## Intended Use

The Cadence Total Ankle System is designed to treat ankle arthritis through replacement of the ankle joint with a prosthesis, thereby reducing pain, restoring alignment, and allowing for movement at the replaced joint. The Cadence Total Ankle System is indicated for use to treat: - Systemic arthritis of the ankle (e.g. rheumatoid arthritis, hemochromatosis) - Primary arthritis (e.g. degenerative disease) - Secondary arthritis (e.g. post-traumatic, avascular necrosis, if minimally 2/3 of the talus is preserved) Cadence Total Ankle System is also indicated for revision surgeries following failed total ankle replacement and non-union/mal-union of ankle arthrodesis. Provided sufficient bone stock is present. Note - In the United States, this device is intended for cemented use only. Note - Outside the United States, this device is intended for cemented or cementless use.

## Device Story

Cadence Total Ankle System is a semi-constrained, cemented ankle prosthesis; replaces ankle joint to reduce pain and restore motion. Components include tibial tray, talar dome, and insert. Insert fixes to tibial tray intra-operatively; acts as bearing surface against talar dome to enable flexion/extension. Used by orthopedic surgeons in clinical/surgical settings. System includes specialized instrumentation for implantation. Modification introduces flat-cut talar dome design option and associated instrumentation. Device provides mechanical joint replacement; benefits include pain relief and restored joint function.

## Clinical Evidence

No clinical data. Substantial equivalence demonstrated via bench testing, including constraint, bone stability, range of motion, fatigue strength, contact area/pressure distribution, and wear analysis.

## Technological Characteristics

Ankle joint metal/polymer semi-constrained cemented prosthesis. Comprised of tibial tray, talar dome, and insert. Available in multiple sizes and configurations. Designed for cemented use in the U.S. (cemented or cementless outside U.S.).

## Regulatory Identification

An ankle joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace an ankle joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces and has no linkage across-the-joint. This generic type of device includes prostheses that have a talar resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a tibial resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Dear Cassidy Lemkau:

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.

| Device<br>Description                | The Cadence Total Ankle System is a prosthesis composed of a tibial tray, a talar<br>dome and an insert. The tibial tray and talar dome are secured to patient anatomy.<br>The insert is rigidly fixed to the tibial tray intra-operatively. The insert acts as a<br>bearing along the talar dome, enabling flexion and extension movement at the<br>replaced joint. Each of the three components is available in a variety of sizes and<br>design configurations intended for both primary and revision surgery<br>applications. The Cadence System also consists of various instrumentation to<br>allow for appropriate implantation of the Cadence Prosthesis.                                                                                                       |
|                                      | The scope of the Cadence System is being extended to include additional options<br>for the talar domes. The new talar dome option features a flat cut design in<br>comparison to the currently commercialized talar dome chamfer cut design. New<br>instrumentation will also be introduced to aid in the implantation of the new flat<br>cut talar dome design.                                                                                                                                                                                                                                                                                                                                                                                                        |
