The Univers Revers Modular Glenoid System is indicated for use in a grossly rotator cuff deficient glenohumeral joint with severe arthropathy or a previously failed joint replacement with a gross rotator cuff deficiency. The patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device.
The Univers Revers Modular Glenoid System is indicated for primary, fracture, or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency.
The Univers Revers Modular Glenoid System is porous coated and is intended for cementless use with the addition of screws for fixation.
The proposed devices are augmented modular glenoid baseplates made of titanium with BioSync coating. The proposed devices are half-wedge augmented modular glenoid baseplates available in two sizes (24 and 28). The baseplates are designed to be used cementless with peripheral screws and glenospheres (cleared under K193372 and K173900).
The provided document is a 510(k) summary for a medical device (Univers Revers Modular Glenoid System, Half Augment Baseplate). It focuses on demonstrating substantial equivalence to a predicate device through material, design, and performance testing, rather than presenting clinical study results for diagnostic accuracy or efficacy with human participants. Therefore, many of the requested criteria (like sample size for test/training sets, expert qualifications, adjudication methods, MRMC studies, effect sizes, and specific ground truth types like pathology or outcomes data) are not applicable or cannot be extracted from this type of regulatory submission.
However, I can extract the acceptance criteria related to mechanical performance and the study that was performed to demonstrate that the device met these criteria.
Acceptance Criteria and Study for Univers Revers Modular Glenoid System, Half Augment Baseplate
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criterion | Reported Device Performance | Study Performed |
|---|---|---|
| Mechanical Stability (specifically Rocking Horse Testing) | Achieved standard requirements. | Mechanical testing per ASTM F2028. |
| MRI Safety | Met requirements of FDA guidance and ASTM F2182. | MRI testing per FDA guidance and ASTM F2182. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a "test set" in the context of human participant data, as this is a non-clinical submission for a Class II medical device. The studies mentioned are primarily benchtop or in-vitro tests:
- Mechanical Testing (ASTM F2028): The sample size for this testing is not explicitly mentioned but would typically involve multiple units of the device to ensure statistical robustness. The provenance is from laboratory testing.
- MRI Testing (FDA guidance and ASTM F2182): The sample size for this testing is not explicitly mentioned but involves the device itself. The provenance is from laboratory testing.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Not applicable. The studies performed are mechanical and MRI safety tests, not studies requiring expert clinical interpretation for ground truth establishment.
4. Adjudication Method for the Test Set
Not applicable. This is not a study requiring adjudication of clinical findings.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. An MRMC comparative effectiveness study was not done. This device is a shoulder prosthesis and the submission focuses on its physical and material properties, not diagnostic performance or human-AI interaction.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
Not applicable. This device is a physical medical implant, not an algorithm or AI-based software.
7. Type of Ground Truth Used
The "ground truth" for the performance studies is based on established engineering standards and regulatory guidelines:
- Mechanical Performance: The "ground truth" is defined by the requirements of ASTM F2028, a recognized standard for testing glenoid component stability.
- MRI Safety: The "ground truth" is defined by FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" and ASTM F2182, a standard for measuring RF-induced heating in MRI.
8. Sample Size for the Training Set
Not applicable. There is no training set in the context of this device and the presented performance data. This is not a machine learning or AI-based device.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set.

Dear Ivette Galmez:
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
