Exporting

NavNX provides several export options to share surgical plans with colleagues, integrate with other systems, or produce printed documentation.

​
Export STL

Export the 3D bone model as an STL file for use in external 3D viewers, 3D printing, or integration with other surgical planning tools.
1

Open the Bone 3D view

Navigate to the Bone view and adjust the threshold to capture the desired anatomy.
2

Click Export STL

Click the Export STL button in the toolbar.
3

Download

The STL file is generated and downloaded to your browser’s default download folder.
The exported STL reflects the current threshold setting. Adjust the threshold before exporting to control which structures are included in the mesh.

​
Export Case Data (JSON)

Export the complete case plan as a structured JSON file. This includes:
  • Patient demographics (name, MRN, DOB)
  • Procedure type and side
  • Tunnel parameters (coordinates, angles, diameter, depth)
  • Selected implant and size
  • Graft configuration
  • Measurements
  • Case notes
To export: open the case detail page, click Export, and select Case Data (JSON).

​
Export FHIR R4 Bundle

Export the surgical plan as a FHIR R4 Bundle for integration with hospital information systems, EHRs, and PACS. To export: open the case detail page and click the FHIR R4 button. A JSON file is downloaded containing a FHIR collection Bundle.

​
Resources Included

​
SNOMED CT Procedure Codes

The FHIR export uses base FHIR R4 profiles. No US Core or IHE profiles are required. The bundle can be validated against the standard FHIR R4 specification.
Generate a formatted pre-operative report for printing or saving as PDF:
  1. Open the case detail page or click Pre-Op Report in the planner toolbar.
  2. The report opens in a new browser tab.
  3. Use your browser’s print function (Ctrl+P) to print or save as PDF.
The report includes:
  • Patient & case information — demographics, procedure type, side, planned date
  • Tunnel placement parameters — entry/exit coordinates, angles, diameter, depth
  • Tunnel density profiles — HU line chart along each tunnel path with colour-coded zones (cortical, cancellous, soft tissue) and min/max HU values
  • Implant selection — manufacturer, product name, tunnel assignment
  • 2D annotations summary — table of all measurements, arrows, circles, and rectangles with computed values (mm, degrees, area) and slice location
  • 3D visualisation settings — threshold, opacity, render mode, crop status
  • Case notes — timestamped clinical notes
See Pre-Op Report for details on report content.
Exported files may contain protected health information (PHI). Handle exported data in accordance with your organisation’s data security policies.
The JSON export is useful for archiving case plans or transferring plan data to other systems. The format is stable and documented.
