NEO Pedicle Screw System™
The NEO Pedicle Screw System™, when used as a posterior pedicle screw system, is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion. The system is intended for posterior, non-cervical 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 (scoliosis, kyphosis), tumor, pseudarthrosis, and/or failed previous fusion.
When used in conjunction with BonOs® Inject Cement, the NEO Pedicle Screw System™ is intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion. NEO Pedicle Screws augmented with BonOs® Inject Cement are for use with 5 mm to 8 mm screw diameters at spinal levels (thoracic and lumbar T1 to L5) where the structural integrity of the spine is not severely compromised.
BonOs® Inject
BonOs® Inject bone cement is indicated for the treatment of pathological fractures of the vertebral body due to osteoporosis, cancer, or benign lesions using vertebroplasty or balloon kyphoplasty procedure.

- BonOs® Iniect
BonOs® Iniect is a radiopaque, iniectable bone cement for use in spine surgery like percutaneous vertebral augmentation during vertebroplasty or kyphoplasty. It is a twocomponent system consisting of a powder and a liguid. Methylmethacrylate polymer is the primary constituent of the powder component. Zirconium dioxide is added as radiopacifier. Methylmethacrylate monomer is the primary constituent of the liquid component. Mixing the two separate sterile components, initially an injectable paste is produced which can be transferred into a syringe and which then can be injected under slight pressure into the vertebral body. After curing of the bone cement by exothermic polymerization it stabilizes the vertebral lesions and vertebral compression fractures.

The provided text is an FDA 510(k) clearance letter and a 510(k) summary for a medical device called the "NEO Pedicle Screw System™" and "BonOs® Inject Bone Cement." This document details the administrative information, device description, indications for use, and a summary of performance data to support substantial equivalence to a predicate device.
However, the document specifies that "No clinical studies were conducted." This means that the information requested regarding acceptance criteria for a study proving device performance (especially for AI/algorithm-based devices), sample size for test and training sets, expert involvement, adjudication methods, MRMC studies, standalone algorithm performance, and ground truth establishment cannot be provided from this document.
The performance data mentioned in the document are limited to non-clinical testing, primarily focusing on mechanical performance, biological evaluation, and MRI compatibility. These types of tests are used to demonstrate that changes to the device (like new components or size extensions) do not negatively impact its existing, cleared performance characteristics, and that it is substantially equivalent to the predicate device.
Therefore, I cannot populate the requested table or answer the specific questions related to the acceptance criteria and study that proves the device meets the acceptance criteria in the context of an AI/algorithm-driven device's performance study, as this submission is for a physical orthopedic implant system, not a software or AI product requiring such a study.
Here's what can be inferred from the document regarding "acceptance criteria" and "proof" in the context of this device:
The "acceptance criteria" for the modifications introduced in this 510(k) submission are implicitly met if the device demonstrates substantial equivalence to its predicate device. This is primarily demonstrated through:
- Mechanical Performance: Meeting the requirements for pedicle screw spinal systems according to relevant ASTM and ISO standards (e.g., ASTM F1717 for dynamic compression bending). The document states: "Non-clinical performance testing demonstrate that the NEO Pedicle Screw System™ meets the requirements for Pedicle screw spinal systems according to Spinal System 510(k)s Guidance for Industry and FDA Staff Document issued on: May 3, 2004 and is substantially equivalent to its predicate devices."
- Biological Evaluation: Compliance with ISO 10993-1 series for the new components.
- MRI Compatibility: Meeting standards like ASTM F2052-15, ASTM F2182-11a, and ASTM F2119-07 (R2013).

The provided text is a 510(k) summary for the BonOs® Inject Bone Cement and NEO Pedicle Screw System™. It outlines the administrative information, device description, indications for use, and a comparison to a predicate device. However, it explicitly states, "No clinical studies were conducted," and the provided "SUMMARY OF PERFORMANCE DATA" primarily focuses on non-clinical, mechanical testing (static and dynamic testing, and axial gripping capacity in accordance with ASTM 1798), usability, biocompatibility, MRI safety, and sterilization validation.
Therefore, the document does not contain information about acceptance criteria or a study that proves the device meets specific acceptance criteria based on clinical outcomes or performance metrics typically seen in AI/ML device studies. It is likely that the "acceptance criteria" here refer to meeting the predicate device's performance through bench testing, rather than performance against a clinical ground truth.
Given this, I cannot fully complete the requested table and answer many of the questions as the information is not present in the provided text. I will indicate where information is missing.
1. A table of acceptance criteria and the reported device performance
Since this is a mechanical device and not an AI/ML diagnostic, the "acceptance criteria" and "reported performance" are typically related to engineering and material standards, not diagnostic metrics like sensitivity or specificity. The document mentions meeting requirements for pedicle screw spinal systems.
| Acceptance Criteria (Implied from text) | Reported Device Performance |
|---|---|
| Requirements for Pedicle Screw Spinal Systems (Spinal System 510(k)s Guidance for Industry and FDA Staff Document, May 3, 2004) | The NEO Pedicle Screw System™ meets these requirements. |
| Static and dynamic testing in accordance with ASTM 1798 | Performed; results demonstrate substantial equivalence to predicate. |
| Axial gripping capacity in accordance with ASTM 1798 | Performed; results demonstrate substantial equivalence to predicate. |
| Usability, Biocompatibility, MRI safety and compatibility, Sterilization process validation (in context of K212489) | Evaluated; results demonstrate substantial equivalence to predicate. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not applicable. The performance data described is based on non-clinical (bench) testing, not a clinical test set.
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 clinical ground truth was established as "No clinical studies were conducted."
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. No clinical test set or adjudication was performed.
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. This document does not mention any MRMC study. The device is a physical pedicle screw system and bone cement, not an AI diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The device is a physical pedicle screw system and bone cement, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
