The SMR Shoulder System is intended for partial or total, primary or revision shoulder joint replacement.

The SMR Anatomic Shoulder System is indicated for partial or total, primary or revision shoulder joint replacement in patients suffering from disability due to:

• non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis;
• . inflammatory degenerative joint disease such as rheumatoid arthritis;
• treatment of acute fractures of the humeral head that cannot be treated with other fracture fixation methods;
• revision of a failed primary implant; in case of SMR Short Stems only if sufficient bone stock remains); .
• cuff tear arthropathy (CTA Heads only); .
• glenoid arthrosis without excessive glenoid bone loss: A1, A2 and B1 according to Walch classification (SMR TT Hybrid Glenoid only). .

The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator coff deficient joint with severe arthropathy (disabled shoulder). The patients joint must be anatomically suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

The SMR TT Hybrid Glenoid Reverse Baseplate must not be used in cases of excessive glenoid bone loss and/or when bone graft is needed.

The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs are intended for cemented and uncemented use as specified in the following table.

In the Anatomic shoulder the humeral consists of the humeral stem, the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented.

The Anatomic glenoid construct consists of an all polyethylene glenoid with metal peg or a metal back assembled with a liner; the Reverse glenoid consists of a metal back/connector/glenosphere construct or of a peg/baseplate/glenosphere construct. On the glenoid side, the fixation of the all polyethylene glenoid with metal peg or the metal back determines if the construct is cemented or uncemented.

The SMR 140° Reverse Humeral Bodies (SMR 140° Reverse Humeral Body, SMR 140° Short Reverse Humeral Body, SMR 140° Finned Reverse Humeral Body) are manufactured from Ti6Al4V alloy (ASTM F1472 - ISO 5832-3); they are for tapercoupling with previously cleared Humeral extension (K113523), SMR CTA Head Adaptor for Reverse Humeral Body (K131112), Reverse Liners (K110598, K142139) and Humeral stems (K100858, K101263, K111212, K191963).

This document is a 510(k) premarket notification for the SMR 140° Reverse Humeral Body, a component of a shoulder replacement system. As such, it does not contain information about acceptance criteria or a study proving that an AI device meets acceptance criteria.

The document describes a medical device (SMR 140° Reverse Humeral Body for shoulder replacement) and its substantial equivalence to predicate devices, supported by non-clinical mechanical testing. It explicitly states that clinical testing was not necessary to demonstrate substantial equivalence.

Therefore, the requested information points regarding AI acceptance criteria and studies (sample size, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance, ground truth type for training/test sets, and training sample size) are not applicable to this document.

Ask a specific question about this device

The Titan™ Reverse Shoulder System is indicated for use in a grossly deficient rotator cuff joint with severe arthropathy or a previous failed joint replacement with a grossly deficient rotator cuff joint. The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.
The glenoid base plate is intended for cementless application with the addition of screws for fixation.
The humeral stem is indicated for cemented or uncemented use and the humeral body component is intended for cementless use.

The Integra TITAN Reverse Shoulder System is a modular shoulder prosthesis system. The humeral components consist of humeral stems, varying heights of reverse bodies, and humeral poly liners. The poly liners are available in varying thicknesses and constraints to achieve stability and offset of the glenohumeral joint. The variable length reverse bodies and proximally-filling shape are designed to accommodate the natural humeral geometry, providing stable fixation as well as proximal bone loading. The glenoid components are composed of a baseplate secured by a central compression screw and 4 peripheral screws, two of which can be locked. A glenosphere is attached to the baseplate via taper lock. Glenospheres are available in varying offsets and lateralizations.

The provided document describes the Integra TITAN Reverse Shoulder System, a medical device. The information details nonclinical testing performed to establish substantial equivalence to predicate devices, rather than a study proving the device meets specific acceptance criteria in a clinical or AI-assisted diagnostic context.

Therefore, the following information, as requested in the prompt, is not available in the provided text:

• A table of acceptance criteria and reported device performance (in a diagnostic context)
• Sample size used for the test set and data provenance (for diagnostic performance)
• Number of experts used to establish ground truth for the test set
• Qualifications of those experts
• Adjudication method
• If a multi reader multi case (MRMC) comparative effectiveness study was done
• Effect size of human readers improving with AI vs without AI assistance
• If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
• The type of ground truth used (expert consensus, pathology, outcomes data, etc.) for a diagnostic algorithm
• The sample size for the training set (for a diagnostic algorithm)
• How the ground truth for the training set was established (for a diagnostic algorithm)

However, I can extract information regarding the nonclinical performance testing that was conducted for the device. The document explicitly states: "Clinical performance data were not necessary to support substantial equivalence." This means no human clinical trials (as one might expect a diagnostic AI to undergo) were presented for this 510(k) submission.

Here's what can be extracted about the device's nonclinical performance:

Nonclinical Testing and Acceptance Criteria:

The Integra TITAN Reverse Shoulder System underwent several nonclinical performance tests to confirm its ability to perform under expected clinical conditions. The acceptance criteria for each test are implicitly met as the summary states the "System met all acceptance criteria" or "is acceptable" for each respective test.

Additional Notes:

• Sample Size (for nonclinical tests): The document does not specify the exact sample sizes (number of units tested) for each nonclinical test, but refers to "worst-case components or constructs" being tested.
• Data Provenance (for nonclinical tests): These are laboratory-based engineering tests, not clinical data from patients or a specific country.
• Ground Truth (for nonclinical tests): The ground truth for these tests is based on established engineering principles, biomechanical justification, industry standards (e.g., ASTM F2009-00(2011)), and FDA guidance documents.
• Training Set (for nonclinical tests): This concept does not apply to the nonclinical testing described. These are physical performance assessments against predefined engineering parameters.
