These instruments are designed for use with the third party stereotactic navigation systems (Medtronic StealthStation™, Brainlab or 7D) software which are indicated for any medical condition in which the use of stereotactic surgery is suitable, and where reference to a rigid anatomical structure, such as vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized orientation points of the anatomy. ## Device Story Reusable surgical instruments (drill, tap, awl, driver, probe, depth stops) used in spinal surgery; assist surgeons in locating anatomical structures for screw placement. Instruments connect to third-party stereotactic navigation systems (Medtronic StealthStation, Brainlab, 7D) via universal adapters (clamp or screw design) that hold tracking arrays. Used in open or minimally invasive procedures. Surgeon operates instruments while navigation system provides real-time visualization relative to patient CT/MR models or fluoroscopy. Output allows precise site preparation and implant insertion; improves surgical accuracy and patient outcomes by guiding instrumentation relative to rigid vertebral structures. ## Clinical Evidence No clinical data. Bench testing only. Performance validated via ASTM F2554-22 testing including single point accuracy, axis/plane rotation, distance between points, target registration error, and tool reflectivity. ## Technological Characteristics Stainless steel surgical instruments (drill, tap, awl, driver, probe, depth stops). Universal adapters (clamp/screw design) for tracking array attachment. Compatible with third-party stereotactic navigation systems. Accuracy testing performed per ASTM F2554-22. ## Regulatory Identification A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system. ## Predicate Devices - Navigated INFINITY™ Instruments ([K173338](/device/K173338.md)) - VERTICALE® Navigation Instruments ([K223649](/device/K223649.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

The purpose of this submission is to add the VERTICALE® CERVICAL Navigation Instruments to the family of Silony Navigation Instruments and to add universal adapters which allow all Silony Navigation Instruments to be compatible with several navigation platforms. The subject VERTICALE® CERVICAL Navigation Instruments are used for site preparation and insertion of implants from the VERTICALE® CERVICAL System, previously cleared via K192013. The subject VERTICALE® CERVICAL Navigation Instruments include a drill, tap, awl, driver, probe, depth stops all manufactured from Stainless Steel. The VERTICALE® Navigation Adapters connect to the distal end of the navigation instruments and provide a connection for the tracking array of the navigation platform being used. The adapters are offered in two designs, a clamp design and a screw design. The VERTICALE® Navigation Adapters are compatible with VERTICALE® CERVICAL Navigation Instruments and VERTICALE® Thoracolumbar Navigation Instruments. ## Indications for Use The VERTICALE® Navigation Instruments are indicated for use during the preparation and insertion of VERTICALE® and VERTICALE® CERVICAL screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. These instruments are designed for use with the third party stereotactic navigation systems (Medtronic StealthStation™, Brainlab or 7D) software which are indicated for any medical condition in which the use of stereotactic surgery is suitable, and where reference to a rigid anatomical structure, such as vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized orientation points of the anatomy. K253921 - Page 1 of 3 {5} ## Technological Characteristics The predicates included in this submission were selected based on the best practices described in the FDA Draft Guidance document *Best Practices for Selecting a Predicate Device to Support a Premarket Notification [510(k)] Submission*. The subject and predicate devices have nearly identical technological characteristics and the minor differences do not raise any new issues of safety and effectiveness. Specifically, the following characteristics are identical between the subject and predicates: - Indications for Use - Materials of manufacture - Principles of Operation - Sterility - Navigation Platform - Types of Instruments - Implant Compatibility # Predicate Devices | 510k # | Trade or Proprietary or Model Name | Manufacturer | Product Code | Predicate Type | | --- | --- | --- | --- | --- | | K173338 | Navigated INFINITY™ Instruments | Medtronic Sofamor Danek USA, Inc. | OLO | Primary | | K223649 | VERTICALE® Navigation Instruments | Silony Medical GmbH | OLO | Additional | The technical characteristics of the subject VERTICALE® Navigation Instruments and universal adapters remain the same as, or similar to, the predicates in regard to indications for use, intended use, materials, and operational principles. To address any concerns for safety and efficacy due to differences in geometry of the subject instruments, accuracy testing was performed in accordance with ASTM F2554-22 *Standard Practice For Measurement of Positional Accuracy of Computer Assisted Surgical Systems*. The non-clinical verification and validation testing performed support the safety and efficacy of the VERTICALE® Navigation Instruments compatibility with the universal adapters and third-party navigation software. ## Performance Data The VERTICALE® Navigation Instruments has been tested in the following test modes: - Single point accuracy per ASTM F2554-22 - Instrument axis rotation per ASTM F2554-22 - Instrument perpendicular plane rotation per ASTM F2554-22 - Instrument parallel plane rotation per ASTM F2554-22 - Distance between points accuracy per ASTM F2554-22 - Target Registration Error Testing - Tool Reflectivity Testing The results of this non-clinical testing show that the strength of the VERTICALE® Navigation Instruments is sufficient for its intended use and is substantially equivalent to legally marketed predicate devices. K253921 - Page 2 of 3 {6} # Conclusion The overall technology characteristics and mechanical performance data lead to the conclusion that the VERTICALE® Navigation Instruments are substantially equivalent to the predicate device.
