    AI/ML Overview

    This is a 510(k) premarket notification for a medical device, which seeks to demonstrate substantial equivalence to previously cleared devices. Therefore, the information provided focuses on comparative data rather than a standalone clinical study with acceptance criteria in the same manner as a de novo or PMA submission might require.

    However, based on the provided text, we can infer some "acceptance criteria" related to magnetic resonance compatibility and how the study "proves" the device meets them.

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Inferred from ASTM Standards)Reported Device Performance
    Magnetically Induced Torque: Device should exhibit acceptable levels of torque in an MR environment (ASTM F2213)."Results demonstrated compatibility conditions of the subject devices in the MR environment." (Implies acceptable levels were met.)
    Magnetically Induced Displacement Force: Device should exhibit acceptable levels of displacement force in an MR environment (ASTM F2052)."Results demonstrated compatibility conditions of the subject devices in the MR environment." (Implies acceptable levels were met.)
    MR Image Artifacts: Device should produce acceptable levels of image artifacts (ASTM F2119)."Results demonstrated compatibility conditions of the subject devices in the MR environment." (Implies artifacts were within acceptable limits.)
    Radio Frequency Induced Heating: Device should not exhibit excessive heating in an MR environment (ASTM F2182)."Results demonstrated compatibility conditions of the subject devices in the MR environment." (Implies heating was within acceptable limits.)

    Explanation: The "acceptance criteria" here are indirectly established by the selection of specific ASTM standards for magnetic resonance compatibility. The study "proves" the device meets these criteria by performing tests according to these standards and reporting that the "results demonstrated compatibility conditions." While the exact quantitative thresholds are not provided in this summary, the FDA's clearance implies that the performance met the requirements set by these recognized standards for MR safety.


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

    • Sample Size for Test Set: Not specified. The document states that "non-clinical testing was conducted in alignment with the following standards." This usually means a set of representative devices or components are tested, but the specific number is not provided in this summary.
    • Data Provenance: The nature of the tests (magnetic resonance compatibility) indicates laboratory testing of the devices themselves, rather than human subject data. Therefore, "country of origin of the data" and "retrospective or prospective" do not directly apply in the traditional sense of clinical studies. The tests were performed to demonstrate that the device materials and design are safe within an MR environment.

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

    This submission is for device clearance based on non-clinical (laboratory) testing for MR compatibility. Therefore, there were no experts used to establish ground truth for a test set in the clinical sense. The "ground truth" is governed by the objective measurements defined by the ASTM standards for MR compatibility.


    4. Adjudication Method for the Test Set

    Not applicable. As this is non-clinical laboratory testing, there is no adjudication method involving human interpretation or consensus. The data points are quantitative measurements against predefined ASTM standard limits.


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

    No. An MRMC comparative effectiveness study was not done. This type of study is relevant for assessing the impact of AI on diagnostic performance with human readers, which is not the purpose of this submission. This submission is for the clearance of physical medical devices (spinal systems) and their magnetic resonance compatibility labeling.


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

    No. A standalone algorithm-only performance study was not done. This submission concerns physical medical devices and their MR compatibility, not an algorithm.


    7. The Type of Ground Truth Used

    The "ground truth" for the non-clinical tests was defined by the specifications and limits within the cited ASTM standards (ASTM F2213, ASTM F2052, ASTM F2119, ASTM F2182) for magnetic resonance compatibility. These standards outline methodologies and acceptable thresholds for torque, displacement force, image artifacts, and heating.


    8. The Sample Size for the Training Set

    Not applicable. There is no "training set" in the context of this 510(k) submission, as it relates to physical device testing for MR compatibility, not machine learning or AI algorithm development.


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

    Not applicable. As there is no training set, there is no ground truth to establish for it.

    • Sample Size: Not explicitly stated in this summary. For mechanical testing per ASTM standards, specific sample sizes are prescribed, but the exact number of screws/constructs tested is not given here.
    • Data Provenance: Not applicable in the context of clinical data. This refers to laboratory-based mechanical testing.

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

    Not applicable. Ground truth in this context refers to established mechanical testing standards and the comparison to predicate devices, not expert human interpretation of data for an AI.

    4. Adjudication Method for the Test Set

    Not applicable. This is mechanical testing against engineering standards.

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

    No. This is not an AI/diagnostic imaging device.

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

    Not applicable. This is a physical medical implant, not an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for this device is based on established ASTM mechanical testing standards (F1717, F543) and the performance of existing, legally marketed predicate devices. The goal is to show substantial equivalence, meaning it performs at least as well as, if not better than, comparable devices already on the market.

    8. The Sample Size for the Training Set

    Not applicable. There is no "training set" for this type of mechanical device.

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

    Not applicable. There is no "training set."

    Intended Use

    The EXPEDIUM Spine System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine.

    The EXPEDIUM™ Spine System is intended for noncervical pedicle fixation and nonpedicle fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion in skeletally mature patients.

    Device Description

    The subject EXPEDIUM Spine System components consist of 4.5mm and 6.35mm rods and are available in various geometries and sizes.

    AI/ML Overview

    The provided text describes the EXPEDIUM Spine System, a medical device intended for spinal immobilization and stabilization. However, it does not contain specific acceptance criteria, detailed study designs, or performance metrics in a way that would allow for a complete answer to your request regarding acceptance criteria and a study proving the device meets them.

    The document is a 510(k) summary and FDA clearance letter, which primarily focuses on demonstrating substantial equivalence to predicate devices, rather than presenting a detailed performance study against pre-defined acceptance criteria.

    Here's a breakdown of what can be gleaned and what is missing, structured as requested:

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

    Acceptance CriteriaReported Device Performance
    Not Explicitly Stated"Performance data per ASTM F 1717 were submitted to characterize the subject EXPEDIUM™ Spine System components addressed in this notification."

    Explanation: The document states that "Performance data per ASTM F 1717 were submitted." ASTM F 1717 is a standard specification for spinal implant constructs in vitro, likely involving mechanical testing (e.g., fatigue, static strength). However, the specific acceptance criteria (e.g., "must withstand X cycles at Y load," or "static strength must exceed Z N-m") and the device's measured performance against those criteria are not provided in this summary. The summary confirms that data was submitted to characterize the device, implying that a study was conducted, but it does not present the results or the pass/fail thresholds.

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

    • Sample Size: Not specified for any test set. The ASTM F 1717 standard would typically define the number of constructs to be tested, but this detail is not present in the summary.
    • Data Provenance: Not specified. It's an in-vitro mechanical test, so "country of origin of data" is less relevant than for clinical data, but the location of the testing facility is not provided. Retrospective or prospective classification is not applicable to an in-vitro mechanical test.

    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)

    • This question is not applicable to the device and performance data described. The device is a spinal implant system, and the performance data cited (ASTM F 1717) refers to mechanical properties, not diagnostic performance or clinical outcomes requiring expert interpretation to establish ground truth.

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

    • Not applicable. As the performance data pertains to mechanical testing (ASTM F 1717), there is no need for expert adjudication. Mechanical tests follow standardized protocols.

    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

    • Not applicable. This device is a spinal implant system, not a diagnostic imaging or AI-assisted device. Therefore, MRMC studies involving human readers and AI assistance are not relevant.

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

    • Not applicable. This device is a physical spinal implant system, not a software algorithm.

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

    • Not applicable in the typical sense of ground truth for diagnostic devices. For mechanical testing (ASTM F 1717), the "ground truth" is established by the physical properties and behavior of the device components under controlled test conditions, measured against the specifications of the standard. There is no expert consensus, pathology, or outcomes data used to establish "ground truth" for this type of performance assessment.

    8. The sample size for the training set

    • Not applicable. There is no "training set" for a physical medical device undergoing mechanical performance testing. This concept applies to machine learning algorithms.

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

    • Not applicable. (See point 8).

    Summary of available information:

    The 510(k) summary indicates that the EXPEDIUM Spine System is a Class III medical device intended for spinal immobilization and stabilization. It states that "Performance data per ASTM F 1717 were submitted to characterize the subject EXPEDIUM™ Spine System components." This implies that a study was conducted to evaluate the mechanical properties of the device according to the ASTM F 1717 standard. However, the specific details of this study, including the acceptance criteria, the actual performance results, sample sizes, or any form of "ground truth" that would be applicable to diagnostic or AI devices, are not present in the provided document. The document primarily serves to demonstrate substantial equivalence to previously cleared predicate devices, allowing it to proceed to market without a full PMA.

    Intended Use

    The Savannah Lumbar Percutaneous Stabilization System (SLPSS) is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the lumbar and/or sacral spine, specifically as follows:

    When used as a pedicle screw fixation system of the posterior lumbar spine in skeletally mature patients, the SLPSS is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment. (2) fracture, (3) dislocation, (4) spinal tumor, and/or (5) failed previous fusion (pseudarthrosis).

    In addition, when used as a pedicle screw fixation system, the SLPSS is indicated for skeletally mature patients: (a) having severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (d) who are having the device removed after the development of a solid fusion mass.

    The Savannah Lumbar Percutaneous Stabilization System (SLPSS) is also intended to provide immobilization and stabilization of the spinal segments of the lumbar and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment.

    Device Description

    The Savannah Lumbar Percutaneous Stabilization System is comprised of a variety of pedicle screws sizes, couplers, a ball swivel, rods and locking nuts that can be uniquely fitted for each individual case. All implantable components are manufactured from medical grade titanium alloy (Ti6Al4V-Eli).

    AI/ML Overview

    The provided text is a 510(k) summary for the Savannah Lumbar Percutaneous Stabilization System (SLPSS). It describes the device, its indications for use, and how it demonstrates substantial equivalence to predicate devices. However, the document does not contain information about acceptance criteria or a study that specifically proves the device meets such criteria.

    Instead, the document states:

    "The pre-clinical testing performed indicated that the Savannah Lumbar Percutaneous Stabilization System is substantially equivalent to predicate devices."

    This implies that the device's performance was compared to existing, legally marketed devices (predicates) rather than against specific, predefined acceptance criteria through a standalone clinical or performance study with detailed metrics. The regulatory pathway chosen, a 510(k), relies on demonstrating "substantial equivalence" to a predicate device, which often involves comparing technical characteristics and performance data to show that the new device is as safe and effective as the predicate.

    Therefore, for your request, the following information is largely not present in the provided text:

    1. A table of acceptance criteria and the reported device performance: No specific acceptance criteria or performance metrics are listed.
    2. Sample size used for the test set and the data provenance: Not mentioned.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned.
    4. Adjudication method for the test set: Not mentioned.
    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs. without AI assistance: Not applicable, as this is a surgical implant, not an AI-assisted diagnostic device.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable for a surgical implant.
    7. The type of ground truth used: Not applicable, as it's not a diagnostic device.
    8. The sample size for the training set: Not mentioned.
    9. How the ground truth for the training set was established: Not mentioned.

    Summary of available information:

    • Device Name: Savannah Lumbar Percutaneous Stabilization System (SLPSS)
    • Regulatory Pathway: 510(k) Premarket Notification (K072116)
    • Claim of Performance: "The pre-clinical testing performed indicated that the Savannah Lumbar Percutaneous Stabilization System is substantially equivalent to predicate devices."

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the Moss Miami Spinal System Polyaxial Screws, a medical device. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through clinical trials with specific acceptance criteria and performance data.

    Therefore, the document does not contain the requested information regarding acceptance criteria, device performance tables, study details (sample sizes, data provenance, expert involvement, adjudication, MRMC studies, standalone performance), or ground truth establishment.

    Instead, the submission relies on the established safety and effectiveness of predicate devices. The FDA determines "substantial equivalence" based on factors like:

    • Intended Use: The Moss Miami Spinal System Polyaxial Screws share similar intended uses with the predicate devices.
    • Technological Characteristics: The device is described as Polyaxial Screws designed to accept a 5.5mm rod, which is compared to existing Moss Miami Spinal System components.
    • Performance Data: While not explicitly detailed, 510(k) submissions typically include non-clinical performance testing (e.g., mechanical testing, biocompatibility) to demonstrate that the new device performs as safely and effectively as the predicate device and meets established engineering standards. However, these specific test results are not part of this summary document.

    In summary, this document is a regulatory approval notice based on substantial equivalence, not a study report demonstrating acceptance criteria and device performance as would be found in a clinical trial.

    Intended Use

    When used as an anterior, thoracic/lumbar screw fixation system, the Centaur™ Spinal System is intended to treat deformities of curvature (i.e. scoliosis, kyphosis and/or lordosis), fracture, tumor, spinal stenosis, spondylolisthesis, a previously failed fusion surgery or degenerative disc disease (i.e.discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies).
    Warning: This device is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

    Device Description

    The Centaur "Spinal System is a spinal fixation device for the noncervical spine. All components are manufactured from ISO 5832/3 (ASTM F-136-96) titanium alloy (Ti6Al-4V ELI). The system consists of primary and secondary screws, rods, lateral connectors, plates, and accessories.

    Bone Screws: There are two different types of screws in the Centaur" Spinal System. They are primary and secondary screws. The head of the primary screw receives the connectors and the tightening screws for both the plate and rod systems. The head of the secondary screw is shaped to allow for a 5° angulation in all directions. Both the primary and secondary screws are threaded at the distal end. The distal aspect of the screws feature cancellous bone threads. Screws are available in two diameters: 5.5mm and 7mm, and in lengths of 25mm (in 5mm increments).

    Rods: There are two types of spinal rods used in the Centaur" Spinal System. The first type is 4mm in diameter and the second type is 6mm in diameter. Both types range in length from 60mm to 160mm in 10mm increments. Rods are slipped into the rod connector and ball ring and are tightened down by rod locking screws. The rod connectors have a specific anatomic shape. They can be adapted to both the antero-posterior and craniocaudal shape of the lateral vertebra. A ball ring allows for a +1-15 angulation of the 6mmod. The posterior aspect of the rod system uses the larger rods, and this is the aspect that has the higher profile when implanted. The anterior aspect of the rod system uses the smaller rods which have the lower profile of the implant.

    Plates: There are three types of plates used in the Centaur" Spinal System. All three are L-shaped. The first type, straight plates, range from 30mm in length in 10mm increments The second type, lordotic plates, range from 60mm to 90mm in length in 10mm increments. The third type, kyphotic plates, range in length from 50mm in 10mm increments. The plate system is not monoblock, thereby allowing more flexibility and greater opportunity for compression which aids fusion. Plates are assembled to the screws through the use of a plate connector and are locked down by set screws.

    AI/ML Overview

    Here's an analysis of the provided text regarding the Centaur™ Spinal System's acceptance criteria and studies, organized according to your requested information.

    It's important to note that the provided 510(k) summary (K994347) is for a spinal fixation system, not a device that involves AI, diagnostic imaging, or human reader performance. Therefore, many of your requested items, which are typical for AI/diagnostic device submissions, are not applicable to this medical hardware submission. The information provided heavily emphasizes mechanical and material equivalence.

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

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

    This information is not applicable to this type of device submission. The "test set" in this context refers to mechanical testing of the physical device components, not a dataset of patient images or clinical outcomes. The submission focuses on device equivalence through material specifications and mechanical performance data, not clinical data provenance.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    This information is not applicable. "Ground truth" in this context would refer to expert consensus on clinical findings or pathology, which is not relevant for a mechanical spinal implant. The "ground truth" for mechanical testing is typically engineering specifications and established test methods.

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

    This information is not applicable. Adjudication methods are used for disagreements in human reader assessments, which are not part of this device's evaluation.

    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

    This information is not applicable. This is a spinal hardware system, not an AI or diagnostic imaging device that involves human readers interpreting cases.

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

    This information is not applicable. This is a physical medical device, not an algorithm.

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

    The "ground truth" in this context is based on mechanical engineering standards and established material properties. The device's performance is compared against the known performance characteristics of the predicate device and the specified material (Ti6Al-4V ELI).

    8. The sample size for the training set

    This information is not applicable. The concept of a "training set" applies to machine learning models, not to the development and testing of a physical spinal implant.

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

    This information is not applicable, as there is no "training set" in the context of this device.


    Summary of the Study that Proves the Device Meets Acceptance Criteria:

    The study proving the Centaur™ Spinal System meets the acceptance criteria is described as a comparison to a predicate device and mechanical testing.

    The acceptance criterion is primarily demonstrating substantial equivalence to the predicate device, the MOSS Miami Spinal System (K983583), in terms of intended use, basic design concepts, and material.

    The study presented to establish this equivalence involved:

    • Statement of Technological Comparison: The submission explicitly states that the Centaur™ Spinal System shares the same intended use and basic design concepts as the MOSS Miami Spinal System.
    • Material Equivalence: Both systems use ISO 5832/3 (ASTM F-136-96) titanium alloy (Ti6Al-4V ELI), which has a "long and successful history of use in orthopedic implant surgery."
    • Mechanical Testing: The crucial evidence provided is that "Fatigue and static testing demonstrates the comparable mechanical and endurance properties of these components" when compared to the predicate device. While specific numbers for fatigue and static loads are not detailed in the summary, the statement indicates that such tests were performed and showed comparable results.

    In essence, the "study" for the Centaur™ Spinal System was a bench-top engineering evaluation demonstrating material compatibility and equivalent mechanical performance to a previously cleared device. It's a technical dossier proving physical and functional equivalence, rather than a clinical study evaluating diagnostic accuracy or treatment outcomes.

    Intended Use

    When used as a posterior, noncervical hook, and/or sacral/iliac screw fixation system, or as an anterior, thoracic/lumbar screw fixation system, the Moss Miami Spinal system is intended to treat scoliosis, kyphosis and lordosis, fracture, loss of stability due to tumor, spinal stenosis, spondylolisthesis, a previously failed fusion surgery or degenerative disc disease (i.e. discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies).

    When used as a pedicle screw fixation system of the noncervical spine in skeletally mature patients, the Moss Miami Spinal system is indicated for degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis).

    The Moss Miami spinal system is also indicated for pedicle screw fixation in skeletally mature patients with severe spondylolisthesis (Grades 3 and 4) at the L5-S1 vertebral joint, having fusions with autogenous bone graft, with the device fixed or attached to the lumbar and sacral spine (levels of pedicle screw fixation are L3 -S1), and for whom the device system is intended to be removed after solid fusion is attained.

    Device Description

    The Moss Miami 6.35mm Polyaxial screws described in this submission are modifications of the previously cleared Moss Miami Polyaxial Screws. The head portion of the screw has been increased to allow the placement of a 6.35mm (1/4 inch) rod. The modified screws are available in the same thread diameters and lengths as the existing screws, namely 6.0mm, 7.0mm, and 8.0mm diameters and 30mm to 55mm lengths.

    The 6.35mm polyaxial screws are manufactured from either implant grade titanium alloy or stainless steel that conform to ASTM standards F-136 and F-138, respectively.

    AI/ML Overview

    The provided text describes specific details about a medical device (Moss Miami 6.35mm Polyaxial Screw) that has received 510(k) clearance, but it does not contain information related to software or AI-based devices. Therefore, the requested information regarding acceptance criteria, study details (sample sizes, ground truth, expert qualifications, adjudication methods, MRMC studies, standalone performance), and training set information is not available in the provided text.

    The document focuses on the mechanical and material characteristics of a pedicle screw modification and its substantial equivalence to previously cleared devices. It states:

    • Device Description: The Moss Miami 6.35mm Polyaxial screws are modifications of previously cleared Moss Miami Polyaxial Screws. The head portion has been increased to allow for a 6.35mm (1/4 inch) rod. They come in 6.0mm, 7.0mm, and 8.0mm diameters and 30mm to 55mm lengths, made from implant-grade titanium alloy or stainless steel conforming to ASTM standards F-136 and F-138 respectively.
    • Testing: "Testing was presented to evaluate the performance characteristics of the modified polyaxial screws. Specific tests of the construct included static tests in compression bending and torsion, and fatigue testing in compression bending."
    • Substantial Equivalence Basis: "The substantial equivalence of the modified Polyaxial screws is based on an equivalence in intended use, materials, design, and relative indications and contraindications to the existing Moss Miami Polyaxial Screw System."

    Without information on the specific acceptance criteria for these mechanical tests (e.g., minimum loads, cycles to failure, maximum deformation), or the detailed results of these tests, it's impossible to fill out the requested table or answer most of the questions. The document only states that "testing was presented to evaluate the performance characteristics," implying the data was submitted to the FDA for review, but the actual data and acceptance criteria are not included in this summary.

    Therefore, I cannot provide the requested table and detailed study information as it pertains to AI/software performance acceptance criteria.
