The Retain Radiolucent Spacer is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). The Retain Radiolucent Spacer is intended to be used with supplemental spinal fixation systems that have been labeled for use in the thoracic and/or lumbar spine (i.e., posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems). The interior of the spacer can be packed with bone grafting material.

The Retain Radiolucent Spacer is designed to provide anterior spinal column support even in the absence of fusion for a prolonged period.

Device Description

The Retain Radiolucent Spacer is a vertebral body replacement device used to provide structural stability in skeletally mature individuals following corpectomy or vertebrectomy. The system is comprised of spacers of various fixed heights and footprints to fit the anatomical needs of a wide variety of patients. Each spacer has large open area to allow grafting material to be packed inside of the spacer. Ridges on the superior and inferior surfaces of each device help to grip the endplates of the adjacent vertebrae to resist expulsion.

The Retain Radiolucent Spacer devices are made from radiolucent polymer, titanium alloy and tantalum as specified in ASTM F2026, F136, F1295, and F560.

AI/ML Overview

This request cannot be fulfilled. The provided text is a 510(k) summary for a medical device (Retain Radiolucent Spacer) and does not contain information typically found in a study describing acceptance criteria and device performance as requested.

Specifically, the document focuses on:

Device Description: What the Retain Radiolucent Spacer is made of and its components.
Intended Use: The medical conditions and anatomical locations for which the device is designed.
Predicate Device: Its similarity to a previously cleared device (Sustain Radiolucent Spacer K040284).
Regulatory Information: Classification, product code, and the FDA's clearance letter.
Performance Data: It merely states "Mechanical testing in accordance with the 'Guidance for Industry and FDA Staff, Guidance for Spinal System 510(k)s', May 3, 2004 was presented." This does not provide specific acceptance criteria, reported performance values, or details about a study for proving these criteria.

Therefore, the requested information cannot be extracted from the provided text. A study report with detailed performance metrics, acceptance criteria tables, sample sizes, ground truth establishment, etc., would be needed to answer the prompt.

Dear Dr. Baker:

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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

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.
