Intended Use
InFix Cannulated Screw System is generally intended for fracture fixation of various bones and bone fragments, such as femoral neck, intercondylar femoral, malleolus, pilon tibial, calcaneus, talus, tibial plateau, tarsal, wrist, metacarpal, carpal, scaphoid and radius fracture. InFix Cannulated Screw System is also intended for fixation arthrodesis, iliosacral dislocations, and hallux valgus corrections. Accessories implants: The round washer is used to increase bone contact area for distributing the forces/load and prevent the screw head from sinking into the bone.
Device Description
The InFix Cannulated Screw System includes eight cannulated screw specifications and associated washers, which are manufactured from stainless steel and titanium alloy. The cannulated screw is a self-tapping and self-drilling screw with a cancellous thread that can be guided into a position via a guided wire. They are used to aid in the alignment and stabilization of fractures to the skeletal system.
More Information

No
The device description and performance studies focus on the mechanical properties and sterilization of the screws, with no mention of AI or ML.

Yes
The device is intended for fracture fixation and arthrodesis, which are medical treatments for conditions.

No

The device is a system of cannulated screws intended for fracture fixation and arthrodesis, which are treatments for existing conditions, not diagnostic procedures.

No

The device description explicitly states that the InFix Cannulated Screw System includes physical components (screws and washers) made of stainless steel and titanium alloy, which are hardware.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the device is for "fracture fixation of various bones and bone fragments" and "fixation arthrodesis, iliosacral dislocations, and hallux valgus corrections." This describes a surgical implant used to treat musculoskeletal conditions.
  • Device Description: The description details a "cannulated screw system" made of stainless steel and titanium alloy, designed to be guided into position via a guide wire for "alignment and stabilization of fractures to the skeletal system." This is consistent with a surgical implant.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment. IVDs are typically used in laboratories or point-of-care settings for diagnostic purposes.

Therefore, the InFix Cannulated Screw System is a surgical implant, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-Clinical Tests
Biomechanical Test
The biomechanical tests ASTM F543 were performed to determine substantial equivalence of the InFix Cannulated Screw System including self-tapping, torsional, axial pullout and driving torque. Results indicate that the subject screws are substantially equivalent to legally marketed devices offering a reasonable assurance of safety and effectiveness.

Cleaning Validation
The cleaning validation was performed in according with the AAMI TIR30:2011 guidance document. The test result shows that the acceptance criteria is met.

Sterilization Validation
The sterilization validation was performed in according with the ANSI/AAMI/ISO 17665-1. The test result shows that the acceptance criteria is met.

The InFix Cannulated Screw System has not been evaluated for safety and compatibility in the MR environment. It has not been tested for heating, migration, or image artifact in the MR environment. The safety of the InFix Cannulated Screw System in the MR environment is unknown. Scanning a patient who has this device may result in patient injury.

Clinical Tests
Clinical data and conclusions were not needed for these devices to show substantial equivalence.

§ 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.
