The fastsystem sterile field post (4080) was returned for evaluation: the device history record (dhr) was reviewed, and no anomalies related to the reported failure were observed.Failure analysis: evaluation found that the clamp jaw of the sterile field post was unstable when mounted on the test rail.The bolt had become flat at the bottom and must be replaced along with the washers.Root cause analysis: the complaint reported by the customer was confirmed as valid.Based on the evaluation by integra service and repair, the root cause was most likely use-error (closing the clamp with nothing inside).No manufacturing, workmanship, or material deficiency was identified for correction as a result of this complaint investigation.
