The C-Tek® MaxAnTM Anterior Cervical Plate System is intended for anterior interbody fixation of the cervical spine. Indications for use include the temporary stabilization of the anterior spine during the development of cervical fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin confirmed by patient history and radiographic studies), trauma including fractures, tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudarthroses, and/or failed previous fusions. The intended levels for treatment range from C2 - T1.

The C-Tek® MaxAn™ Anterior Cervical Plate System consists of titanium alloy plates and screws. Screws are provided in both fixed and variable versions in sizes 4.0 mm and 4.5 mm with lengths from 8-26 mm. Screws will be provided in both sterile and nonsterile configurations. Cervical plates are provided in both sterile and non-sterile configurations for 1 - 6 levels and in appropriate lengths from 8-150 mm.

The provided text describes a 510(k) premarket notification for a medical device called the C-Tek® MaxAn™ Anterior Cervical Plate System. This is a spinal intervertebral body fixation orthosis.

Based on the document, this is not an AI/ML medical device. It is a traditional medical device (a physical implantable system of plates and screws). Therefore, many of the requested fields related to AI/ML device studies (such as sample size for training/test sets, expert adjudication, MRMC studies, standalone performance, etc.) are not applicable and cannot be extracted from this type of submission.

Here's a breakdown of the information that is available and a note on what is not applicable:

Acceptance Criteria and Reported Device Performance

Study Details:

1. Sample size used for the test set and the data provenance: Not applicable for this type of medical device (physical implant). The "test set" would refer to the physical prototypes tested in non-clinical lab settings. The document does not specify the number of samples or prototypes tested. Data provenance is not relevant in the context of clinical data for an AI/ML device.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth, in the context of an AI/ML device, refers to verified labels for data. For a physical medical device, "ground truth" would relate to engineering specifications and performance standards.
3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. This refers to methods for consensus building among human experts labeling data, which is not relevant for this device.
4. 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 is not an AI/ML device and human readers are not involved in its "performance" in this context.
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI/ML device.
6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): For this physical device, the "ground truth" for performance is likely based on engineering specifications, material properties (ASTM F-136 for Ti-6Al-4V), and biomechanical testing standards for spinal implants, demonstrating equivalency to predicate devices. The document explicitly states "Non-clinical laboratory testing was performed to determine substantial equivalence."
7. The sample size for the training set: Not applicable. This is not an AI/ML device.
8. How the ground truth for the training set was established: Not applicable. This is not an AI/ML device.

Ask a specific question about this device

The indications for use for the modified devices described in this submission are the same as those for the previously cleared SWIFT Anterior Cervical Plate System. The indications are as follows:

The SWIFT™ Plus Anterior Cervical Plate System is intended for anterior cervical intervertebral body fixation. This system is indicated for patients in which stability is desired following anterior cervical fusion for the indications listed below. The intended levels for treatment range from C2 to T1.

Indications include symptomatic cervical spondylosis, trauma, fracture, post-traumatic kyphosis or lordosis, tumor, degenerative disc disease (defined as pain with degeneration of the disc discogenic confirmed by history and radiographic studies), reoperation for failed fusion, or instability following surgery for the above indications.

The SWIFT Plus Anterior Cervical Plate System consists of an assortment of plates and screws.

The SWIFT Plus Anterior Cervical Plate System also contains Class 1 manual surgical instruments and cases that are considered exempt from premarket notification.

It looks like the text provided is a 510(k) summary for a medical device called the SWIFT™ Plus Anterior Cervical Plate System. This document outlines the device description, intended use, and materials.

However, the provided text does not contain any information regarding acceptance criteria, device performance metrics (numerical or otherwise), sample sizes for testing or training, data provenance, expert information, adjudication methods, or different types of studies (MRMC, standalone).

The "PERFORMANCE DATA:" section is present, but it only states "Performance data were submitted to characterize the SWIFT Plus Anterior Cervical Plate System." without providing any specifics. Medical device submissions like 510(k)s typically include detailed performance data, but this specific excerpt is lacking that information.

Therefore, I cannot fulfill your request for the tables and detailed information about acceptance criteria and study designs based solely on the text provided. To answer your questions, I would need a section that explicitly details the performance testing results, acceptance criteria, test methodologies, and clinical study information.
