The AOS Anterolateral Proximal Humeral Plate is indicated for fractures, fracture dislocations, osteotomies, and non- unions of the proximal humerus

The AOS Anterolateral Proximal Humeral plates are open reduction internal fixation devices for the temporary fixation of various types of fractures of the humerus and are intended as load sharing devices which may be removed once the fracture has healed. The AOS Anterolateral Proximal Humeral System consists of titanium plates, and proximal and distal locking and non-locking screws. 16 and 18 hole plates are being added to the system. The 16 hole plates are 9.4 inches long. The 18 hole plates are 10.4 inches long.

The provided text describes a medical device, the "AOS Anterolateral Proximal Humeral Plate," which is a metallic bone fixation appliance. The document is a 510(k) premarket notification for modifications being added to the existing system. Crucially, the document explicitly states under the "CLINICAL DATA" section: "There is no clinical data referenced in this special 510(k)."

This means that no clinical study was conducted as part of this specific 510(k) submission to prove the device meets acceptance criteria. The claim of substantial equivalence for the modifications (adding 16 and 18-hole plates) is based on similarities to predicate devices and preclinical testing (though the document states mechanical testing was not necessary due to no anticipated decrease in strength or increase in risk).

Therefore, I cannot provide information on acceptance criteria, device performance, sample sizes, ground truth, expert qualifications, adjudication methods, or MRMC studies for this specific submission because the document explicitly states no clinical data was referenced.

The relevant information is:

• Acceptance Criteria and Reported Device Performance: Not applicable, as no clinical study was referenced for this submission. The submission relies on substantial equivalence to predicate devices and the absence of a need for new mechanical testing for the additions.
• Sample size for test set and data provenance: Not applicable, as no clinical study was referenced.
• Number of experts used to establish ground truth and qualifications: Not applicable.
• Adjudication method for the test set: Not applicable.
• Multi-reader multi-case (MRMC) comparative effectiveness study: No, not applicable.
• Standalone (algorithm only) performance: Not applicable, as this is a physical medical device, not an AI algorithm.
• Type of ground truth used: Not applicable.
• Sample size for the training set: Not applicable, as no clinical study was referenced.
• How the ground truth for the training set was established: Not applicable.

The AOS Anterolateral Proximal Humeral Plate is indicated for fracture dislocations, osteotomies, and nonunions of the proximal humerus.

The AOS Anterolateral Proximal Humeral plates are open reduction internal fixation devices for the temporary fixation of various types of fractures of the humerus and are intended as load sharing devices which may be removed once the fracture has healed. The AOS Anterolateral Proximal Humeral System consists of titanium plates, and proximal and distal locking and non-locking screws.

The provided text describes a 510(k) premarket notification for the "AOS Anterolateral Proximal Humeral Plate." This document is an FDA letter recognizing the device as substantially equivalent to a legally marketed predicate device. As such, it does not contain acceptance criteria or a study proving the device meets those criteria, as these are typically part of a performance study, not a substantial equivalence claim.

Substantial equivalence is established primarily by demonstrating that the new device has the same intended use and the same technological characteristics as the predicate device, or if there are differences, that they do not raise new questions of safety and effectiveness. The document explicitly states: "physical testing was deemed unnecessary, and substantial equivalence was determined in strength and geometry between the proposed plates and predicate plates."

Therefore, based on the provided text, I cannot provide the requested information regarding acceptance criteria and a study proving the device meets them because such a study was not deemed necessary for this 510(k) submission.

Specifically, I cannot extract:

1. A table of acceptance criteria and the reported device performance
2. Sample size used for the test set and the data provenance
3. Number of experts used to establish the ground truth for the test set and their qualifications
4. Adjudication method for the test set
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done
6. If a standalone (algorithm only) performance study was done
7. The type of ground truth used
8. The sample size for the training set
9. How the ground truth for the training set was established

The document focuses on explaining that the new device (AOS Anterolateral Proximal Humeral Plate) is substantially equivalent to a previously cleared predicate device (AOS Proximal Humeral Plate, K080590) because they share the same indications for use, similar geometry and design, fundamental scientific technology, and material.
