Device Description

The DePuy Global™ Crosslink Glenoids are offered in an anchor peg and a fin design. The Crosslink Glenoid anchor peg design consists of sizes: 40mm, 48mm, 48mm, 52mm, 56mm and 56mmXL. The Crosslink Glenoid in the fin design consists of seven sizes: 40mmXS, 40mm, 44mm, 52mm, 52mm, 56mm and 56mmXL. Both the anchor peg and fin designs have a lateral surface that is concave and designed to articulate with the DePuy Global™ line humeral heads indicated for ase in total shoulder arthroplasty. The fixation surface has a central fin or peripheral pegs and is intended to be attached to the glenoid fossa of the scapula with bone cement.

AI/ML Overview

The provided text is a 510(k) premarket notification for a medical device, the DePuy Global™ Shoulder Crosslink Glenoid. This type of document is for demonstrating substantial equivalence to a predicate device, not for proving a device meets acceptance criteria through a study with the detailed structure you've requested.

Therefore, many of the specific details you've asked for, such as acceptance criteria in the context of a performance study, sample sizes for test and training sets, expert qualifications, and adjudication methods for AI performance, are not applicable and not present in this document.

This submission focuses on justifying that the new device (Crosslink Glenoid) is substantially equivalent to existing, legally marketed devices, primarily by demonstrating similar design and intended use, and emphasizing a material difference (highly cross-linked polyethylene) with an additional claim of reduced wear based on shoulder simulator wear studies.

Here's an attempt to answer your questions based only on the provided text, while highlighting what information is missing:

Acceptance Criteria and Study to Prove Device Meets Them

1. Table of acceptance criteria and the reported device performance:

Acceptance Criteria (Inferred from Substantial Equivalence Basis)	Reported Device Performance (Summary from Section {1})
Design: Same as predicate Glenoid components (K981497, K914000)	Has the same design as predicate Glenoid components.
Intended Use: Same as predicate Glenoid components	Has the same intended use as predicate Glenoid components.
Indications: Same as predicate Glenoid components	Has the same indications as predicate Glenoid components.
Material: Same as predicate Tibial Inserts (K040166)	Made from the same cross-linked polyethylene as predicate Tibial Inserts.
Wear Reduction: Expected to show reduced wear compared to Enduron polyethylene.	Shown to have a reduction in wear compared to currently available Enduron polyethylene, based on shoulder simulator wear studies.

Note: The acceptance criteria here are inferred from the basis of substantial equivalence. They are not explicit, quantitative performance targets as might be found in a clinical trial or a performance study designed to demonstrate specific metrics (e.g., accuracy, sensitivity, specificity for an AI device). The primary acceptance criterion here is "substantial equivalence" to the predicate devices, with an added claim for improved wear.

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

Sample Size for Test Set: Not applicable. The "study" mentioned is "shoulder simulator wear studies," which refers to in-vitro mechanical testing, not a human-data-based test set in the context of AI. The number of components tested in these simulator studies is not specified.
Data Provenance: Not applicable for human data. The "study" is a laboratory-based, in-vitro shoulder simulator wear study.

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

Not applicable. This device is a physical implant, not an diagnostic algorithm requiring expert "ground truth" labels.

4. Adjudication method for the test set:

Not applicable. This device is a physical implant.

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 device.

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

Not applicable. This is not an AI device.

7. The type of ground truth used:

The "ground truth" for the wear reduction claim is based on physical measurements of wear from in-vitro shoulder simulator studies.

8. The sample size for the training set:

Not applicable. There is no "training set" in the context of an AI device for this product.

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

Not applicable. There is no "training set" in the context of an AI device for this product.

BASIS OF SUBSTANTIAL EQUIVALENCE:

The DePuy Global™ Crosslink Glenoids have the same design, intended use and indications as the Glenoid components cleared in K981497 and K914000 as part of DePuy's Global Shoulder System. The difference between the Crosslink Glenoids proposed in this submission and the Glenoids in the Global Shoulder System is the type of polyethylene used to manufacture the components. The Crosslink Glenoids are made from highly cross-linked polyethylene, which has been to shown to have a reduction in wear compared to currently available Enduron polyethylene. The Crosslink Glenoids are made from the same cross-linked polyethylene as that cleared in the DePuy Sigma XI.K. Tibial Inserts, listed in K040166. Due to the similarities noted DePuy believes the Crosslink Glenoids to be substantially equivalent in design to the Glenoids of DePuv Global Shoulder System and in material to the DePuy Sigma XLK Tibial Inserts, with the additional claim of reduced wear, based on results of shoulder simulator wear studies of these devices.

Dear Ms. Heck:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
