    AI/ML Overview

    The provided document is a 510(k) Premarket Notification from the FDA for the Whistler Modular Pedicle Screw System. It describes the device, its indications for use, and a comparison to predicate devices, but it does not contain information regarding an AI/ML-driven device or studies proving its performance against acceptance criteria in the context of diagnostic accuracy, image analysis, or similar AI-related applications.

    Instead, this document focuses on a physical medical device (pedicle screw system) and its mechanical performance testing to demonstrate substantial equivalence to existing devices. The performance data listed (Static Axial Compression Bending, Static Torsion, Dynamic Axial Compression Bending, Static A-P load) are standard mechanical tests for spinal implants, not AI performance metrics.

    Therefore, I cannot fulfill the request to describe acceptance criteria and a study that proves a device meets acceptance criteria in an AI/ML context using the provided text. The document is entirely about a hardware implant.

    AI/ML Overview

    The provided text is a 510(k) summary for a medical device called the "Mont Blanc Pedicle Screw System." It describes the device, its intended use, and the basis for its substantial equivalence to previously cleared devices.

    However, the questions you've asked are about "acceptance criteria" and "study that proves the device meets the acceptance criteria" in the context of device performance, sample sizes for test and training sets, expert review, and ground truth establishment.

    Based on the provided document, the device described is a pedicle screw system, which is an orthopedic implant. For this type of device, "performance testing" typically refers to mechanical testing to ensure the device's structural integrity and durability, rather than a clinical study evaluating diagnostic accuracy or algorithmic performance as would be the case for an AI/ML device.

    Therefore, the information you are requesting about

    1. Acceptance criteria and reported device performance (in terms of sensitivity, specificity, etc.)
    2. Sample sizes for test set and data provenance
    3. Number of experts and qualifications for ground truth
    4. Adjudication method
    5. MRMC comparative effectiveness study
    6. Standalone algorithm performance
    7. Type of ground truth (pathology, outcomes data, etc.)
    8. Sample size for training set
    9. How training set ground truth was established

    is not present in the provided 510(k) summary.

    The document states:

    • Performance Testing: "Testing performed indicates the Mont Blanc Pedicle Screw System is substantially equivalent to predicate devices. Testing included mechanical testing per ASTM F1717, including static and dynamic compression bending and static torsion." This refers to laboratory-based mechanical tests, not clinical studies.
    • Acceptance Criteria: These would be defined by the ASTM F1717 standard for pedicle screw systems (e.g., minimum loads for static and dynamic failure, or deformation limits) but are not explicitly detailed in the summary.
    • Device Performance: The documented performance is that it met the requirements of ASTM F1717, showing it is "substantially equivalent" to predicate devices. Specific numerical results from these tests (e.g., actual breaking strength values) are not provided in this summary.

    In summary, this document does not contain the type of information you are asking for, which is typically found in submissions for AI/ML-driven diagnostic devices or devices that rely on complex data analysis and expert interpretation. It describes a traditional, passive mechanical implant.

    Intended Use

    When used as a pedicle screw fixation system, Aesculap's Spine System® Evolution is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine: degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis).

    It is also intended for the treatment of severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra in skelatally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine with removal of the implants after the attainment of a solid fusion. Levels of pedicle screw fixation for this indication are from L3-S1.

    When used as a non-pedicle screw system, Aesculap's Spine System® Evolution is indicated for use in patients with degenerative disc disease (defined as back pain of discongenic origin with degeneration of the disc confirmed by history and radiographic studies), kyphosis, spondylolisthesis, neurological scoliosis, spine tumors and fractures. It is intended for posterior fixation from levels T1 through S1.

    Device Description

    Spine System® Evolution is a multiple component system comprised of a variety of single use devices that allow the surgeon to build a spinal implant construct in order to stabilize the thoracic and lumbar vertebrae and promote spinal fusion. The additional components presented in this submission are pedicle, laminar, thoracic and counter hooks. The spinal implants are manufactured from titanium alloy (Ti6Al4V) in accordance to ISO 5832/III. The specialized instrumentation used to implant and explant the Spine System® Evolution implants are made from surgical grade stainless steel in accordance to ISO 7153/1.

    AI/ML Overview

    The provided document is a 510(k) summary for the Aesculap Spine System® Evolution Additional Components, submitted in 1998. It primarily focuses on demonstrating substantial equivalence to pre-existing spinal fixation systems rather than proving device performance against specific acceptance criteria through a clinical study or even extensive standalone performance testing as would be expected for an AI/ML device.

    Therefore, many of the requested elements for an AI/ML device's acceptance criteria and study proving performance are not applicable or not present in this type of regulatory submission for a medical device from that era.

    Here's an attempt to answer based on the provided document, highlighting what is (and isn't) present:


    Acceptance Criteria and Study to Prove Device Performance (Aesculap Spine System® Evolution Additional Components)

    This submission demonstrates substantial equivalence of the Aesculap Spine System® Evolution Additional Components to previously marketed spinal implant systems. The "performance data" presented is primarily mechanical testing, typical for hardware medical devices, rather than a study proving performance against acceptance criteria as might be expected for an AI/ML device.

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Established through Predicate Device Equivalence)Reported Device Performance (from mechanical testing)
    Material Composition: Titanium alloy (Ti6Al4V) in accordance with ISO 5832/III.The implants "are manufactured from titanium alloy (Ti6Al4V) in accordance to ISO 5832/III."
    Mechanical Performance: Performance equivalent to predicate devices when subjected to spinal implant construct testing.Subjected to mechanical testing according to ASTM Standard F 1717-96 (Static and Fatigue Test Methods for Spinal Implant Constructs in a Corpectomy Model). (Specific numerical results are not provided in this summary, but the implication is that it met the expected performance for such tests).
    Intended Use: Immobilization and stabilization of spinal segments as an adjunct to fusion for specific conditions (degenerative spondylolisthesis, fracture, scoliosis, etc.). Also, for severe spondylolisthesis (grades 3 and 4) of L5-S1 and as a non-pedicle screw system for degenerative disc disease, kyphosis, etc.The device is intended for these uses. The substantial equivalence argument implies it performs adequately for these indications, similar to predicate devices.
    Design and Function: Substantially equivalent in design and function to predicate devices.Aesculap believes the components are "substantially equivalent in design, material composition, function and intended use" to listed predicate devices.

    Note: For a traditional hardware device like this, "acceptance criteria" are often met by demonstrating adherence to recognized standards (like ISO for materials, or ASTM for mechanical testing) and by showing substantial equivalence to devices already legally on the market that have demonstrated safe and effective performance. Specific quantitative performance metrics for clinical outcomes against predefined thresholds are not typically part of a 510(k) summary for such devices.

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

    • Sample Size for Test Set: Not applicable in the context of an AI/ML device's test set. For mechanical testing, the "sample size" would refer to the number of components or constructs tested in a lab setting. This information (specific number of samples tested for ASTM F 1717-96) is not provided in the summary.
    • Data Provenance: Not applicable in the context of clinical data provenance for an AI/ML device. The "performance data" refers to in vitro mechanical testing.

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

    Not applicable. This device is a physical spinal implant system, not a diagnostic AI/ML device requiring expert-established ground truth for a test set.

    4. Adjudication Method for the Test Set

    Not applicable. No expert adjudication process is described for this type of mechanical device.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No. An MRMC study is relevant for AI/ML diagnostic tools that impact human reader performance. This is a spinal implant, so such a study was not performed or described.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    Not applicable. This device is a physical implant, not an algorithm. The "standalone performance" is related to its mechanical integrity, which was assessed via in vitro ASTM F 1717-96 testing. The results of this testing are not detailed in the summary, simply that it was performed.

    7. Type of Ground Truth Used

    Not applicable in the context of typical AI/ML ground truth.
    For this device, "ground truth" would be established by:

    • Adherence to material standards (ISO 5832/III).
    • Results of mechanical testing (ASTM F 1717-96) demonstrating structural integrity and fatigue life, often compared against specified limits or predicate device performance.
    • The established safety and effectiveness track record of the predicate devices to which it claims substantial equivalence.

    8. Sample Size for the Training Set

    Not applicable. This is a physical device, not an AI/ML algorithm requiring a training set.

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

    Not applicable. As above, no training set for an AI/ML algorithm.
