The uCerv Flux ™-C 3D Porous Titanium Cervical Interbody is indicated for intervertebral body fusion in skeletally mature patients with cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiographs, CT, MRI), that results in radiculopathy, myelopathy, and/or pain at multiple contiguous levels from C2-T1. The device system is designed for use with supplemental fixation cleared for use in the cervical spine and with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone and/or demineralized allograft bone with bone marrow aspirate to facilitate fusion. The hyperlordotic implants (≥ 10°) are required to be used with an anterior cervical plate. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral cage.
The uCerv Flux™-C 3D Porous Titanium Cervical Interbody implants are additively manufactured interbody fusion devices for cervical implantation. The implants are designed having porous surfaces to provide surgical stabilization of the spine. Each interbody has a central cavity that can be packed with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft material and lateral windows for radiographic visualization. The implants are available in a variety of height, length, width and lordotic angulation combinations to accommodate the patient specific anatomy and clinical circumstances.
The provided FDA document is a 510(k) clearance letter for a medical device, not a study evaluating an AI algorithm's performance. Therefore, most of the requested information regarding acceptance criteria, study design, expert involvement, and ground truth for AI algorithms is not present in this document.
The document describes the uCerv Flux™-C 3D Porous Titanium Cervical Interbody, an intervertebral body fusion device. The acceptance criteria and "study" described relate to the mechanical performance of this physical device, not a digital diagnostic or AI-driven system.
Here's the relevant information based on the provided text:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Type of Testing) | Reported Device Performance |
|---|---|
| Static Axial Compression (ASTM F2077) | Meets performance requirements (implied by substantial equivalence to predicate devices, and that an engineering rationale was used to demonstrate that additional sizes did not introduce a new worst case). |
| Dynamic Axial Compression (ASTM F2077) | Meets performance requirements (implied by substantial equivalence to predicate devices, and that an engineering rationale was used to demonstrate that additional sizes did not introduce a new worst case). |
| Static Torsion (ASTM F2077) | Meets performance requirements (implied by substantial equivalence to predicate devices, and that an engineering rationale was used to demonstrate that additional sizes did not introduce a new worst case). |
| Subsidence (ASTM F2267) | Meets performance requirements (implied by substantial equivalence to predicate devices, and that an engineering rationale was used to demonstrate that additional sizes did not introduce a new worst case). |
| Dynamic Torsion (ASTM F2077) | The mechanical test results demonstrate that the uCerv Flux™-C 3D Porous Titanium Cervical Interbody performance is substantially equivalent to the predicate devices. |
| Expulsion Tests | The mechanical test results demonstrate that the uCerv Flux™-C 3D Porous Titanium Cervical Interbody performance is substantially equivalent to the predicate devices. |
Explanation: The document states that "Mechanical testing of the worst case Flux-C devices was relied upon in support of the original uCerv Flux™-C 3D Porous Titanium Cervical Interbody clearance. The testing included static and dynamic axial compression and static torsion according to ASTM F2077 and subsidence according to ASTM F2267. An engineering rationale was used to demonstrate that the additional cervical interbody sizes did not introduce a new worst case." It further mentions, "Mechanical testing of the worst case subject uCerv Flux™-C 3D Porous Titanium Cervical Interbody implants included dynamic torsion according to ASTM F2077 and expulsion tests. The mechanical test results demonstrate that the uCerv Flux™-C 3D Porous Titanium Cervical Interbody performance is substantially equivalent to the predicate devices." The acceptance criteria are implicit in meeting the standards (ASTM F2077, ASTM F2267) and demonstrating substantial equivalence to predicate devices. Specific numerical thresholds for acceptance are not provided in this summary.
Regarding the remaining points (2-9), the provided document does not contain information about an AI algorithm or a study involving human readers, so these points cannot be addressed. The document is for a physical orthopedic implant.
Here's why the other points are not applicable:
- 2. Sample size used for the test set and the data provenance: Not applicable. This document is about a physical device's mechanical performance, not an AI test set with data.
- 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No ground truth for an AI test set is mentioned.
- 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No test set for an AI algorithm 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. No AI assistance or human reader study is discussed.
- 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. No algorithm is involved.
- 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable. The "ground truth" for the device is its mechanical integrity and performance as per ASTM standards, compared to predicate devices.
- 8. The sample size for the training set: Not applicable. No AI training set is mentioned.
- 9. How the ground truth for the training set was established: Not applicable. No AI training set is mentioned.

§ 888.3080 Intervertebral body fusion device.
(a)
Identification. An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.(b)
Classification. (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
