The Reverse Shoulder Prosthesis Monoblock is indicated for patients with a functional deltoid muscle with a grossly deficient rotator cuff shoulder joint with severe arthropathy or a previously failed joint replacement with a grossly deficient rotator cuff shoulder joint:
- . In cases of fracture of glenohumeral joint from trauma or pathologic conditions of the shoulder, including humeral head fracture or displaced 3-or 4-part fractures of proximal humerus.
- In cases of bone defect in proximal humerus. .
The patient's joint must be anatomically and structurally suited to receive the selected implant(s).
The glenoid baseplate is intended for cementless application with the addition of screws for fixation. The humeral stem is intended for cemented use only.
The Reverse Shoulder Prosthesis (RSP) is indicated for salvage procedures for irreparable rotator cuff. failed hemi or total shoulder arthroplasty with irreparable rotator cuff, and for fracture in which the tuberosity and rotator cuff are irreparable. The RSP is designed so that the "ball" of the articulation fits into the glenoid baseplate, and the "cup" of the articulation fits into a metal cup attached to the humeral stem. The components included in this system are a glenoid head, a humeral socket, a humeral stem, a glenoid baseplate, and baseplate screws.
The Monoblock design consists of:
- . a non-modular stem designed by joining the humeral socket with the humeral stem (sizes 6, 7, 8, 10 and 12);
- . humeral inserts in size 44 semi-constrained UHMWPe and +4 offset inserts in sizes 32, 36, 40 and 44 (standard and semi-constrained UHMWPe). Currently cleared sizes of inserts (32, 36, 40, and 44 in standard poly and size 32, 36, and 40 semi-constrained UHMWPe) are also compatible with the monoblock design.
- . glenoid components will be the same as currently cleared under K 100741, K092873, K051075, and K041066
Here's an analysis of the provided text regarding the Reverse® Shoulder Prosthesis Monoblock, focusing on the requested acceptance criteria and study information:
Based on the provided text, the device is a medical implant (shoulder prosthesis), and the information is from an FDA 510(k) clearance document. For this type of device, "acceptance criteria" and "device performance" are typically related to mechanical and material properties, biocompatibility, and functional integrity under simulated physiological conditions. The document does NOT describe the acceptance criteria or reported device performance for a software-based AI/ML device. The questions about AI-specific criteria (sample size, experts, adjudication, MRMC, standalone performance, training data) are not applicable to this medical device submission.
Here's a breakdown of what is available in the document related to testing, rephrased to fit the structure of your request where possible, and indicating where information is not provided:
1. Table of Acceptance Criteria and Reported Device Performance
As this is a mechanical medical implant and not a software AI/ML device, the table below reflects the type of information that would be relevant for such a device. The provided text does not include specific numerical acceptance criteria or detailed reported performance values for the device's mechanical properties, as these studies were already completed for previous versions.
| Acceptance Criteria Category (Hypothetical for Mechanical Device) | Reported Device Performance (Summary from Document) |
|---|---|
| Mechanical Strength/Fatigue Life | "additional testing was not necessary to support equivalence" (referring to prior non-clinical testing) |
| Material Biocompatibility | Implied as part of "prior non-clinical testing" for previously cleared components. |
| Wear Resistance / Articulation Properties | Implied as part of "prior non-clinical testing" for previously cleared components. |
| Fit and Function with existing components | "Currently cleared sizes of inserts... are also compatible with the monoblock design." |
2. Sample size used for the test set and the data provenance
- Sample Size: Not explicitly stated for specific mechanical tests in this document. The document refers to "prior non-clinical testing" performed for previously cleared components (K100741, K092873, K051075, and K041066). The current submission states no additional testing was necessary.
- Data Provenance: Not applicable in the context of clinical data for AI/ML. For mechanical testing, this typically refers to the lab where the tests were conducted, which is not detailed here.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- This question is not applicable as the submission is for a mechanical medical device, not an AI/ML diagnostic or predictive tool that requires expert-established ground truth from data.
4. Adjudication method for the test set
- This question is not applicable as the submission is for a mechanical medical device, not an AI/ML diagnostic or predictive tool that requires adjudication of expert opinions.
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 question is not applicable as the submission is for a mechanical medical device, not an AI/ML diagnostic or predictive tool. The document explicitly states "Clinical Testing: None provided."
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- This question is not applicable as the submission is for a mechanical medical device, not an AI/ML algorithm.
7. The type of ground truth used
- This question is not applicable in the context of AI/ML ground truth from expert consensus, pathology, or outcomes data. For a mechanical device, "ground truth" would be the known mechanical properties of materials, validated engineering models, and the performance of predicate devices against established standards during non-clinical testing.
8. The sample size for the training set
- This question is not applicable as the submission is for a mechanical medical device, not an AI/ML algorithm.
9. How the ground truth for the training set was established
- This question is not applicable as the submission is for a mechanical medical device, not an AI/ML algorithm. The "ground truth" for mechanical testing is established through standardized engineering test methods and material science principles.
Summary of Device-Specific Information from the Text:
The document concerns the "Reverse® Shoulder Prosthesis Monoblock," an update to an existing shoulder implant. The submission is for a 510(k) clearance, indicating it is a "substantially equivalent" device to a predicate (K082120 - Tornier Aequalis@-Reversed Fracture prosthesis).
The key takeaway regarding testing is:
- Non-Clinical Testing: "After completing review of prior non-clinical testing conducted for this system and submitted under K100741, K092873, K051075, and K041066, it was concluded that additional testing was not necessary to support equivalence." This means the current device leverages prior testing data for its components or overall system design, implying that component-level mechanical, material, and biocompatibility requirements were met previously and are assumed to hold for the new configuration due to design similarities to the predicate and previously cleared components.
- Clinical Testing: "None provided." This is common for 510(k) submissions, especially for modifications of existing devices or when non-clinical testing is deemed sufficient to establish substantial equivalence.
