Stabilis SA Cervical Stand-Alone System (Various PNs)
The Stabilis SA Cervical Stand-Alone System is indicated for intervertebral body fusion of the spine in skeletally mature patients who have had at least six months of non-operative treatment. The device system is designed for use with allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and/or autograft to facilitate fusion. One device is used per intervertebral body space.
The Stabilis SA Cervical Stand-Alone System is intended for use at either one level or two contiguous levels in the cervical spine, from C2 to T1, for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies.
Stabilis SA Cervical Stand-Alone System cages may be used as a stand-alone device when two (2) vertebral body bone screws are used. Stabilis SA Cervical Stand-Alone System cages with four (4) screw holes may be used as a stand-alone device when at least two (2) vertebral body bone screws are utilized with one inferior and one superior screw trajectory on opposite sides of the cage. If the physician chooses to use Stabilis SA Cervical Stand-Alone System cages with fewer than two (2) screws, then an additional supplemental spinal fixation system cleared for use in the cervical spine must be used.
Stabilis SA Cervical Stand-Alone System cages with four (4) screw holes may only be used at contiguous levels if at least two (2) vertebral body bone screws are utilized in each cage with one inferior and one superior screw trajectory on opposite sides of the cage, such that no more than two (2) vertebral body bone screws are implanted at the shared vertebral body with one inferior and one superior screw trajectory on opposite sides of the cages. Additionally, a cage with four (4) screw holes and a cage with two (2) screw holes can be implanted contiguously only if the cage with four (4) screw holes uses at least (2) vertebral body bone screws with one inferior screw on the left side of the cage and one superior screw on the right side of the cage.
The Stabilis SA cages are intervertebral body fusion devices intended for cervical interbody fusion using an anterior approach. The devices are intended to improve stability of the spine while supporting fusion. Stabilis SA constructs are intended for use at one or two contiguous levels in the cervical spine (C2-T1). The components are offered in different shapes and sizes to meet the requirements of the individual patient anatomy.
Stabilis SA Cervical Stand-Alone System cages are made of titanium alloy (Ti-6Al-4V ELI) per ASTM F3001 Standard Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) with Powder Bed Fusion. All cages are manufactured using the L-PBF (laser powder bed fusion) additive manufacturing method. L-PBF allows for the formation of solid, non-porous cages with a layered porous lattice structure on the surfaces of the components, including the surfaces of the interior graft window. This intricate structure facilitates bone in-growth by providing a larger surface of implant/bone contact than a buffed surface. The cages are also titanium anodized to allow for identification of various heights by color. The Stabilis SA Cervical Stand-Alone System cages are secured on the vertebral bodies using bone screws. The bone screws are machined from titanium alloy (Ti-6Al-4V ELI) per ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications and passivated according to ASTM F86 Standard Practice for Surface Preparation and Marking of Metallic Surgical Implants.
Stabilis Ti SA 2 Interbody, Stabilis Ti SA 2 Interbody, Curved, Stabilis Ti SA 4 Interbody, Stabilis Ti SA 4 Interbody, Curved, Stabilis Ti ZP Interbody, Stabilis Ti ZP Interbody, Curved cages, and bone screws are also available with a hydroxyapatite coating to increase implant anchoring by facilitating osseointegration and enhancing early bone growth. All Stabilis SA Cervical Stand-Alone implants are only available sterile packaged.
Non-sterile, reusable surgical instruments to support implantation of the system are provided for use with Stabilis SA Cervical Stand-Alone devices are provided in steam sterilization trays.

2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the exact sample size for the mechanical performance testing (e.g., number of devices tested for each mechanical test). It refers to the tests as being conducted on "the worst-case subject device" and "new implant sizes and configurations."
The data provenance is from non-clinical (mechanical and material) testing performed on the physical device, not patient data. Therefore, concepts like country of origin or retrospective/prospective do not apply in the typical sense for clinical studies.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This question is not applicable as this is a non-clinical device clearance for an intervertebral body fusion device, not an AI/software device requiring "ground truth" derived from expert interpretation of clinical data. The "ground truth" here is the adherence to established mechanical and material standards and the performance equivalence to predicate devices.
4. Adjudication Method for the Test Set
This question is not applicable. Adjudication methods like 2+1 or 3+1 refer to how expert disagreements are resolved when establishing ground truth in clinical data interpretation studies. This document describes mechanical and material testing, not clinical data assessment.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic or prognostic AI/software devices where human reader performance is being evaluated with and without AI assistance. This document pertains to the mechanical and material safety and effectiveness of a physical implant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not Applicable. This device is a physical implant, not an algorithm. Standalone performance typically refers to the diagnostic or predictive capability of an AI algorithm without human input or modification of the output.
7. The Type of Ground Truth Used
The "ground truth" in this context is established by:
- Adherence to recognized industry standards: ASTM F2077 (Test Methods for Intervertebral Body Fusion Devices), ASTM F2267 (Standard Test Method for Measuring Load Induced Subsidence of Intervertebral Body Fusion Devices Under Static Axial Compression), ASTM F3001 (Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI), ASTM F136 (Specification for Wrought Titanium-6Aluminum-4Vanadium ELI Alloy), and ASTM F86 (Practice for Surface Preparation and Marking of Metallic Surgical Implants).
- Performance equivalence to previously cleared predicate devices, as demonstrated through mechanical and material testing.
8. The Sample Size for the Training Set
Not Applicable. There is no "training set" as this is not an AI/machine learning device. The "training" for the device's design is based on engineering principles, material science, and the performance characteristics of previously cleared predicate devices.
9. How the Ground Truth for the Training Set Was Established
Not Applicable. As there is no training set in the context of AI/ML, there is no ground truth established for it. The standards and predicate devices guide the design and manufacturing, but this is a different concept than ground truth for machine learning.

Cervical Stand-Alone System
The Cervical Stand-Alone System is a stand-alone anterior cervical interbody fusion system indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one or two contiguous disc levels. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. The Cervical Stand-Alone System is used to facilitate intervertebral body fusion in the cervical spine and is placed via an anterior approach at one- or two-disc levels (C2-T1) using autograft bone. Patients should have at least six (6) weeks of non-operative treatment prior to treatment. The Cervical Stand-Alone Interbody Fusion System is intended to be used with the bone screw fixation provided and requires no additional fixation.
The Cervical Stand-Alone System implants are available in various heights and geometric footprints to accommodate individual patient anatomy and graft material size. Cervical Stand-Alone devices are inserted through an anterior cervical approach and packed with autogenous bone graft to facilitate fusion. Serrations on the superior and inferior surfaces of each device grip the endplates of the adjacent vertebral bodies to aid in expulsion resistance, while screws are inserted through the anterior face of the implant for bone fixation. The device is intended to provide mechanical support to the implanted level until biologic fusion is achieved. The cages are made from medical grade polyetheretherketone (PEEK) per ASTM F2026 with tantalum per ASTM F560 pins, from titanium alloy Ti-6A1-4V ELI per ASTM F136, or from additively manufactured Ti-6Al-4V per ASTM F3001. The integrated fixation screws and screw anti-backout plate are manufactured from Ti-6A1-4V ELI per ASTM F136. These devices are offered non-sterile.
The provided FDA 510(k) summary is for a medical device called the "Cervical Stand-Alone System," which is an anterior cervical interbody fusion system. This documentation primarily focuses on establishing substantial equivalence to predicate devices based on technological characteristics and mechanical performance data, rather than presenting a clinical study with detailed acceptance criteria for an AI/software device.
Therefore, many of the requested categories (e.g., sample size for test/training sets, experts for ground truth, MRMC studies, standalone performance for an algorithm) are not applicable to this type of device and submission. This is a physical implant, not an AI or software-based medical device.
However, I can extract the relevant "acceptance criteria" (which in this context refers to the performance standards the physical device must meet) and the "study" that proves it.

DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six weeks of non-operative treatment. The Genesys Spine Cervical Stand-Alone System is to be used with autogenous bone graft and implanted via an anterior approach.
The Genesys Spine AIS-C Cervical Stand-Alone System includes PEEK interbodies and titanium interbodies, which utilize an integrated titanium alloy locking mechanism. Both PEEK interbodies and titanium interbodies are to be anchored to patient anatomy via two (2) titanium alloy bone anchors. The integrated fixation anchors may not provide adequate stability for all situations. The Surgeon should consider the appropriate fixation required for each patient and determine if additional supplemental fixation (e.g. anterior plate, posterior cervical screws) may be needed. The PEEK interbody devices are made of polyether-ether-ketone (Invibio's PEEK Optima LT1) that conforms to ASTM F2026. Additionally, the PEEK implants contain tantalum markers per ASTM F560 to assist the surgeon with proper placement of the device in the disk space. The titanium alloy interbody devices, anchor locking mechanism, and the bone anchor components are manufactured from medical grade Ti6Al-4V ELI titanium alloy per ASTM F136.

Predetermined pass-fail criterion: mechanical test results for the Genesys Spine Cervical Stand-Alone System be equivalent to (or greater than) previously cleared interbody fusion systems. | The study concluded that the device achieved substantial equivalence to the predicate devices based on the mechanical test results and overall technological characteristics. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the exact sample sizes (number of devices or specimens) used for each mechanical test (axial compression, compressive-shear, torsion, subsidence, expulsion, cadaver testing, locking mechanism force). It only mentions that "all possible configurations of the AIS-C Cervical Stand-Alone System constructs were analyzed in order to determine the worst case to be used for testing."
The data provenance is not explicitly stated in terms of country of origin or whether it was retrospective or prospective. However, based on the nature of mechanical testing of devices, it is inherently prospective in the sense that new samples of the device are manufactured and specifically tested for the purpose of the study.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This information is not applicable as this study involves non-clinical mechanical testing of a medical device, not a study evaluating human performance or diagnostic accuracy where expert ground truth would be established. The "ground truth" here is adherence to mechanical standards (ASTM F2077-11, ASTM F2267-04) and comparison to predicate device performance.
4. Adjudication Method for the Test Set
This information is not applicable for the same reason as point 3. Mechanical testing results are objective measurements against defined standards and comparisons, not subjective interpretations requiring adjudication.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done
No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This study focuses on the mechanical performance of the device itself, not on the effectiveness of human readers (e.g., radiologists) with or without AI assistance.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable because the Genesys Spine AIS-C Cervical Stand-Alone System is a physical medical implant, not an algorithm or AI software. Therefore, there is no "standalone" algorithm performance to assess.
7. The Type of Ground Truth Used
The "ground truth" in this context is defined by:
- Established ASTM standards: Specifically, ASTM F2077-11 for static and dynamic axial compression, compressive-shear, and torsion; and ASTM F2267-04 for static subsidence.
- Performance of legally marketed predicate devices: The study's acceptance criterion was that the new device's mechanical test results should be "equivalent to (or greater than) previously cleared interbody fusion systems."
8. The Sample Size for the Training Set
This information is not applicable. This is a study of a physical medical device's mechanical properties, not an AI or machine learning model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable for the same reason as point 8.

This document is a 510(k) premarket notification for the CONSTRUX Mini PEEK Spacer System, CONSTRUX Mini PEEK Ti Spacer System, and Cervical Stand Alone System. It primarily addresses expanded indications for use, specifically the inclusion of allograft bone.
Based on the provided text, there is no acceptance criteria or a study proving the device meets specific performance criteria in the context of an AI/ML powered medical device. The document is for a medical implant (intervertebral body fusion device) and discusses its substantial equivalence to predicate devices, focusing on materials, design, and indications for use.
Therefore, most of the requested information regarding AI/ML device performance metrics, sample sizes, expert ground truth, MRMC studies, or standalone algorithm performance is not applicable to this document.
However, I can extract information related to the clinical data that supported the expanded indication:
1. A table of acceptance criteria and the reported device performance:
- Not Applicable. The document does not define specific performance acceptance criteria for an AI/ML device. It discusses the "substantial equivalence" of the implant system to predicate devices based on design, materials, and intended use, and the safety of using allograft bone.
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 explicitly stated. The document refers to "Published retrospective clinical data," not a specific test set with a defined sample size for this submission.
- Data Provenance: The data was "Published retrospective clinical data." The country of origin is not specified but implicitly relates to the use of similar cervical interbody fusion devices.
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. No ground truth establishment by experts for a specific test set is mentioned in the context of this 510(k) submission. The clinical data referred to supports the safety of using allograft bone.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not Applicable. No adjudication method is 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:
- Not Applicable. This document is for a physical medical implant, not an AI/ML device, so an MRMC study related to AI assistance is irrelevant here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This document is for a physical medical implant, not an AI/ML device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not Applicable in the context of an AI/ML ground truth. However, the "Published retrospective clinical data" would have relied on clinical outcomes data related to spinal fusion procedures and the use of allograft. The "outcomes demonstrated that the use of allograft... poses no new risks to patients."
8. The sample size for the training set:
- Not Applicable. No training set is mentioned as this is not an AI/ML device submission.
9. How the ground truth for the training set was established:
- Not Applicable. No training set or ground truth establishment for a training set is mentioned.
In summary, this 510(k) submission focuses on the substantial equivalence of a spinal implant system with expanded indications for use (specifically regarding bone graft material), rather than the performance of an AI/ML powered device.

Note: The provided document states that these tests were "conducted" in accordance with the specified ASTM standards. It does not provide specific numerical performance results or explicit pre-defined pass/fail criteria beyond the adherence to the standards. The basis of substantial equivalence is that the new device has "the same intended use, similar indications for use, the same technological characteristics and design, same materials and the same principles of operation as the predicate devices." Implied acceptance criteria are that the device's mechanical performance is equivalent to, or better than, the predicate devices when tested to these standards.
2. Sample Size for Test Set and Data Provenance
- Sample Size: Not explicitly stated in the provided text. The document mentions "mechanical testing" but does not detail the number of units or repetitions used for each test.
- Data Provenance: Not applicable in the context of clinical data. This study is described as "Non-Clinical Test Conducted." Therefore, there is no country of origin for clinical data, nor is it retrospective or prospective clinical data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Not applicable. This was a non-clinical, mechanical performance study. There was no "ground truth" derived from expert interpretation of images or patient outcomes. The "ground truth" for these tests would be the established scientific principles of mechanical engineering and the specifications of the ASTM standards themselves.
4. Adjudication Method for the Test Set
- Not applicable. As this was a non-clinical mechanical test, there was no need for expert adjudication. The results were likely compared against predefined limits or against the performance of predicate devices as per the ASTM standards.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No. The document describes non-clinical mechanical testing, not a clinical MRMC study involving human readers or AI assistance.
6. Standalone (Algorithm Only) Performance Study
- No. This device is a physical medical implant (intervertebral body fusion device), not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.
