Cemented Acqualis Reversed prosthesis:

It is indicated for patients with a functional deltoid muscle as a total shoulder replacement for the relief of pain and significant disability following arthropathy associated with the massive and non repairable rotator cuff-tear. This device is also indicated for the prosthetic revisions with massive and non repairable rotator cuff-tear. Only the humeral components are for cemented use. The glenoid implant is anchored to the bone with 4 screws and is for non-cemented fixation.

When during the primary surgery the glenoid bone stock appears to be insufficient to bear the reversed glenoid components or when glenoid bone fracture occurs during the surgical procedures, the hemi-prosthesis adaptor and the union screw can be adapted to the humeral components in order to transform the Aequalis Reversed prosthesis into a non reversed hemi-prosthesis.

When, in case of revision of a Aequalis Reversed prosthesis, the glenoid bone stock appears to be insufficient to again implant a base plate and a sphere of Aequalis Reversed range, the use of the hemi-prosthesis adaptor and the union screw allows for the transformation of the Aequalis Reversed prosthesis in to a non reversed hemi-prosthesis in order to avoid the revision of the humeral components.

Uncemented Acqualis Reversed prosthesis:

The Aequalis Reversed Shoulder Prosthesis is intended to relieve pain and significant disability . following massive and non repairable cuff-tear associated to arthropathy and following massive cuff-tear arthropathy. In this case, the rotator muscles of the shoulder (supraspinatus, teres minor and long head of the biceps) are no more useful for mobility, and only the deltoid (for abduction and external rotation) and the subscapularis (for internal rotation) are functional.

Therefore, the usual goal of such surgery is to restore the shoulder joint to facilitate its working condition and to reduce or eliminate pain. The Aequalis Reversed Shoulder Prosthesis is intended to accomplish these goals. Its reversed design allows to medialize the center of rotation of the shoulder, lengthening the deltoid muscle lever arm.

The Aequalis Reversed Shoulder Prosthesis is a semi-constrained system composed of a humeral and a glenoid parts.

The present device modification submission consists of:

• the addition of humeral stems with hydroxylapatite coating,
• the addition of 2 sizes of metaphyses with hydroxylapatite coating, •
• the update of the Aequalis Reversed Shoulder Prosthesis indications for use. .

I am sorry, but the provided text does not contain information about acceptance criteria or a study proving device performance in the context of an AI/ML medical device.

The document is a 510(k) premarket notification for the "Aequalis Reversed Shoulder Prosthesis," a traditional medical device (implantable shoulder prosthesis). It focuses on demonstrating substantial equivalence to predicate devices, not on evaluating the performance of an AI/ML algorithm.

Therefore, I cannot provide the requested information, which includes:

1. Acceptance criteria table
2. Sample size and data provenance for test sets
3. Number and qualifications of experts for ground truth
4. Adjudication method
5. MRMC comparative effectiveness study results
6. Standalone algorithm performance
7. Type of ground truth used
8. Sample size for training set
9. Ground truth establishment for training set
