Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Tracking / registration fault
HighSymptoms: Instrument or reference-frame position drifts, registration fails, navigation inaccurate.
Root cause: Camera (optical) or field generator (EM) fault, a line-of-sight / interference issue, or reference-frame / tracker-marker damage.
Tracked instrument / probe fault
MediumSymptoms: Instrument not detected, erratic tip position, calibration fails.
Root cause: Damaged tracker array, reflective spheres, or a wired tracker cable.
Camera / positioning-arm fault
MediumSymptoms: Camera will not move to command, drifts, or loses tracking volume.
Root cause: Camera arm drive or the camera head.
Workstation / imaging-import fault
MediumSymptoms: CT / MR dataset will not load, planning software hangs, no navigation view to the displays.
Root cause: Workstation PC, media / network import, or a video-output fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Tracking inaccurate / registration fails
- Confirm clear line of sight (optical) or remove ferrous interference (EM).
- Fit fresh reflective spheres and check the tracker arrays for damage.
- Re-run registration per the workflow.
- Verify accuracy against a known landmark.
- Escalate a confirmed camera / field-generator fault to Stryker.
Symptom: Software / import fault
- Restart the workstation.
- Confirm the imaging dataset and case licensing.
- Re-import from known-good media / network.
- Check the video outputs to the displays.
- Contact Stryker support with the error.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
An EEPROM chip error code may occur when the catheters are used with CARTO EP Navigation Systems.
- RECALL
Stryker Instruments and Stryker Leibinger GmbH & Co. KG are voluntarily recalling certain serial numbers Thoracic Pedicle Feelers that are used in conjunction with the Stryker Navigation System because the settings on the machine were higher than intended. This change led to increased energy directed onto the tip of the Thoracic Pedicle Feeler which caused material degradation where the laser marks exist. There is the potential for the tip of the Thoracic Pedicle Feeler to break.
- RECALL
Product shipped proximate to or past the expiration date listed on the product label.
- RECALL
Stryker initiated a device recall of the Navigation System II-Cart, Camera Articulated Arm because there is a potential that the weld seam between the main stud and the two flaps on the Articulated Arm was not welded in the correct location, which may result in a potential failure of the arm joint.
- RECALL
Stryker received reports from the field of the impaction plate dissociating/fracturing from the main body of the broach handle.
- RECALL
Multiple software-related malfunctions may occur. The device may suddenly stop working, the screen may freeze, the screen may only be updated very slowly, the unit may not respond to user input, or the unit may only respond to user very slowly.
- RECALL
Circlip component used to suspend flat panel and navigation arm system may become dislodged.
- RECALL
Instructions have been updated to include new warnings regarding percutaneous pin placement during surgery in order to mitigate the risk of femur fractures.
- RECALL
A component of the device is a Dell laptop computer, which contains batteries that are under recall because they can overheat and cause a fire.
- RECALL
Stryker Orthopaedics learned that the T-handles have the potential to not engage and not attach to the reamer properly.
- RECALL
The tracker is not locking adequately to the anchoring pin, resulting in unacceptable movement, which will affected the patient tracker system.
