AI/ML Overview

The provided text does not contain detailed acceptance criteria for a medical device or a comprehensive study demonstrating that the device meets these criteria. The document is primarily a 510(k) premarket notification for shoulder prosthetic systems (ASHCOM™ Shoulder System, Anatomical Shoulder™ System, Anatomical Shoulder™ Combined System), aiming to establish substantial equivalence to previously cleared predicate devices.

Instead, the document focuses on:

  • Indications for Use: What conditions the devices are intended to treat.
  • Device Description: The components and general design of the prosthetic systems.
  • Comparison to Predicate Device: How the new devices are similar to existing, legally marketed devices.
  • Performance Data (Nonclinical): A list of non-clinical tests performed to support safety and effectiveness, particularly for the ASHCOM Shoulder System and the MRI compatibility of the Anatomical Shoulder systems.

Here's an analysis based on the information provided, highlighting what's present and what's explicitly absent:


1. Table of Acceptance Criteria and Reported Device Performance

The document does not provide a formal table of acceptance criteria with specific quantitative targets and corresponding device performance data to demonstrate compliance.

Instead, it lists the types of non-clinical tests performed to show safety and equivalence:

Test TypeReported Purpose/Outcome
Finite Element Stress analysisPerformed under worst-case conditions; aimed to demonstrate safety and effectiveness, and substantial equivalence.
Cyclic fatigue testingPerformed under worst-case conditions; aimed to demonstrate safety and effectiveness, and substantial equivalence.
Accelerated Corrosion Fatigue TestingPerformed; aimed to demonstrate safety and effectiveness, and substantial equivalence.
Static taper connection testing per ASTM F2009Performed; aimed to demonstrate safety and effectiveness, and substantial equivalence.
MRI compatibility evaluationEvaluated per "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment" Guidance (August 2014) to support "MR Conditional" labeling for the Anatomical Shoulder and Anatomical Shoulder Combined Systems.

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

For the non-clinical tests listed, the document does not specify sample sizes (e.g., number of prostheses tested) or data provenance (e.g., country of origin, retrospective/prospective). These details would typically be found within the full test reports, which are not included in this summary.

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

This section is not applicable as the document describes non-clinical performance testing of physical devices (implants), not a study involving evaluation by medical experts to establish ground truth for a diagnostic or AI-driven system.

4. Adjudication method for the test set

This section is not applicable for the same reasons as point 3.

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

This section is not applicable. The device is an orthopedic implant, not an AI-assisted diagnostic or imaging device. Therefore, no MRMC study involving human readers and AI assistance was conducted or mentioned.

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

This section is not applicable. The device is an orthopedic implant and does not involve an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For the non-clinical performance tests, "ground truth" would not be established by expert consensus, pathology, or outcomes data in the traditional sense. Instead, the "ground truth" or reference state is defined by engineering specifications, material properties, and regulatory standards (e.g., ASTM F2009 for taper connection testing). The tests aim to demonstrate that the physical properties and performance of the device meet these predefined engineering and safety criteria.

8. The sample size for the training set

This section is not applicable. The device is an orthopedic implant, and there is no mention of an algorithm or AI model that would require a training set.

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

This section is not applicable for the same reasons as point 8.


Summary of what the document does indicate regarding device performance and acceptance:

The submission relies on non-clinical performance testing and analysis to demonstrate the safety and effectiveness of the ASHCOM Shoulder System and the existing Anatomical Shoulder systems (for MRI compatibility labeling) and establish their substantial equivalence to predicate devices. The listed tests (FEA, cyclic fatigue, corrosion fatigue, static taper connection) are standard for orthopedic implants to assess mechanical integrity, durability, and material performance. For MRI compatibility, the evaluation followed FDA guidance, suggesting a series of tests to confirm the "MR Conditional" status.

The statement "Results of non-clinical performance testing and analyses demonstrate that the ASHCOM Shoulder System is safe and effective and substantially equivalent to the predicate devices" serves as the overall conclusion regarding acceptance based on the conducted studies, without detailing the specific quantitative acceptance criteria or results in this summary. The FDA's clearance (K170711) indicates that they found the provided non-clinical data sufficient to establish substantial equivalence.
