The summary describes a mechanical screw for bone fixation and does not mention any software, algorithms, or AI/ML capabilities.
No
The device is a compression screw used for fracture fixation and bone reconstruction, not for therapy or treatment of diseases.
No
Explanation: The device, Merete Compression Screws, is used for fracture fixation and reconstruction of bones. This is a therapeutic function rather than a diagnostic one.
No
The device description clearly states that the device is a physical screw made of Titanium alloy, which is a hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This includes tests for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The description clearly states that the Merete Compression Screws are used for fracture fixation and reconstruction of bones. This is a surgical implant used directly within the body to provide structural support.
- Lack of IVD Characteristics: There is no mention of analyzing biological specimens, performing tests on samples, or providing diagnostic information based on laboratory analysis.
Therefore, the Merete Compression Screws fall under the category of a surgical implant or orthopedic device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
Merete Compression Screws are indicated for fracture fixation and reconstruction of various bones, including
- osteotomies in the foot (as Hallux Valgus treatment) or hand, -
- arthrodesis in hand, foot or ankle surgery, 1
- fixation of bone fragments in long bones or small bone fractures. -
The size of the chosen screw should be adapted to the specific indication.

§ 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.

Predicate Device:
Screws 3.0 mm and 4.3 mm: K050346 NewDeal Stabilization Screw
Screw 6.5 mm: K991151 Vilex/Duval/Orthex Cannulated Bone Screw
Substancial Equivalence:
Merete Compression Screws are similar to legally marketed predicate device listed above in that they share similar indications for use, are manufactured from similar materials and incorporate similar technological characteristics.

2 Bending Strength Rationale
The referenced predicate devices in K050346 and K991151 are similar in their dimensions to the Merete Compression Screws 3.0, 4.3 and 6.5 mm as they present a similar core diameter, thread diameter as well as a similar cannulation.
As the predicate devices are manufactured from similar materials (Ti-6Al-4V) too, the bending strength of the Merete Compression Screws 3.0, 4.3 and 6.5 mm can be supposed as similar as well.

Dear Mr. Mietzner:
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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
