Intended Use

The Nextremity Solutions Nextra PEEK Hammertoe Correction System is indicated for small bone reconstruction limited to inter-phalangeal repair and fusion of the lesser toes.

Device Story

The Nextra PEEK Hammertoe Correction System is a two-part mating bone screw implant construct designed for inter-phalangeal repair and fusion of lesser toes. The system includes proximal and middle screw implants available in various diameters and angles (0° and 10°). It is used by orthopedic surgeons in a clinical or surgical setting to stabilize small bones during fusion procedures. The device is provided sterile for single use and includes specific drivers, taps, and surgical site preparation instruments. By providing mechanical fixation, the system facilitates bone fusion, potentially reducing pain and correcting toe deformities.

Clinical Evidence

No clinical data. Substantial equivalence was demonstrated through non-clinical bench testing, including static and dynamic 3-point bend testing per ASTM F2193-18a and endotoxin testing per AAMI ST72, USP 161, and USP 85.

Technological Characteristics

Two-part mating bone screw implant construct. Materials: Polyetheretherketone (PEEK) conforming to ASTM F2026. Dimensions: Proximal screws (3.2mm, 4.2mm diameter); Middle screws (3.5mm, 4.25mm, 5.0mm diameter, 0°/10° angles). Mechanical testing: Static and dynamic 3-point bend tests per ASTM F2193-18a. Sterilization: Provided sterile for single use.

Indications for Use

Indicated for small bone reconstruction, specifically inter-phalangeal repair and fusion of the lesser toes in patients requiring such orthopedic intervention.

Regulatory Classification

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.

Dear Elise Fox:

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.

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.

{1}------------------------------------------------

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 803) for devices or postmarketing safety reporting (21 CFR 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 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

## Summary of Technologies/Substantial Equivalence:

The Nextra PEEK Hammertoe Correction System is substantially equivalent to the predicate devices regarding the intended use and indications, material, design, sizes, and mechanical properties. Differences between the subject device system and the predicate device systems do not raise new types of safety and effectiveness questions.

#### Non-Clinical Testing:

Endotoxin testing was performed using the Limulus Amebocyte Lysate (LAL) method according to AAMI ST72, USP 161 and USP 85. Results met the Endotoxin limit of ≤20 EU per device. To evaluate the strength of the Nextra PEEK Hammertoe Correction System and components, static 3-point bend tests and dynamic 3-point bend tests were performed on the worst case implant construct according to ASTM F2193-18a. These tests confirmed that the strength of the Nextra PEEK Hammertoe Correction System is substantially equivalent to predicate devices with similar indications and is adequate for its intended use.

### Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the Nextra PEEK Hammertoe Correction System to the predicate device.

### Conclusions/Substantial Equivalence:

The Nextra PEEK Hammertoe Correction System is substantially equivalent to the predicate devices regarding its intended use, material, design, sizes, and mechanical properties. Differences between the subject device system and the predicate device systems do not raise new types of safety and effectiveness questions.
