    Intended Use

    When used as a cervical intervertebral body fusion device, the Biomet Intervertebral Body/VBR Fusion System ("Biomet Fusion System") is intended for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients with degenerative disc disease ("DDD") at one spinal level from the C2-C3 disc to the C7-T1 disc. DDD is defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radios. These patients should have had at least six weeks of non-operative treatment. The Biomet Cervical Intervertebral Body Fusion System is to be implanted via an anterior approach and is to be combined with supplemental fixation. Approved supplemental fixation systems include the Biomet Anterior Cervical Plate System.

    When used as a lumbar intervertebral body fusion device, the Biomet Intervertebral Body/VBR Fusion System ("Biomet Fusion System") is intended for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients with degenerative disc disease ("DD") at one or two contiguous spinal levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six months of non-operative treatment. These DDD patients may have had a previous non-fusion spinal surgery at the involved spinal level(s), and may have up to Grade 1 spondylolisthesis at the involved level(s). Implants with 14 degree lordosis or greater are only indicated from levels L2-L5 and are to be used with at least one integrated fixation screw. The Biomet Fusion System is to be combined with supplemental fixation (except as noted below). Approved supplemental fixation systems include the Biomet Spinal Fixation System. The Biomet SA standalone interbody implants, when implanted via an anterior approach and used with the integrated fixation screws, do not require use of supplement fixation.

    When used as vertebral body replacement, the Biomet Intervertebral Body/VBR Fusion System ("Biomet Fusion System") is indicated for use to replace a vertebral body that has been resected or excised due to tumor or traumalfracture. The device is intended for use as a vertebral body replacement in the thoracolumbar spine (from T1 to L5) The Biomet Vertebral Body Replacement System may also be used in the thoracolumbar spine (i.e. T1- L5) for partial replacement (i.e., partial vertebrectomy) of a diseased vertebral body resected or excised for the treatment of tumors in order to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Biomet Vertebral Body Replacement System is also indicated for treating fractures of the thoracic and lumbar spine. The Biomet Vertebral Body Replacement System is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column. For either indication the system must be used with supplemental internal fixation. Supplemental internal fixation is required to properly utilize this system.

    Device Description

    The subject Biomet Fusion System has the same or similar intended use, indications for use, technological characteristics and principles of operation as the intervertebral body fusion devices which were reclassified as explained in FDA's guidance document, "Class II Special Controls Guidance Document: Intervertebral Body Fusion Device" (June 12, 2007). The subject Biomet Fusion is substantially equivalent to the previously cleared Biomet Fusion System (K141791).

    The Biomet Fusion System is intended for use in intervertebral body fusion or vertebral body replacement. However, the implants included in this application are intended for use in lumbar intervertebral body fusion only. The subject implants are a line extension of those currently available in the Biomet Fusion System. Modifications have been made to the currently available Biomet Fusion System implants to add additional plate heights (18mm and 20mm) in both 1-hole and 2-hole configurations as well as to add a new 14degree spacer option. As a result of these new 18mm and 20mm plates and 14 degree spacers, taller cover plates, implant trials, and implant caddies were developed to correspond to the new implant sizes.

    The Biomet Fusion System implants consist of a spacer body and plates with screws for additional fixation. The spacers are made from PEEK-OPTIMA® LT1, a polyaromatic semicrystalline thermoplastic polymer (-CcH4-O-CcH4-O-CcH4-CO-), with tantalum markers. The plates and screw are made from implant grade titanium alloy (Ti-6AI-4V ELI) meeting ASTM F136-08 and ISO 5832-3. The Biomet Fusion System spacers, plates, and screws are available in a variety of sizes and configurations to accommodate anatomical variation in different vertebral levels and/or patient anatomy. The Biomet Fusion System is provided non-sterile.

    Specifically, the document does not provide:

    • A table of acceptance criteria and reported device performance.
    • Sample sizes for test sets or their data provenance.
    • The number or qualifications of experts used to establish ground truth.
    • Adjudication methods.
    • Information about multi-reader multi-case (MRMC) comparative effectiveness studies or effect sizes.
    • Details on standalone algorithm performance.
    • The type of ground truth used.
    • Sample sizes for training sets.
    • How ground truth for training sets was established.

    Instead, the document primarily focuses on demonstrating substantial equivalence to a previously cleared device (K141791) based on intended use, indications for use, technological characteristics, and principles of operation, along with a risk analysis.

    AI/ML Overview

    Here's an analysis of the provided text regarding the acceptance criteria and study for the Biomet Fusion System, broken down by your requested categories:

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

    Acceptance Criteria CategorySpecific TestReported Device Performance
    Mechanical PropertiesStatic Compression (per ASTM F2077)Met acceptance criteria and functioned as intended.
    Static Compression Shear (per ASTM F2077)Met acceptance criteria and functioned as intended.
    Static Torsion (per ASTM F2077)Met acceptance criteria and functioned as intended.
    Dynamic Compression (per ASTM F2077)Met acceptance criteria and functioned as intended.
    Device Stability/FixationExpulsion Testing (per ASTM Draft Z8423Z)Met acceptance criteria and functioned as intended.
    Clinical Performance (implied)Cadaveric StudyMet acceptance criteria and functioned as intended.

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

    The document does not explicitly state the sample sizes for the mechanical tests. For the cadaveric study, the sample size is not specified. The provenance of the data (country of origin, retrospective/prospective) is also not mentioned.

    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 section is not applicable as the studies were primarily mechanical and cadaveric performance tests, not studies requiring expert interpretation of diagnostic images or clinical outcomes.

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

    Not applicable for mechanical and cadaveric performance tests. The "ground truth" for these tests is determined by the physical properties and behavior of the device under specific, standardized conditions.

    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 such study was conducted or mentioned in this document. This is a medical device (spinal implant) and the performance evaluation focuses on its mechanical properties and functionality, not diagnostic interpretation by human readers with or without AI assistance.

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

    This is not applicable as the device is a physical spinal implant, not an algorithm or AI system.

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

    For the mechanical tests, the "ground truth" is defined by the acceptance criteria of the relevant ASTM standards. For the cadaveric study, the "ground truth" would be the observed physical performance and stability of the device within the cadaveric specimens, measured against pre-defined performance metrics (though these specific metrics are not detailed in the summary).

    8. The sample size for the training set

    This is not applicable as the Biomet Fusion System is a physical medical device undergoing mechanical and cadaveric testing, not an AI or algorithm that requires a training set.

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

    Not applicable for the same reasons as point 8.
