H10: h3, h6: the device, used in treatment, was not returned for evaluation.Without the device being returned, the issue could not be confirmed.A relationship between the device and reported event has not been established and the root cause of the reported event could not be determined.There was no serial number noted in the initial investigation documents so we are unable to conduct a dhr review as a part of the investigation.A complaint history review was performed and found additional reports of the issue.The failure has been identified in the risk file.The surgical technique guide released at the time of the complaint provides instructions on how to recover to a fully manual procedure in the case the of a navio surgical system failure at any point during the surgical case.A failure can consist of, but is not limited, a system software crash, unrecoverable hardware failure, handpiece failure with no back available, tracker array failure or loss of contact with bone that is unrecoverable, etc.There is no indication in this complaint that the user did not follow the ifu.Our clinical assessment concluded: per complaint details, the device malfunction occurred during surgery but the procedure was changed to manual instrumentation to complete the surgery.Without the requested clinical information a thorough medical investigation cannot be rendered.A factor that could have contributed to the reported event could be a short in the internal cabling of the handpiece being used with the siu.No corrective action or containment is recommended at this time.This issue will continue to be monitored.
