E3D™ -A Static Interbody Devices are thoraco-lumbar interbody fusion devices indicated at one or more levels of the thoracic spine (T1-T12), thoracolumbar junction (T12- L1), or lumbosacral spine (L1-S1) as an adjunct to fusion in patients with the following indications: degenerative disc disease (DDD), disc herniation (with myelopathy and/or radiculopathy), spondylolisthesis, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and failed previous fusion (pseudarthrosis). DDD is defined as discogenic back pain with degeneration of the disc as confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. Devices are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. These devices are intended to be used with supplemental fixation systems that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems). Hyperlordotic interbody devices (≥20° lordosis) must be used with at least anterior supplemental fixation.

E3D™ -A Integrated Interbody Devices are integrated lumbar interbody fusion devices intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). Devices are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. These devices are intended to be used with three screws or anchors which accompany the implants. When used with screws, these devices are stand-alone interbody fusion devices. When used with anchors, these devices are intended for use with supplemental fixation (e.g., facet screws or posterior fixation). Hyperlordotic implants (≥20° lordosis) are intended for use with supplemental fixation (e.g., facet screws or posterior fixation). When used without screws or anchors, these devices are intended for use with supplemental fixation (e.g., facet screws or posterior fixation).

When used for multilevel degenerative scoliosis or sagittal deformity, supplemental fixation that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems) must be used.

The subject IdentiTi and Transcend Interbody Systems implants consist of various lengths, widths, heights and lordotic options to accommodate individual patient anatomy. To mitigate risk of expulsion, the interbody endplates feature teeth. All interbody spacers feature an internal graft aperture for placement of graft material to promote fusion through the cage. Additionally, the IdentiTi implants are offered with a microstructure due to the layering of material that forms the porous architecture. This porous geometry extends to the superior and inferior surfaces of the device for implant fixation. The IdentiTi and Transcend NanoTec Interbody Systems implant surfaces have been treated with a 20-40 nanometer thin hydroxyapatite (HA) surface treatment. The surface treatment presents nano-scale topography on the entirety of the implant surface, in addition to macro-/micro-scale topography existing from prior to treatment. The purpose of this Traditional 510(k) is to receive clearance for expanded indications for the treatment of degenerative spondylolisthesis, multilevel degenerative scoliosis, spinal stenosis, and sagittal deformity, and use of allogeneic bone consisting of cortical bone, as well as allogeneic bone consisting of demineralized allograft bone with bone marrow aspirate.

Here's an analysis of the provided text regarding acceptance criteria and supporting studies:

1. Table of Acceptance Criteria and Reported Device Performance

The provided document does not explicitly state specific acceptance criteria values (e.g., "device must withstand 1000N axial compression"). Instead, it lists the types of non-clinical tests performed, implying that the devices met the requirements of these standard tests. The reported "performance" is implicitly that the devices passed these tests.

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

The document does not specify the sample sizes used for each non-clinical test (e.g., number of interbody devices tested for axial compression). It refers to the tests generally.

Regarding data provenance, the tests are non-clinical (laboratory tests) and therefore do not involve patient data or data from specific countries of origin. The data is prospective as it was generated specifically for this submission.

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

This question is not applicable to this submission. The "ground truth" for the non-clinical performance tests is based on established engineering standards (ASTM) and the physical properties of the devices themselves, not on expert medical opinion or consensus.

4. Adjudication Method for the Test Set

This question is not applicable to this submission. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies or studies involving human readers/interpreters, where discrepancies in interpretation need to be resolved. The non-clinical tests outlined here are objective measurements against predefined standards.

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 question is not applicable to this submission. The device is an intervertebral body fusion system, a physical implant, not an AI diagnostic or assistance tool. Therefore, MRMC studies involving human readers or AI assistance are not relevant.

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

This question is not applicable to this submission. The device is a physical interbody fusion system, not an algorithm.

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

For the non-clinical performance tests, the "ground truth" is based on engineering standards and material science specifications. The tests are designed to assess the physical and mechanical properties of the interbody systems against recognized benchmarks for safety and effectiveness in their intended use.

8. The sample size for the training set

This question is not applicable to this submission. As the device is a physical implant and not an AI/ML algorithm, there is no "training set."

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

This question is not applicable to this submission for the same reason as above (no training set).
