Device Description

Tornier HRS (formerly branded Aequalis Flex Revive Shoulder System) is a fully convertible anatomic and reversed shoulder arthroplasty system that is designed to be used with existing Tornier implant systems. It is a non-constrained system intended for total or partial replacement of the glenohumeral articulation.

The Tornier Humeral Reconstruction System (Tornier HRS) is a line existing Aequalis™ Flex Revive™ Shoulder System (AFR) (K191318, cleared June 14, 2019) that builds upon the AFR system with additional sized distal stems, proximal bodies, and reversed insert trays, new monoblock stems, humeral head couplers and MR Conditional labeling for Tornier HRS line extension components.

The Tornier Perform Humeral System (Tornier PHS-Stem) (K2013 15) is also being expanded to include additional sized Vitamin E UHMWPE reversed inserts and a renaming of these inserts for clarity.

AI/ML Overview

This is a 510(k) Premarket Notification from the FDA for a medical device called the Tornier Humeral Reconstruction System (Tornier HRS) and the Tornier Perform Humeral System - Stem (Tornier PHS-Stem). This document focuses on demonstrating substantial equivalence to previously cleared predicate devices, rather than establishing new acceptance criteria and proving performance against them through a clinical study.

Therefore, the sections of your request regarding acceptance criteria, study details, expert consensus, and effects size are not applicable (N/A) in this context. The primary evidence presented here is non-clinical testing to show that the modified device and its extensions are as safe and effective as the predicate devices.

Here's a breakdown based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (N/A - Not a de novo device, relies on substantial equivalence)Reported Device Performance (Non-Clinical Testing)
N/ADemonstrated substantial equivalence to predicate devices.
N/APassed Fatigue testing with corrosion evaluation.
N/APassed Locking mechanism fatigue testing.
N/APassed Pull-out and torque-out testing.
N/APassed Wear and range of motion testing.
N/APassed Material characterization testing.
N/APassed Biocompatibility evaluation.
N/APassed Packaging and shelf-life evaluations.
N/APassed Distribution testing.
N/APassed Sterilization evaluation.
N/APassed Endotoxin testing.
N/APassed MRI compatibility evaluation.
N/APassed System Compatibility Testing.

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

  • Test Set Sample Size: Not applicable. The document refers to "non-clinical testing," which typically involves bench testing of components and assemblies, not human subjects.
  • Data Provenance: Not applicable. The testing is described as non-clinical performance testing, likely conducted in a laboratory setting by the manufacturer.

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

  • Number of Experts: Not applicable. This type of non-clinical testing does not involve establishing ground truth from expert consensus in the way a diagnostic AI would. The "ground truth" is determined by established engineering and material science standards and test methods.
  • Qualifications of Experts: N/A.

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

  • Adjudication Method: Not applicable. Adjudication methods like 2+1 or 3+1 are used for human expert review in clinical studies or for establishing ground truth in diagnostic performance evaluations, which is not what occurred here.

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:

  • MRMC Study: No. The document explicitly states: "No clinical studies were performed."
  • Effect Size: Not applicable.

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

  • Standalone Performance: Not applicable. This is a physical orthopedic implant system, not a software algorithm or AI device.

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

  • Type of Ground Truth: Not applicable. For non-clinical performance testing of medical devices, "ground truth" in the diagnostic sense is not typically generated. Instead, performance is measured against established engineering specifications, material properties, and mechanical limits as defined by relevant standards (e.g., ISO, ASTM).

8. The sample size for the training set:

  • Training Set Sample Size: Not applicable. This is not a machine learning or AI device that requires a training set.

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

  • Ground Truth for Training Set: Not applicable. This is not a machine learning or AI device.
