The Ascension® MOVEMENT™ Great Toe System, Total Arthroplasty is a twopiece implant that is intended to be used as prosthesis for the metatarsophalangeal joint (MTP). The device is intended for cemented use only. Indications for use include:

Painful degenerative metatarso-phalangeal joint change .
Hallux rigidus stage 3 and 4 ◆
Hallux valgus and hallux rigidus .
Hallux limitus with painful arthrofibrosis .
Revisions after moderate proximal phalanx resection .

Device Description

The Ascension® MOVEMENT Great Toe System, Total Arthroplasty device is an anatomically designed, semi-constrained, two-piece device designed for resurfacing of the base of the 1st metatarso-phalangeal (MTP) joint. The device couples with the Ascension metatarsal hemi-arthroplasty device to allow total arthroplasty of the 1st MTP joint. The device is designed for cemented fixation. The device is boxed individually and delivered sterile for single use. The device incorporates four anatomically designed base geometries with appropriately sized stems. The stem is cylindrical with tapered ribs to provide rotational as well as axial stability of the seated implant. System instrumentation is designed to offer precise implant preparation.

AI/ML Overview

The provided text describes the Ascension® MOVEMENT™ Great Toe System, a total arthroplasty device. The submission focuses on establishing substantial equivalence to predicate devices based on testing and geometrical comparison, rather than clinical performance or AI/software system evaluation. Therefore, many of the requested categories are not applicable to this submission.

Here's a breakdown of the requested information based on the provided text:

1. Table of acceptance criteria and the reported device performance

Acceptance Criteria	Reported Device Performance
Interconnection strength testing (axial, shear, bending strength)	Performed to substantiate equivalence. (Specific results not detailed in provided text)
Geometrical comparisons between subject and predicate devices	Completed. (Specific measurements not detailed in provided text)

2. Sample size used for the test set and the data provenance

Not applicable. The submission is for a medical device (great toe implant) and relies on mechanical testing and geometrical comparison, not a test set of data typically used for AI or diagnostic devices.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. Ground truth for a test set is not relevant for this type of device submission.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. Adjudication methods are not relevant for this type of device submission.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is not an AI-assisted diagnostic device.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This is not an algorithm or AI system.

7. The type of ground truth used

Not applicable in the context of clinical "ground truth" as typically defined for diagnostic or AI devices. The "ground truth" for this device's acceptance would be established by validated engineering and biomechanical testing standards for orthopedic implants.

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device.

9. How the ground truth for the training set was established

Not applicable. This is not an AI/machine learning device.

INTENDED USE:

The Ascension® MOVEMENT™ Great Toe System, Total Arthroplasty is a two-piece implant that is intended to be used as prosthesis for the metatarso-phalangeal ioint (MTP). The device is intended for cemented use only. Indications for use include:

. Painful degenerative metatarsophalangeal joint change
. Hallux rigidus stage 3 and 4
. Hallux valqus and hallux rigidus
. Hallux limitus with painful arthrofibrosis
. Revisions after moderate proximal phalanx resection

Substantial equivalence was based upon testing and a geometrical comparison of the subject and predicate devices. Interconnection strength testing, axial, shear and bending strength, was performed to substantiate equivalence. Geometrical comparisons between the subject device, Ascension® MOVEMENT™ Great Toe System and Integra KGTI™ Kinetik Great Toe Implant System (K904724) were completed. The Merete ToeMobile Anatomical Great Toe Resurfacing System (K072251) was used as a template for labeled indications.

There are no significant differences between the Ascension MOVEMENT Great Toe System and other systems currently being marketed which would adversely affect the use of the product. It is substantially equivalent to these other devices in design. function, material and intended use.

Dear Ms. Walton:

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.
