The description focuses on the mechanical design and materials of a bone screw system, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes.
The device is intended for the fixation of fractures, non-union, and osteotomies, which are medical conditions, and its purpose is to treat these conditions by providing stability and promoting healing.
No
The device is described as a screw system intended for fixation of intra-articular fractures, non-union, and osteotomies, which indicates it is a therapeutic or restorative device, not one used for diagnosis.
No
The device description clearly describes a physical implant (screws) made of Titanium Alloy, which is a hardware component. The summary also details performance studies related to the mechanical properties of these screws.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description: The MINIARS screw system is described as an implantable device made of titanium alloy, intended for the fixation of bones and bone fragments. It is surgically implanted into the body.
- Intended Use: The intended use clearly states it's for "fixation of intra-articular fractures, non-union and osteotomies of small bones and small bone fragments." This is a surgical procedure, not an in vitro diagnostic test.
The device is a surgical implant, not a device used to test samples outside of the body.

Device Description
The following is a brief description of the Overmed MINIARS Screws.
MINIARS screw system is intended for fixation of intra-articular and extra-articular fractures, non-union and osteotomies of small bones and small bone fragments.
MINIARS screws are implants that will be in contact with body tissues for more than 30 days. Instrumentation used to assist in their implantation will be in temporary contact (inferior to 24 hours) with body tissues.
The MINIARS screws are intended for single use only.
The implant is a solid, one piece, cannulated and partially thread shaped design.
MINIARS screws are available in two different external thread diameters: 2.2 mm e 2.6 mm.
MINIARS screws are available in a range of lengths from 10mm to 30mm.
The screws are partially threaded: the proximal and distal parts are threaded while the middle part is cylindrical, as visible in figure 5.1.
The thread shape has been designed to facilitate the compression of the bone fragments and the hold in cancellous bone thanks to the particular profile design: the wide thread pitch of the distal part penetrates in bone tissue faster than the thread of the proximal part, reducing and compressing the fracture through screw advance.
Distal thread presents self-drilled and self-tapping grooves.
The screws present a hexagonal torx 6 head which is conforming to ISO 10664 standard.
All the MINIARS screws are supplied in a sterile state (beta rays); the single screw is packed into a double blister which allows the usage in surgery.
The MINIARS Screws are made of Titanium Alloy (Ti6A14V ELI gr. 5) and is available in the range of sizes reported in the table below.

Summary of Performance Studies
To support the performance characteristics of MINIARS screws we conducted the following tests:
- FEA analysis, to study the maximum stress in the subject screw under a 300Ncm torsional load;
- Pullout test, to measure the strength to be employed in order to extract a screw . totally inserted into the bone;
- Maximum screw torque test, to measure the maximum torque bearable before the ● screw failure;
- Bending test, to measure the vield moment reached after a 2.5 mm displacement. ●
- . Dimensional comparison with other 510(k) cannulated screws
The results demonstrated that the performance of the subject device is substantially equivalent to the predicate 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)
Classification. Class II.

5.2 Description:
The following is a brief description of the Overmed MINIARS Screws.
MINIARS screw system is intended for fixation of intra-articular and extra-articular fractures, non-union and osteotomies of small bones and small bone fragments.
MINIARS screws are implants that will be in contact with body tissues for more than 30 days. Instrumentation used to assist in their implantation will be in temporary contact (inferior to 24 hours) with body tissues.
The MINIARS screws are intended for single use only.
The implant is a solid, one piece, cannulated and partially thread shaped design.
MINIARS screws are available in two different external thread diameters: 2.2 mm e 2.6 mm.
MINIARS screws are available in a range of lengths from 10mm to 30mm.
All the screws sizes available are described in table 5.1.
The screws are partially threaded: the proximal and distal parts are threaded while the middle part is cylindrical, as visible in figure 5.1.
The thread shape has been designed to facilitate the compression of the bone fragments and the hold in cancellous bone thanks to the particular profile design: the wide thread pitch of the distal part penetrates in bone tissue faster than the thread of the proximal part, reducing and compressing the fracture through screw advance.
Distal thread presents self-drilled and self-tapping grooves.
Image /page/4/Picture/12 description: The image shows a long, silver-colored medical screw. The screw has threads on both ends and a smooth, cylindrical shaft in the middle. The threads appear to be designed for bone fixation, and the screw is likely used in orthopedic surgery to stabilize bone fractures or joints.
Fig. 5.1 MINIARS Screw
The screws present a hexagonal torx 6 head which is conforming to ISO 10664 standard.
All the MINIARS screws are supplied in a sterile state (beta rays); the single screw is packed into a double blister which allows the usage in surgery.

- Maximum screw torque test, to measure the maximum torque bearable before the ● screw failure;
- Bending test, to measure the vield moment reached after a 2.5 mm displacement. ●
- . Dimensional comparison with other 510(k) cannulated screws
The results demonstrated that the performance of the subject device is substantially equivalent to the predicate devices.
5.5 Substantial equivalence:
Documentation is provided which demonstrates the Overmed MINIARS Screws to be substantially equivalent to other legally marketed devices. All the devices are "Smooth or threaded metallic bone fixation fastener" as defined in 21 CFR 888.3040, furthermore, the size, shape and materials for the subject devices are comparable to the predicate devices.
5.6 Conclusion:
Based upon the similarities in design, materials, performance testing and intended uses, the Overmed MINIARS Screw is substantially equivalent to the predicate devices.
