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.
{4}------------------------------------------------
#### DEVICE DESCRIPTION: 2
This device is an image guided surgery system for navigated treatments in the fields of spine and trauma surgery, whereas the user may use 3D image data based on CT, MR or XT. The Software supports the surgeon in clinical procedures by displaying tracked instruments in patient image data.
### Operator profile
The operator's profile for this devices are Neuro / Ortho / Spine / Trauma surgeons or their assistants having a 3D image acquisition system (such as CT or 3D C-arm) in combination with a Brainlab navigation system.
#### Patient population
The patient population includes 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).
#### Intended use environment
The application shall be used in an operating room / suite.
#### Operating principle
Infrared passive marker based tracking as provided by the optical tracking camera unit of the navigation station is used to determine the instrument's and patient's position between the patient and the reference attached to the patient is realized with a registration (manually or automatic).

{5}------------------------------------------------
#### 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.
{6}------------------------------------------------
#### 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.
