Intended Use

The Medline UNITE® Digital Fusion Screws are indicated for use in bone reconstruction, osteotomies, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the device including corrective procedures for hammertoe, mallet toe, and claw toe deformities. Screws are intended for single use only.

Device Story

Medline UNITE® Digital Fusion Screw System consists of titanium alloy bone fixation screws; 2.3mm diameter; 20-55mm lengths; low-profile headed and headless designs. Screws are self-drilling and self-tapping. Used by surgeons for bone reconstruction, osteotomies, arthrodesis, joint fusion, and fracture repair/fixation, specifically for toe deformities (hammertoe, mallet toe, claw toe). Device provides mechanical stabilization of bone segments to facilitate healing. Single-use only.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated via non-clinical bench testing comparing shear failure force and torsional yield strength to the predicate device.

Technological Characteristics

Titanium alloy bone fixation screws; 2.3mm diameter; 20-55mm lengths; self-drilling and self-tapping; low-profile headed and headless configurations. Non-sterile. Mechanical fixation device.

Indications for Use

Indicated for bone reconstruction, osteotomies, arthrodesis, joint fusion, fracture repair, and fixation in patients requiring corrective procedures for hammertoe, mallet toe, and claw toe deformities. Intended for single use.

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.

Predicate Devices

• Medline Cannulated Screws (K130319)
• PRO-TOE VO Hammertoe Implant System (K101165)

#### Dear Jennifer Mason:

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.

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

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

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).

from 20mm up to 55mm in 5mm increments. The screws feature low profile headed and headless screws. The screws are self-drilling and self-tapping.

#### Indications for Use

The Medline UNITE® Digital Fusion Screws are indicated for use in bone reconstruction, osteotomies, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the size of the device including corrective procedures for hammertoe, mallet toe, and claw toe deformities. Screws are intended for single use only.

#### Summary of Technological Characteristics

The proposed modified device is substantially equivalent to the primary predicate, Medline Cannulated Screws. A discussion of similarities and differences is listed below.

- o Intended use - identical.
- Indications for Use - similar. The indication for use for the Medline UNITE® Digital Fusion Screws are more specific than the predicate but still fall under the same intended use.
- Materials - identical. Both the proposed and predicate device are made from the same material, titanium alloy.
- Sizes - similar. The Medline UNITE Digital Fusion Screws will be offered in a 2.3mm diameter in leneths from 20 – 55mm. The predicate device has diameters ranging from 2.0 to 7.5mm with lengths ranging from 10 - 130mm. The diameters and lengths of the Medline UNITE® Digital Fusion Screws are within the diameters and lengths of the previously cleared Medline Cannulated Screws.

#### Summary of Non-Clinical Testing

The subject device, Medline UNITE® Digital Fusion Screws, do not represent a new worst-case when compared to the previously cleared Medline Cannulated Screws (K130319). However, analysis was conducted to further demonstrate substantial equivalence of the Medline UNITE® Digital Fusion Screws to the predicate. Medline Cannulated Screws. Based on this analysis, the subject device, Medline UNITE® Digital Fusion Screws, are substantially equivalent to the predicate, Medline Cannulated Screws, in predicted shear failure force (axial pullout force) and torsional yield strength.

# Summary of Clinical Testing

Not applicable.
