SURGICAL TITANIUM MESH SYSTEM by DEPUY ACROMED

The Surgical Titanium Mesh System is indicated for use in the thoracolumbar spine (T1-L5) to replace a diseased vertebral body resected or excised for the treatment of tumors, to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body.

The Surgical Titanium Mesh System is also indicated for treating fractures of the thoracic and lumbar spine.

The Surgical Titanium Mesh System is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period.

The Surgical Titanium Mesh System is intended for use with supplemental internal fixation. The supplemental internal fixation systems that may be used with the Surgical Titanium Mesh System include DePuy AcroMed titanium plate or rod systems (e.g. Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss Miami, TiMX, Monarch and Profile).

AI/ML Overview

The provided text describes the regulatory clearance for the "Surgical Titanium Mesh™ System" as a medical device, focusing on its intended use and general performance data (biomechanical testing). It does NOT contain information about acceptance criteria for device performance, a study to prove it meets those criteria, sample sizes for test sets, data provenance, expert qualifications for ground truth, adjudication methods, MRMC studies, standalone algorithm performance, or how ground truth for training sets was established.

Therefore, most of the requested information cannot be extracted from the given text.

Here's what can be extracted based on the provided document:

1. A table of acceptance criteria and the reported device performance

Acceptance Criteria	Reported Device Performance
Not specified in the document	Biomechanical testing, including static axial compression and dynamic axial compression, were conducted. (Performance results and criteria for success are not detailed.)

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

Sample Size for Test Set: Not specified.
Data Provenance: Not specified. This document pertains to a 510(k) submission for a medical device and typically such submissions detail testing protocols and results, but this specific excerpt doesn't provide those details.

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 as this is a physical medical device (implant) and not related to AI or diagnostic image analysis where expert-established ground truth for a test set would be relevant.

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

Not applicable for a physical medical device.

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. This is a physical medical device, not an AI diagnostic tool.

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

Not applicable. This is a physical medical device, not an AI algorithm.

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

Not applicable. Performance for this device would be based on engineering and biomechanical standards, not a clinical "ground truth" as typically defined for diagnostic AI. The "performance data" mentioned is biomechanical testing.

8. The sample size for the training set

Not applicable. This is a physical medical device, not an AI algorithm.

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

Not applicable. This is a physical medical device, not an AI algorithm.

Trade Name: Titanium Mesh System - Addition of Components Regulation Number: 21 CFR 888.3060 Regulation Name: Vertebral Body Replacement Device Regulatory Class: II Product Code: MQP Dated: January 23, 2003 Received: January 24, 2003

Dear Mr. Maas:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.

Regulation Number and Section

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.
