Intended Use

The AlignX Ankle Fusion System is intended to facilitate arthrodesis of the ankle including tibiotalocalcaneal and tibiotalar joints.

Device Story

The AlignX Ankle Fusion System is a bone fixation device used by orthopedic surgeons to facilitate ankle arthrodesis. The system consists of anatomical anterior and lateral tibia plates, locking and non-locking screws, and associated surgical instruments for site preparation and delivery. The anterior plates feature a central hole for a 'home run' screw to provide axial compression across the tibiotalar (TT) or tibiotalocalcaneal (TTC) joints; the 2-tab plate includes an anterior window for autologous bone grafting and fluoroscopic visualization of fusion. The lateral plates are configured for either TT or TTC fusion. The device is used in an operating room setting. By providing rigid fixation and compression, the system stabilizes the joint to promote bone fusion, potentially reducing pain and improving joint function for the patient.

Clinical Evidence

No clinical testing was performed. Substantial equivalence is supported by engineering analysis and mechanical testing.

Technological Characteristics

Metallic bone fixation system consisting of anterior and lateral plates and locking/non-locking screws. Features include a central hole for axial compression screws and an anterior window for bone grafting and fluoroscopic visualization. Mechanical properties are equivalent to predicate devices.

Indications for Use

Indicated for patients requiring arthrodesis of the ankle, specifically tibiotalocalcaneal and tibiotalar joints.

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.

• Arthrex Ankle Fusion Plating System (K141735)

Dear Brian Smekal:

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. 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);

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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

| Device<br>Description | The AlignX Ankle Fusion System is a bone fixation device consisting of an anatomical,<br>anterior and lateral tibia plates and various locking and non-locking screws and a set of<br>instruments used for implant site preparation and delivery. The plates are available in<br>various geometries. The anterior plate is available three configurations, a slim plate and a 2-<br>tab plate (available in two widths). A central hole in the plate allows for angled placement of<br>a "home run" screw to obtain axial compression across the tibiotalar (TT) or<br>(tibiotalarcalcaneal) (TTC) joints. The 2-tab plate is designed with an anterior "window" to<br>allow autologous grafting of the TT and visualization of fusion under fluoroscopy. The<br>lateral plate is available in two geometries, one for tibiotalar (TT) joint fusion and one for<br>tibiotalarcalcaneal (TTC) fusions. |
| Indications for<br>use | The AlignX Ankle Fusion System is intended to facilitate arthrodesis of the ankle including<br>tibiotalocalcaneal and tibiotalar joints. |
| Statement of<br>Technological<br>Comparison | The AlignX Ankle Fusion System and predicate devices are equivalent in terms of<br>indications for use, design, and material mechanical properties. |
| Non-clinical<br>Testing | An engineering analysis demonstrated that the new plates and screw sizes do not introduce a<br>new worse case in terms of strength. |
| Clinical Testing | No clinical testing was performed. |
| Conclusion | The AlignX Ankle Fusion System is substantially equivalent to its predicate device. This<br>conclusion is based upon indications for use, principles of operation, design, and mechanical<br>test data. |
