Limulus Amebocyte Lysate (LAL) on the worst case subject EVOL® -SI Joint Fusion System implants verify that the subject implants (line extension T-FIX® 3DSI) meet the 20 endotoxin units (EU)/device pyrogen limit specification, as outlined in ANSI/AAMI ST72, Bacterial endotoxins - Test methods, routine monitoring, and alternatives to batch testing and USP , Transfusion and Infusion Assemblies and Similar Medical Devices.

§ 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)

Dear Kyle Kuntz:
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. 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 located 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.

Non-Pyrogenicity Endotoxin Testing
The bacterial endotoxin test, also known as Limulus Amebocyte Lysate (LAL) on the worst case subject EVOL® -SI Joint Fusion System implants verify that the subject implants (line extension T-FIX® 3DSI) meet the 20 endotoxin units (EU)/device pyrogen limit specification, as outlined in ANSI/AAMI ST72, Bacterial endotoxins - Test methods, routine monitoring, and alternatives to batch testing and USP , Transfusion and Infusion Assemblies and Similar Medical Devices.
CONCLUSIONS VIII.
Based upon a comparison of technological characteristics, intended use, design features, and mechanical performance, the T-FIX® 3DSI Joint Fusion System does not raise any new safety or efficacy concerns and has demonstrated substantial equivalence to the identified predicates.
