Per (b)(4) final report.The reported devices were returned to corin for examination, which allowed us to confirm the failure mode.The relevant device manufacturing records were identified and reviewed.The impactor was supplied in august 2021, and the cup holder attachment was supplied in march 2022.Both devices conformed to material and dimensional specifications at the time of manufacture.Based on the investigation, the condition of the first couple of threads suggest that it never engaged with the female thread correctly.When the surgeon impacted the cup the first time, this probably damaged the threads and caused the cup holder attachment stayed expanded.In this hypothesis, the root cause is probably due to a misuse.Based on this, corin now consider this case closed.A monitoring will be done on this failure mode.The submission of this report does not constitute that the device reporting entity, entity's representative or distributor caused or contributed to this event.
