The indications for the use of the Howmedica Osteonics® ACCP System are as follows:

• degenerative disc disease (neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies).
• decompression of the spinal cord following total or partial cervical vertebrectomy .
• . trauma (fractures)
• . tumors
• pseudarthrosis .
• . failed previous fusions

The Howmedica Osteonics® ACCP System is an anterior cervical single or multi-level plate that incorporates either a monoblock or modular design, which is measured from end to end. Modular end plate sections are secured to each other using locking screws, and are provided preassembled. The Howmedica Osteonics® ACCP is placed longitudinally on the long axis of the cervical spine and is affixed by cortical bone screws. All Howmedica Osteonics® ACCP System components are manufactured from ASTM F-136-98 (ISO 5832/3) titanium alloy.

The provided document is a 510(k) Premarket Notification Summary for the Howmedica Osteonics® ACCP System - Cortical Screws. This document focuses on the substantial equivalence of a new device to a predicate device, rather than providing details on a study performed to meet specific acceptance criteria for a novel device.

Therefore, most of the requested information regarding acceptance criteria and a study proving the device meets those criteria cannot be extracted from this document, as it describes a regulatory submission for a device component based on equivalence, not a new device requiring extensive performance testing against defined metrics.

Here's a breakdown of what can be inferred or stated from the provided text based on your request:

1. Table of acceptance criteria and the reported device performance:

This information is not present in the document. The submission is a 510(k) for a component (cortical screws) of an existing system (ACCP System). The primary "acceptance criteria" here is substantial equivalence to a predicate device, not performance metrics from a new study.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

This information is not present. The document does not describe a performance study with a test set.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not present. There is no "test set" described as part of a performance study.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

This information is not present. There is no "test set" described as part of a performance study.

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:

This information is not present. The device is a physical medical implant (cortical screws), not an AI-assisted diagnostic or therapeutic tool. Therefore, an MRMC study related to AI assistance would not be applicable.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

This information is not present. The device is a physical medical implant, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

This information is not present. There is no "ground truth" mentioned as part of a performance study. The ground for the submission is the substantial equivalence to an existing, legally marketed predicate device.

8. The sample size for the training set:

This information is not present. The document does not describe a machine learning algorithm or a training set.

9. How the ground truth for the training set was established:

This information is not present. The document does not describe a machine learning algorithm or a training set.
