## Intended Use

The Rhausler RT2 Trabeculite Titanium Cervical Cage System is intended for spinal fusion procedures at one level (C3-T1) in skeletally mature patients with cervical disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). Implants are to be implanted via an open, anterior approach and packed with autogenous bone. This device is to be used in patients who have at least 6 weeks of nonoperative treatment. This device is intended to be used with supplemental spinal fixation systems.

## Device Story

Cervical intervertebral body fusion device; rectangular, lordotic titanium alloy (Ti6Al4V) cage; hollow center for autogenous bone graft. Used in open, anterior cervical spine surgery; requires supplemental spinal fixation. Implanted by orthopedic or neurosurgeons to facilitate fusion in patients with discogenic neck pain. Provides structural support to vertebral space during bone healing; benefits patient by stabilizing segment and promoting fusion.

## Clinical Evidence

Bench testing only. Mechanical testing per ASTM F2077-11 (static/dynamic compression and torsion) and ASTM F2267-04 (subsidence and expulsion). Biocompatibility testing per ISO 10993 and GLP regulations. Sterilization validation per ANSI/AAMI/ISO 11137-1/2.

## Technological Characteristics

Material: Medical grade Titanium alloy (Ti6Al4V). Form: Rectangular cage with 4-degree lordotic profile, hollow cylindrical fenestration. Dimensions: Two cross-sectional sizes, various heights. Sterilization: ANSI/AAMI/ISO 11137-1/2 (SAL 10^-6). Mechanical standards: ASTM F2077-11, ASTM F2267-04.

## Regulatory Identification

An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.

## Special Controls

*Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
*Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

| Device Description:     | The Rhausler RT2 Trabeculite Titanium Cervical Cage System is a<br>cervical intervertebral body fusion device. The system is comprised<br>of implants and instruments. The instruments are utilized for the<br>implantation procedure. All implants are manufactured from<br>medical grade Titanium alloy (Ti6 Al 4V).<br>The implant is rectangular in shape with lordotic configuration, i.e.,<br>with 4 degree profiles. It is offered in two cross sectional sizes and<br>is available in various height options to accommodate variations in<br>patient anatomy. The center of the implant has a hollow cylindrical<br>shape fenestration for placement of autogenous bone. Trabeculite<br>Titanium Cervical Cage implant is provided sterile. |
| Indications For Use:    | The Rhausler RT2 Trabeculite Titanium Cervical Cage System is<br>intended for spinal fusion procedures at one level (C3-T1) in<br>skeletally mature patients with cervical disc disease (defined as<br>neck pain of discogenic origin with degeneration of the disc<br>confirmed by history and radiographic studies). Implants are to be                                                                                                                                                                                                                                                                                                                                                                                                           |

| Technological<br>Comparison to Predicate<br>Device: | The Rhausler RT2 Trabeculite Titanium Cervical Cage System             is equivalent to the predicate devices. Both are intervertebral             body fusion devices that attach to the anterior portion of the             cervical spine during the development of spinal fusion.             Additionally, both use the same fundamental scientific             technology, principle of operation, and materials. Performance             test results confirm that design differences do not pose new issues             of safety or effectiveness.                                                                                                                                        |
| Performance Testing:                                | Mechanical testing has been performed on the RT2 Trabeculite             Titanium Cervical Cage System in accordance to the FDA             recommendation entitled "Class II Special Controls Guidance             Document: Intervertebral Body Fusion Device", which included             Compression tests (Static and Dynamic) and Torsion tests (Static             and Dynamic) per ASTM F2077-11, Subsidence testing per ASTM             F2267-04 and Expulsion test. The results of testing and analyses             conducted, demonstrate that the proposed system adequately meets             the predetermined requirements established for its mechanical             performance. |
|                                                     | Biocompatibility tests for the RT2 Trabeculite Titanium Cervical             Cage were selected in accordance with blue book memorandum             G95-1 entitled Use of International Standard ISO 10993,             "Biological Evaluation of Medical Devices - Part 1: Evaluation             and Testing". Biocompatibility tests were conducted in compliance             with U.S. Food and Drug Administration Good Laboratory             Practice (GLP) regulations set forth in 21 CFR 58. All tests             conducted passed biocompatibility requirements.                                                                                                                       |
|                                                     | Sterilization validation of the RT2 Trabeculite Titanium Cervical             Cage implant is to be based on the requirements of             ANSI/AAMI/ISO 11137-1:2006 (R) 2010 and 11137-2:2013 with             a minimum Sterility Assurance Level of 1X10-6                                                                                                                                                                                                                                                                                                                                                                                                                                   |
| Conclusion:                                         | Based upon the design, technology, performance, and intended use,             the Rhausler RT2 Trabeculite Titanium Cervical Cage             System is substantially equivalent to the predicate device/s currently             marketed under the Food, Drug and Cosmetic Act.                                                                                                                                                                                                                                                                                                                                                                                                                   |
