Intended Use

The Akros Scruture Anchor LisFranc Repair Kit is intended as an adjunct in fracture repair involving metaphyseal and periarticular small bone fragments where screws are not indicated, and as an adjunct in external fixation systems involving plates, with fracture braces and casting. Specifically, the Akros Scruture Anchor LisFranc Repair Kit is intended to provide fixation during the healing process following Tarasometatarsal (TMT) injury, such as fixation of foot soft tissue separations due to a Lisfranc injury (Midfoot Reconstruction).

Device Story

Multiple-anchor orthopedic fixation system; stainless steel or titanium versions; used for midfoot fixation during Lisfranc injury healing. Implant design allows placement through fracture repair plates accepting 4.0mm cortical screws. Kit includes pre-threaded/pre-loaded anchors on installation tools, Kirschner wire, and drill bit. Used by surgeons in clinical settings to provide bone fixation; acts as adjunct to plates, braces, or casting. Benefits patient by stabilizing unstable joints during healing process.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing including lateral pull-to-failure, simulated use, offset load-to-failure, insertion torque, torque-to-failure, fatigue, fretting, corrosion, MRI compatibility, and biocompatibility (cytotoxicity, pyrogenicity). Bacterial endotoxin testing performed on reference device.

Technological Characteristics

Multiple-anchor fixation system; stainless steel or titanium; compatible with 4.0mm cortical screws per ASTM F543-13. Pre-sterilized, single-use kit. Mechanical fixation principle.

Indications for Use

Indicated for patients requiring fixation during the healing process following Tarasometatarsal (TMT) injury, specifically foot soft tissue separations due to Lisfranc injury (midfoot reconstruction), and as an adjunct in fracture repair of metaphyseal and periarticular small bone fragments where screws are not indicated.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Mr. Horrell:

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 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

## Device Description:

The Akros Scruture Anchor Lisfranc Repair Kit is a multiple-anchor orthopedic fixation device system, offered in both a stainless steel and a titanium version. The system is designed as an adjunct in repair of unstable joints, specifically as a means to provide fixation between the bones of the midfoot during the healing process following a Lisfranc injury. The design of the implant permits placement through any fracture repair plate that can accept a 4.0mm cortical screw conforming to ASTM F543-13. The anchors are provided pre-threaded and pre-loaded on their installation tools in a one-time-use pre-sterilized kit, with the Kirschner wire and drill bit needed for site preparation included.

#### Intended Use / Indications:

The Akros Scruture Anchor LisFranc Repair Kit is intended as an adjunct in fracture repair involving metaphyseal and periarticular small bone fragments where screws are not indicated, and as an adjunct in external fixation systems involving plates, with fracture braces and casting. Specifically, the Akros Scruture Anchor LisFranc Repair Kit is intended to provide fixation during the healing process following Tarasometatarsal (TMT) injury, such as fixation of foot soft tissue separations due to a LisFranc injury (Midfoot Reconstruction).

#### Summary of Technologies/Substantial Equivalence:

The Akros Scruture Anchor Lisfranc Repair Kit is substantially equivalent to the predicate device in terms of its intended use and indications, materials, basic design and mechanical performance. Any noted differences do not raise new types of safety and effectiveness questions, nor are there new technological issues.

#### Non-Clinical Testing:

Lateral pull-to-failure testing was conducted. Data from simulated use, offset load-to-failure, insertion torque, torque-to-failure, fatigue with pull-to-failure, fretting, pitting corrosion, magnetic resonance, cytotoxicity, and pyrogenicity testing were adopted from the reference device (the Akros FibuLink Syndesmosis Repair System) given the similarity of its design and manufacture. The results of these tests indicate that the performance of the Scruture Anchor device is adequate for its intended use.

Bacterial Endotoxin Testing was performed on the reference device, which is considered worst case, using the Limulus Amebocyte Lysate (LAL) test. Results demonstrated that the reference device meets an endotoxin limit of <20 EU/device.

#### Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the Akros Scruture Anchor Lisfranc Repair Kit to the predicate device.
