    AI/ML Overview

    The provided text describes the 510(k) premarket notification for the "OsteoWedge II Open Wedge Bone Locking Plate System." This document primarily focuses on demonstrating substantial equivalence to predicate devices based on non-clinical performance testing. It does not describe an AI/ML-based medical device. Therefore, many of the requested categories related to AI/ML device evaluation (like sample size for test set, data provenance, number of experts, adjudication method, MRMC studies, standalone performance, training set details) are not applicable to this submission.

    Here's a summary of the information that is available in the provided text, structured to address the relevant points where possible:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaReported Device Performance
    Demonstrate substantial equivalence to predicate devicesNon-clinical testing was performed to demonstrate the change of the plate geometry is substantially equivalent to other predicate devices. OsteoWedge II Open Wedge Bone Locking Plate System is shown to be substantially equivalent to legally marketed predicate devices.
    Static and dynamic four-point bending testing per ASTM F382-99(2008)Testing was performed as specified. (Specific quantitative results or pass/fail thresholds against acceptance criteria are not provided in this summary document, but the conclusion is that it demonstrated substantial equivalence).

    2. Sample size used for the test set and the data provenance

    Intended Use

    The GraMedica opti-Toe Device is indicated for reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe. The GraMedica opti-Toe components are to be cemented in place and assembled for reconstruction of the toe. Patients should protect their weight-bearing only until soft tissue healing has occurred.

    Device Description

    The GraMedica opti-Toe is comprised of two mated components (proximal and middle phalangeal) which join together to form a single intramedullary fixation unit. The implants are offered in two sizes, small and large, and the middle phalangeal component is offered with and without a 10 degree angulation.

    AI/ML Overview

    The document provided is a 510(k) premarket notification from the FDA for a medical device called "opti-Toe". This type of document focuses on establishing substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria through a clinical study. Therefore, the information typically requested in your prompt regarding acceptance criteria, sample sizes, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance for AI/ML devices is not present in this regulatory filing.

    However, I can extract the non-clinical performance testing information that was conducted to support the substantial equivalence claim for the opti-Toe device.

    Here's a summary of the non-clinical performance testing performed:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document does not explicitly state acceptance criteria in a numerical or categorical format for the non-clinical tests. Instead, the testing was performed to demonstrate the device's functional integrity and similarity to predicate devices. The "reported device performance" is the successful completion of these tests.

    Acceptance Criteria CategoryReported Device Performance
    Clinical Ease of UseSuccessfully demonstrated via Cadaveric Simulated Use Study, Assembly Force, and Disassembly Force measurements.
    Mechanical PerformanceSuccessfully evaluated via Static and Dynamic Bending tests.

    2. Sample Sizes Used for the Test Set and Data Provenance:

    • Cadaveric Simulated Use Study: The document does not specify the number of cadavers used.
    • Assembly/Disassembly Force, Static/Dynamic Bending: The document does not specify the number of devices or iterations tested for these mechanical evaluations.
    • Data Provenance: The testing was non-clinical (laboratory and cadaveric) and conducted for regulatory submission purposes. No information on country of origin of data or retrospective/prospective nature is applicable as it's not a clinical trial with patient data.

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

    Not applicable. For non-clinical tests like mechanical and cadaveric studies, "ground truth" as it relates to expert consensus on clinical findings is not established. The "ground truth" for these tests would be the measured physical properties and observations of functionality.

    4. Adjudication Method for the Test Set:

    Not applicable. Adjudication methods are typically for clinical trials or expert label review, not for non-clinical mechanical or cadaveric testing.

    5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done:

    No. An MRMC study is a type of clinical study generally used for diagnostic devices involving human readers evaluating medical images. This document describes a K-wire equivalent fixation device and its non-clinical testing, so an MRMC study was not conducted or applicable.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:

    Not applicable. This device is a physical medical implant (a toe fixation device), not an algorithm or AI system.

    7. The Type of Ground Truth Used:

    For the non-clinical tests:

    • Cadaveric Simulated Use Study: "Ground truth" was the observed functionality and ease of use in a cadaveric model.
    • Mechanical Testing (Assembly/Disassembly Force, Static/Dynamic Bending): "Ground truth" was the objective measurements of force and bending properties according to established engineering standards or internal protocols, likely compared against predicate device performance or relevant industry standards for similar devices.

    8. The Sample Size for the Training Set:

    Not applicable. This is not an AI/ML device; therefore, there is no "training set."

    9. How the Ground Truth for the Training Set was Established:

    Not applicable. As there is no training set for an AI/ML device, this question is not relevant.

    Intended Use

    HyProCure II (HYP II and HYP IIs) is an implant stabilization device used in the treatment of hyperpronating instability of the hindfoot. The implant is designed to stabilize the talus to prevent excessive anterior, and/or plantarflexion of the talus, while allowing normal talotarsal joint motion.

    Device Description

    The HyProCure II is an implant which stabilizes the talus on the tarsal mechanism. The system consists of an implant designed to be inserted into the sinus tarsi and corresponding instrumentation to facilitate insertion.

    AI/ML Overview

    This document is a 510(k) summary for the HyProCure II device. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study with specific acceptance criteria and detailed device performance metrics. Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes, expert qualifications, and ground truth establishment is not present in the provided text.

    Here is an attempt to address the points based only on the provided text, with clear indications where the information is missing:

    1. A table of acceptance criteria and the reported device performance

    Based on the document, direct acceptance criteria and reported device performance in the context of a formal study with quantitative metrics are not provided. The document states:

    Acceptance Criteria (Implied)Reported Device Performance

    No specific performance data (e.g., in terms of degrees of motion, force resistance, or patient outcome scores) is provided in this summary. The conclusion states it is "safe and effective for its intended use" based on this comparison.

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Sample Size for Test Set: Not applicable/Not provided. The document explicitly states: "Non-clinical data was not necessary to show substantial equivalence." This implies a performance study (with a test set) comparing the device to performance criteria was not conducted for this 510(k) submission.
    • Data Provenance: Not applicable/Not provided.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    • Not applicable/Not provided, as no traditional test set requiring expert ground truth was mentioned.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not applicable/Not provided, as no traditional test set requiring expert adjudication was mentioned.

    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 MRMC study was mentioned. The device, HyProCure II, is a physical implant (sinus tarsi implant), not an AI-powered diagnostic tool, so such a study would not be relevant.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    • Not applicable. The device is a physical implant, not an algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • Not applicable/Not provided, as no traditional test set requiring ground truth was mentioned. The basis for safety and effectiveness is substantial equivalence to a legally marketed predicate device.

    8. The sample size for the training set

    • Not applicable/Not provided. The device is a physical implant and does not involve machine learning algorithms that require a training set.

    9. How the ground truth for the training set was established

    • Not applicable/Not provided, as there is no training set for this type of device.

    Intended Use

    The OsteoWedge™ Opening Wedge Bone Locking Plate System is used for adult and transitional adolescent (18 to 21 years old) patients for the purpose of stabilization and/or correction of angular deviations within an individual bone or in between two adjacent bones in the foot, such as opening wedge osteotomy for first metatarsal cuneiform joint deviations.

    Device Description

    The OsteoWedge™ Open Wedge Bone Locking Plate System consists of plates and screws and incorporates a screw-to-plate locking mechanism. The plate is attached to a prepared surface of the involved bone(s) of the foot using six (6) screws for fixation. The plates are available in six (6) wedge sizes. The fully threaded screws are available in 2 diameters, with numerous lengths.

    AI/ML Overview

    The OsteoWedge™ Opening Wedge Bone Locking System is a medical device used for stabilizing and/or correcting angular deviations in the bones of the foot. Its acceptance was based on demonstrating substantial equivalence to predicate devices, namely the Arthrex, Inc. Low Profile Plate and Screw System and the Darco International, Inc. DACRO Locking Bone Plate System.

    Here's an analysis of the acceptance criteria and study information:

    1. Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the OsteoWedge™ system were primarily based on demonstrating substantial equivalence to existing legally marketed predicate devices. This involves showing that the new device has the same intended use and technological characteristics as the predicate devices, or if it has different technological characteristics, that it does not raise different questions regarding its safety and effectiveness.

    The reported device performance is implicitly that it meets the safety and effectiveness profile equivalent to the predicate devices.

    Acceptance Criteria CategorySpecific CriteriaReported Device Performance
    Intended Use EquivalenceThe OsteoWedge™ system must have the same intended use as the predicate devices. This includes the patient population (adult and transitional adolescent patients, 18-21 years old) and the purpose (stabilization and/or correction of angular deviations within an individual bone or between two adjacent bones in the foot, such as opening wedge osteotomy for first metatarsal cuneiform joint deviations).The OsteoWedge™ system's intended use is for "adult and transitional adolescent (18 to 21 years old) patients for the purpose of stabilization and/or correction of angular deviations within an individual bone or in between two adjacent bones in the foot, such as opening wedge osteotomy for first metatarsal cuneiform joint deviations." This was deemed comparable to the predicates, which are also used for stabilization and fixation in foot bones. Although OsteoWedge has a narrower indication (foot only) compared to some predicates (hand, feet, wrist, ankles, fingers, and toes), this difference was not considered to raise new questions of safety or effectiveness.
    Technological Characteristics EquivalenceThe device should share similar technological characteristics with the predicate devices, including materials, design principles, screw-to-plate locking mechanisms, and provision as non-sterile for cleaning and sterilization. Deviations in size should be justified not to impact safety or effectiveness negatively.Materials: All devices are made of the "same materials."
    Sterilization: All devices are "provided non sterile for cleaning and sterilization prior to use."
    Function/Mechanism: All devices are for "fixation & stabilization" and incorporate a screw-to-plate locking mechanism.
    Size: The OsteoWedge™ has "slightly larger 'wedge size'" than the predicate devices, but this was justified as leading to "narrower 'indications for use'" and not raising new safety/effectiveness questions.
    Safety and EffectivenessThe device must not raise different questions regarding its safety and effectiveness compared to the predicate devices. This is typically supported by non-clinical performance testing.Non-Clinical Testing: The following tests were performed:
    • Bend Testing (Static Four Point Bending & Dynamic Four Point Bending)
    • Bending Strength
    • Torsion Testing
    • Self-Tapping Performance
    • Axial Pullout Testing
    • Insertion and Removal Testing
    • Cleaning and Sterilization Testing
      Conclusion: The submission states that "the differences between the OsteoWedge™ Opening Wedge Bone Locking Plate System and the predicate devices do not raise any questions regarding its safety and effectiveness." |

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

    The provided document does not describe a "test set" in the context of clinical data or patient samples. The submission relies on non-clinical (bench) testing to support substantial equivalence.

    • Sample Size for Test Set: Not applicable in the context of clinical data. The sample sizes would refer to the number of devices or components tested during the non-clinical mechanical and sterilization tests, but these specific numbers are not provided in the summary.
    • Data Provenance: Not applicable for clinical data. The non-clinical testing was conducted to evaluate the device's physical properties and performance against engineering standards. The location or specific context of these non-clinical tests is not detailed beyond being "performed to support substantial equivalence."

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

    This information is not applicable as the submission did not rely on clinical data, expert consensus, or ground truth established by medical experts for a "test set" to prove device performance in a diagnostic or clinical efficacy manner. The assessment was based on engineering and performance characteristics relative to predicate devices.

    4. Adjudication Method for the Test Set

    This information is not applicable as there was no clinical "test set" requiring adjudication by experts.

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

    No. The document explicitly states: "Clinical trial or testing was not required for the OsteoWedge™ Opening Wedge Bone Locking System." Since no clinical trials were done, an MRMC study was certainly not performed, and therefore, an effect size of human readers with AI assistance is not relevant.

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

    No. This device is a physical bone plate system, not an AI algorithm or diagnostic tool. The concept of "standalone performance" for an algorithm or human-in-the-loop performance is not applicable to this type of medical device.

    7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

    For the non-clinical testing, the "ground truth" refers to established engineering standards, material properties, and mechanical performance metrics (e.g., bending strength, torsion resistance, pullout strength). These are objective, measurable physical properties, not clinical outcomes or expert interpretations.

    8. The Sample Size for the Training Set

    Not applicable. This device is hardware and does not involve AI or machine learning, so there is no "training set."

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

    Not applicable. As there is no training set for an AI algorithm, this question is irrelevant to the device submission.
