The X-Spine ACP4 System is intended for anterior screw fixation to the cervical spine (C2-C7 inclusive). The system is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusion in patients with:

Degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies),
Spondylolisthesis,
Trauma (i.e., fractures or dislocations),
Tumors,
Deformity (defined as kyphosis, lordosis, or scoliosis) .
Pseudoarthrosis, and/or
Failed previous fusions.

Device Description

The X-Spine ACP4 System includes titanium alloy anterior cervical plates and bone screws. The plate attaches to the anterior portion of the vertebral body of the cervical spine, levels C2 to C7. The implant components are provided clean and non-sterile.

AI/ML Overview

The request is about the acceptance criteria and study proving the device meets the criteria. Specifically, it requests:

A table of acceptance criteria and reported device performance.
Sample size and data provenance for the test set.
Number and qualifications of experts for ground truth establishment (test set).
Adjudication method for the test set.
MRMC comparative effectiveness study details (if applicable).
Standalone performance study details (if applicable).
Type of ground truth used.
Sample size for the training set.
Ground truth establishment for the training set.

Based on the provided documents for K092360, the device is the "ACP4™ Spinal Implant System," which is a traditional medical device (cervical plating system) and not an AI/ML-based device. Therefore, the requested information, which pertains to AI/ML device performance criteria, ground truth, and expert evaluation, is not applicable to this submission.

The "PERFORMANCE DATA" section states: "Biomechanical testing indicates that the ACP4 system is capable of performing in accordance with its intended use." This indicates that the device's performance was evaluated through biomechanical tests, rather than clinical studies involving human readers, ground truth, or training sets as relevant for AI/ML systems.

Therefore, I cannot fulfill the request for information specifically tailored to AI/ML device evaluations based on the provided document. The document describes a traditional medical device submission, which does not typically include these types of performance evaluations.

Dear Dr. Kirschman:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
