Here's an analysis of the provided text regarding the acceptance criteria and supporting study for the NEO™ Anterior Cervical Plate:

This document is a 510(k) Summary of Safety and Effectiveness for a medical device called the NEO™ Anterior Cervical Plate. In the context of 510(k) submissions, the “acceptance criteria” and "study that proves the device meets the acceptance criteria" are generally framed in terms of demonstrating substantial equivalence to a predicate device, rather than detailed performance metrics against specific, quantitative acceptance criteria common in software or diagnostic device evaluations.

Here's a breakdown based on the information provided:

1. Table of Acceptance Criteria and Reported Device Performance

Note: For a 510(k) submission of this type of orthopedic implant, "acceptance criteria" are generally demonstrated through equivalence to a predicate device in terms of safety and effectiveness, which is supported by material testing and biomechanical testing aligning with recognized standards. Specific quantitative performance targets are less frequently disclosed in the summary documents, especially for devices establishing substantial equivalence to prior-generation predicate devices.

Study Information:

2. Sample Size Used for the Test Set and Data Provenance

• The document mentions "Biomechanical testing in accordance with ASTM F1717." ASTM F1717 is a standard for "Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model." This standard typically outlines how tests should be performed and what parameters to measure (e.g., stiffness, displacement, fatigue life), but it does not specify a "sample size" in the clinical sense (e.g., number of patients).
• For biomechanical testing, the "sample size" would refer to the number of test specimens (e.g., number of device constructs tested). This specific number is not provided in the document.
• The data provenance is laboratory testing, not human or patient data. Therefore, the concepts of "country of origin of the data" and "retrospective or prospective" do not apply.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

• This question is not applicable to this type of device and study. The "ground truth" for biomechanical testing is typically established by the adherence to and results of a recognized international standard (ASTM F1717) and engineering principles, not through expert consensus on clinical cases. The "experts" would be the engineers and technicians conducting the tests and interpreting the results against the standard and predicate device data.

4. Adjudication Method for the Test Set

• Not applicable. Adjudication methods (like 2+1, 3+1) are used for clinical studies involving human readers or evaluators, not for direct biomechanical engineering tests.

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

• No. This is a hardware orthopedic implant (anterior cervical plate). An MRMC study is relevant for diagnostic devices, particularly AI-powered ones. There is no AI component mentioned or implied.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

• No. This is a hardware orthopedic implant. This question pertains to AI/software.

7. The Type of Ground Truth Used

• The "ground truth" for demonstrating substantial equivalence for this device is based on engineering standards and direct physical measurements derived from biomechanical testing, compared to the known performance of a predicate device. It is not based on expert consensus, pathology, or outcomes data in the clinical sense.

8. The Sample Size for the Training Set

• Not applicable. There is no "training set" as this is not an AI/machine learning device.

9. How the Ground Truth for the Training Set Was Established

• Not applicable. There is no "training set."

In summary:

The provided document describes a 510(k) submission for a physical medical implant. The primary "study" mentioned is biomechanical testing in accordance with ASTM F1717. This testing serves to demonstrate that the device performs mechanically in a manner substantially equivalent to its predicate device(s), thereby establishing its safety and effectiveness for its intended use and material composition. The questions regarding AI, expert consensus, clinical sample sizes, and adjudication methods are not relevant to this type of regulatory submission or device.

Here's an analysis of the provided text regarding the Life Spine, LLC NEOTM Cervical Plating System, focusing on acceptance criteria and study details.

Important Note: The provided document is a 510(k) Summary, which typically focuses on demonstrating substantial equivalence to a predicate device rather than presenting a formal clinical study with strict acceptance criteria for a novel device. Therefore, the information requested in your prompt regarding acceptance criteria, sample sizes, ground truth establishment, expert qualifications, and MRMC studies is not explicitly detailed in this type of document. The study described is mechanical testing, not a clinical study.

Acceptance Criteria and Device Performance (Based on provided text)

The document primarily discusses mechanical testing to demonstrate substantial equivalence, not clinical performance metrics or specific acceptance criteria for diagnostic accuracy (which would be relevant for devices that process medical images or data).

Study Details (Based on provided text):

Since this is a 510(k) summary for a spinal implant, the "study" referred to is mechanical bench testing, not a clinical trial evaluating human performance or AI accuracy. Therefore, many of your requested fields are not applicable or cannot be extracted from this document.

Summary of Device and Approval:

The Life Spine, LLC NEOTM Anterior Cervical Plate System is a medical device for temporary stabilization of the anterior spine from C2 to T1 during cervical spinal fusions. It is indicated for various conditions including degenerative disc disease, trauma, and tumors. The device consists of titanium alloy plates, screws, and locking tabs.

The 510(k) submission (K040844) demonstrated substantial equivalence to two predicate devices: Interpore Cross International Anterior Cervical Plate System (K002592) and Howmedica Osteonics Corporation Reflex Anterior Cervical Plate System (K031702). The primary evidence for this equivalence was mechanical testing (static and fatigue strength) which showed comparable properties to the predicate devices. The FDA reviewed the submission and determined that the device was substantially equivalent, allowing it to be marketed.
