    Intended Use

    The Black Diamond™ POCT Spinal System is intended to provide immobilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the cervical spine (Cl to C7) and the upper thoracic spine (TI-T3); traumatic spinal fractures and/or traumatic dislocations: instability or deformity: failed previous fusion (e.g., pseudoarthrosis); tumors involving the cervical/thoracic spine; and degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin, as confirmed by radiographic studies, and degenerative disease with instability. The Black Diamond™ POCT Spinal System is also intended to restore the integrity of the spinal column even in the absences of fusion for a limited time period in patients with advanced stage tumors in whom if e expectancy is of insufficient duration to permit achievement of fusion. To achieve additional levels offixation, the Black Diamond™ POCT Spinal System may be comected to the Osseus Black Diamond™ Pedicle Screw System using transition rods or anatomically-bent rods.

    Device Description

    The Black Diamond™ POCT Spinal System is a posterior cervico-thoracic fixation system intended to provide stabilization to promote fusion of the cervical spine and upper thoracic spine. The Black Diamond™ system contains rods in multiple shapes and sizes, polyaxial screws, set screws, rod connectors and transverse connectors. Connecting components can be locked to the rod in various configurations to accommodate individual patient anatomy.

    AI/ML Overview

    I am sorry, but the provided text does not contain information about the acceptance criteria or a study proving that a device meets such criteria. The document is an FDA 510(k) clearance letter for the "Black Diamond™ POCT Spinal System," which is a posterior cervical screw system.

    It discusses:

    • The FDA's review and determination of substantial equivalence to predicate devices.
    • The device's indications for use.
    • A summary of its technological characteristics.
    • Non-clinical testing performed (mechanical testing per ASTM F1717).

    However, it does not include:

    • A table of acceptance criteria and reported device performance.
    • Details about sample sizes for test sets, data provenance, or ground truth establishment for software/AI performance evaluation.
    • Information on expert panels, adjudication methods, or multi-reader multi-case studies, as these are typically applicable to diagnostic imaging or AI/ML-based medical devices, not to mechanical spinal implants.
    • Information about a standalone (algorithm only) performance study.
    • Ground truth types for software performance.
    • Training set sample sizes or how training set ground truth was established.

    Therefore, I cannot fulfill your request based on the provided input.

    Intended Use

    The Black Diamond Navigation Instruments are intended to be used during the preparation and placement of Black Diamond pedicle screws during spinal surgery to aid the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. The Black Diamond Navigation Instruments are specifically designed for use with the Medtronic Stealth Station System, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as a vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks for the anatomy.

    Device Description

    Black Diamond Navigation Instruments are non-sterile, reusable instruments; including probes, bone taps, and inserters that are operated manually. These instruments are intended to be used within the context and limitations of the indications for use for Osseus Fusion System's FDA-cleared Black Diamond system and the Medtronic Synergy Experience StealthStation System S7 (v2.1.0). Use of these navigation systems provides the surgeon access to real-time, multi-plane 3D images (and 2D images) providing confirmation of hardware placement.

    AI/ML Overview

    The Black Diamond Navigation Instruments are non-sterile, reusable instruments (probes, bone taps, and inserters) intended for use during the preparation and placement of Black Diamond pedicle screws in spinal surgery. The device aims to assist surgeons in precisely locating anatomical structures in open or minimally invasive procedures, specifically designed for use with the Medtronic Stealth Station System.

    Here's an analysis of the provided information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided text does not explicitly state specific quantitative acceptance criteria or detailed reported device performance in a table format. It mentions that "nonclinical testing was performed to show that the subject Black Diamond Navigation Instruments are substantially equivalent to the predicate device" and lists the types of testing: Accuracy testing, Compatibility testing, and Performance testing. It concludes that "The results of these evaluations indicate that the Black Diamond Navigation Instruments are equivalent to predicate devices."

    Without specific numerical thresholds or performance metrics for acceptance, a table cannot be fully constructed.

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

    The document states: "Nonclinical testing was performed to show that the subject Black Diamond Navigation Instruments are substantially equivalent to the predicate device." However, it does not specify the sample size used for the test set or the data provenance (e.g., country of origin, retrospective/prospective).

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

    The document does not provide information on the number of experts used to establish ground truth or their qualifications. The testing mentioned is non-clinical, suggesting that expert human assessment in a clinical context for ground truth may not have been the primary method.

    4. Adjudication Method for the Test Set

    The document does not specify an adjudication method for the test set.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

    The document explicitly states: "No clinical studies were performed." Therefore, an MRMC comparative effectiveness study involving human readers with and without AI assistance was not conducted.

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

    The device is a set of "Navigation Instruments" used with the Medtronic Stealth Station System. This implies it's a tool for surgeons, not a standalone AI algorithm. The document mentions "Accuracy testing" and "Performance testing" among the non-clinical tests. While these tests evaluate the device's inherent capabilities (e.g., how accurately it tracks, how it performs mechanically), they are likely evaluating the instrument's standalone performance within the context of the navigation system, rather than an AI algorithm's standalone performance. The text does not explicitly refer to an "algorithm only" standalone performance study.

    7. The Type of Ground Truth Used

    The document does not explicitly state the type of ground truth used for the non-clinical testing. Given that the device is a navigation instrument for surgery, "Accuracy testing" would likely compare the instrument's reported position/orientation against a known, precise physical reference (e.g., measured by a coordinate measuring machine or similar highly accurate metrology equipment). Such a ground truth would be objective, physical measurements rather than expert consensus, pathology, or outcomes data.

    8. The Sample Size for the Training Set

    The document does not mention a training set sample size. This further supports the interpretation that the device is a physical instrument rather than a machine learning algorithm that undergoes a training phase.

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

    Since no training set is mentioned (as the device is not an AI algorithm requiring one in the traditional sense), this information is not applicable and not provided.
