The summary describes a standard image-guided navigation system. There are no mentions of AI, ML, deep learning, or any related concepts in the intended use, device description, or performance studies. The performance studies focus on software verification and regression testing, not on evaluating the performance of an AI/ML algorithm.
No.
This device is an image-guided navigation system that assists surgeons in placing instruments during surgery; it does not directly treat or provide therapy to a medical condition.
No
Explanation: The device is described as an "intraoperative image-guided localization system" and an "image guided surgery system for navigated treatments." Its purpose is to assist surgeons in visualizing and tracking instruments during surgery, not to diagnose medical conditions or diseases.
No
The device description explicitly states it is an "image guided surgery system" and mentions tracking instruments, implying the use of hardware components beyond just software. The intended use also refers to linking a "freehand probe, tracked by a passive marker sensor system," which are hardware elements.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The Spine & Trauma Navigation System is an image-guided surgery system. Its purpose is to assist surgeons during procedures by providing real-time localization and navigation based on medical images. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "intraoperative image-guided localization system" and "computer-assisted navigation of medical image data." This is a surgical tool, not a diagnostic test performed on a sample.
- Device Description: The description reinforces its role as an "image guided surgery system" that displays tracked instruments in patient image data.
- Lack of Specimen Analysis: There is no mention of collecting or analyzing any biological specimens from the patient.
Therefore, the Spine & Trauma Navigation System falls under the category of a surgical navigation system, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
Spine & Trauma Navigation System is intended as an intraoperative image-guided localization system to enable minimally invasive surgery. It links a freehand probe, tracked by a passive marker sensor system to virtual computer image space on a patient's preoperative or Intraoperative 2D or 3D image data.
Spine & Trauma Navigation System enables computer-assisted navigation of medical image data, which can either be acquired preoperatively or intraoperatively by an appropriate image acquisition system.
The software offers screw implant size planning and navigation on rigid bone structures with precalibrated and additional individually-calibrated surgical tools.
The system is indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where a reference to a rigid anatomical structure, such as the skull, the pelvis, a long bone or vertebra can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Testing:
- Interactive tests according to verification documents related to changed software parts (software . code change verification)
- . Interactive tests according to verification documents related to unchanged software parts (regression tests)
- Code review of the software change
- Software memory leakage tests using VLD (Visual Leak Detector)
- . Static code analysis (Lint) for changed software parts
Worst case scenarios were considered. New verification activities were performed after extension of existing test cases. They cover switching between different applications within one navigation session and now additionally comprise the missing test scenario for the display issue which caused the software modification request. In order to prevent software changes to have impact on non-changed design parts, regression tests were included to the test protocols.
Design verification testing that was performed to support modifications to the Spine & Trauma Navigation System software met all design and performance requirements.

Use scenarios
The system is placed in a way that the surgeon can easily watch the screen(s) and interact with the system during the procedure, but sterility is not compromised. The camera is positioned in a way that it has an unobstructed view on the surgical field.
The patient is positioned and draped in the usual manner, taking into account that the reference geomety has to be attached to the relevant anatomical structure in a way that it is not disturbing the latter workflow. The surgical approach is performed. A reference arrav is attached to the relevant bony structure using conventional surgical techniques (either under sight or minimally invasive). The 3D dataset is either acquired or loaded and subsequently registered.
After the scan has been transmitted to the navigation system or the registration computation has been performed, the surgeon is asked to verify the success of the registration with a general instrument or a dedicated pointer.
After successful verification the surgeon is able to access pre-planned objects, to plan or re-plan screws / trajectories and to visualize manually or pre-calibrated surgical instruments.
Intended part of the body or type of tissue applied to or interacted with
This system has different components, whereas most of them are software. Therefore, only instruments may get in contact with a patient, some instruments are included to perform the surgery. All Instruments are used temporarily for orientation within the situs or for preparations to be able to implant 3rd party devices, which are not part of this system.
Such instruments can be used at rigid bony structures, such as a long bone or vertebra, where the user wants to use this navigation software according to the indications for use.
SUBSTANTIAL EQUIVALENCE ന
The Spine & Trauma Navigation System has similar functionality, intended use, technological characteristics, and typical users as the predicate device.
The proposed software modification was performed to correct a display issue within the Spine & Trauma Navigation System software that can occur when a user changes navigation workflows. The issue was caused by an erroneous orientation of the anatomical slices that were displayed together with a projected instrument representation within axial and coronal/sagittal views of the image data, while the instrument tip was permanently correctly displayed.
The proposed software modification required a local software consisting of 14 lines of code and is restricted to two source files.
Since the programming structure for the current display logic was already intended in the detailed design, the software correction did not require any change to the existing software architecture or to the unit tests.
There was no change of intended use, technological characteristics or typical users.

VERIFICATION/VALIDATION SUMMARY ব
Performance Testing
The following verification methods were successfully applied:
- Interactive tests according to verification documents related to changed software parts (software . code change verification)
- . Interactive tests according to verification documents related to unchanged software parts (regression tests)
- Code review of the software change
- Software memory leakage tests using VLD (Visual Leak Detector)
- . Static code analysis (Lint) for changed software parts
Worst case scenarios were considered. New verification activities were performed after extension of existing test cases. They cover switching between different applications within one navigation session and now additionally comprise the missing test scenario for the display issue which caused the software modification request. In order to prevent software changes to have impact on non-changed design parts, regression tests were included to the test protocols.
Design verification testing that was performed to support modifications to the Spine & Trauma Navigation System software met all design and performance requirements.
CONCLUSION 5
The modified device is substantially equivalent to the currently marketed Spine & Trauma Navigation System based upon design verification test results and the indications for use.
