Investigation revealed that there was no system malfunction.The purpose of this investigation is to evaluate the risk associated with the identified failure mode of misplaced implants or tools for excelsiusgps.The software shows that l4-l was placed on a steep slope which may cause the implant to skive depending on instrument technique.There was no indication of excessive deflection forces on the end effector; however we do see a large quantity of warnings for ee visibility and camera movements.Skiving can lead to the misplacement of screws.The anticipated overall risk is moderate.The severity observed did not exceed the anticipated severity.The observed overall risk level is moderate, which does match the anticipated risk level; therefore, the overall risk of the system has been maintained and there is no further investigation required.The cause of the reported issue was traced to user technique.
