    Intended Use

    NEOTIS Plate is intended to be used in conjunction with bone screws to provide fixation following Proximal Tibial Opening wedge osteotomies.

    Device Description

    The NEOTIS plate is designed for medial approach High Tibial Osteotomy stabilization. Anatomically shaped, thin and short, the NEOTIS plate enables minimally invasive surgery. The changes brought by the NEOTIS plate are as follows (vs. OTIS-C Plus plate):

    • The proximal temporary screw is replaced with a pin that offers a simpler and faster placement of the plate. The area of the cortical bone drilled through the process is also reduced.
    • The distal temporary screw is replaced with an AO screw in order to maintain compression. The compression will be maintained by the 4 permanent 6.5 mm screws (OTIS screws).
    AI/ML Overview

    The provided documentation describes a traditional 510(k) submission for the NEOTIS Plate and Screws, a medical device for bone fixation. Here's a breakdown of the acceptance criteria and the study information as extracted from the text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria TypeAcceptance CriteriaReported Device Performance
    Mechanical PropertiesNot explicitly stated as acceptance criteria, but implied to be equivalent to the predicate device."The mechanical properties are the same as for the previous OTIS-C Plus"
    Placement Process (Temporary Screw/Pin)Improved ease and speed of placement, reduced drilled cortical bone area."The proximal temporary screw is replaced with a pin that offers a simpler and faster placement of the plate. The area of the cortical bone drilled through the process is also reduced."
    Compression Maintenance (Distal Screw)Compression to be maintained."The distal temporary screw is replaced with an AO screw in order to maintain compression. The compression will be maintained by the 4 permanent 6.5 mm screws (OTIS screws)."
    Substantial EquivalenceDemonstrate that the modified NEOTIS plate is as safe, as effective, and performs as safely and effectively as its predicate device."Verification and validation tests demonstrate that modified the NEOTIS plate is as safe, as effective, and performs as safely and effectively as its predicate device."
    Confirmation of Compression (Cadaver Study)Not explicitly stated as an acceptance criterion, but the cadaver study's purpose was to confirm this."Non-clinical performance testing includes a cadaver study that confirms the level of compression induced during the placement of the plate."

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

    • Sample Size for Test Set: Not explicitly stated. The document mentions a "cadaver study" but does not provide details on the number of cadavers or specimens used.
    • Data Provenance: The cadaver study is implied to be laboratory-based (non-clinical performance testing). The document does not specify the country of origin for the cadaver data, nor does it explicitly state if it was retrospective or prospective, though "non-clinical performance testing" typically implies prospective experimental testing.

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

    • The documentation does not provide information about experts establishing ground truth for the cadaver study. The study appears to be a mechanical performance test rather than one requiring clinical interpretation by experts to establish ground truth.

    4. Adjudication Method for the Test Set

    • Not applicable/Not mentioned. The study described is a non-clinical performance test, not a study involving human interpretation with adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    • No, an MRMC comparative effectiveness study was not done. The device is hardware (plate and screws), not an AI algorithm or diagnostic tool that would typically undergo an MRMC study.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    • No, this is not applicable. The device is a physical medical implant, not an algorithm.

    7. The Type of Ground Truth Used

    • For the cadaver study, the "ground truth" was the level of compression induced by the device during placement. This is a direct physical measurement/observation in a controlled experimental setting, not expert consensus, pathology, or outcomes data in the clinical sense.

    8. The Sample Size for the Training Set

    • Not applicable. The device is not an AI/ML algorithm that requires a training set.

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

    • Not applicable. The device is not an AI/ML algorithm.
