Tornier Humeral Reconstruction System (Tornier HRS)

IN ANATOMIC:
The Tornier HRS is to be used only in patients with an intact or reconstructable rotator cuff, where it is intended to provide increased mobility and stability and to relieve pain. The Tomier HRS is indicated for use as a replacement of shoulder joints disabled by:

• · Rheumatoid arthritis with pain
• · Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis)
• · Correction of functional deformity
• · Fractures of the humeral head
• · Traumatic arthritis
• · Revision of other devices if sufficient bone stock remains

IN REVERSE:
The Tornier HRS is indicated for use as a replacement of shoulder joints for patients with a functional deltoid muscle with pain disabled by:

• · Rheumatoid arthritis
• · Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis)
• · Correction of functional deformity
• · Fractures of the humeral head
• · Traumatic arthritis
• · Massive and non-repairable rotator cuff tear
• · Revision of other devices if sufficient bone stock remains

The reversed tray and polyethyiene inset are in the conversion from an anatomic to reversed shoulder arthroplasty without the removal of the humeral assembly during revision surgery for patients with a functional deltoid muscle.

Notes:

• · All components are single use.
• · The coated humeral stem is intended for cemented or cementless use.
• · The all-poly glenoid components are intended for cemented use only
• · The glenoid sphere implant is anchored to the bone with screws and is for non-cemented fixation.
• · Titanium humeral heads are intended for patients with suspected cobalt alloy material sensitivity.
• The wear properties of Titanium and Titanium alloys are inferior to that of cobalt alloy. A Titanium humeral head is not recommended for patients who lack a suspected material sensitivity to cobalt alloy.

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:

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.
