The received device was forwarded to commercialized product development for evaluation.A worldwide complaint database search found no other reported incident(s) against the provided product/lot combination(s) since release for distribution.Review of the device history records did not reveal any related manufacturing deviations or anomalies on the provided product and lot combination.The bent tab would have made insertion difficult, preventing proper seating and therefore the locking problem can be confirmed.However, since it is not possible to determine how the anterior tab got bent, the root cause of the bent locking tab cannot be definitively determined.Corrective action was not indicated.Depuy considers the investigation closed at this time.Should the additional information be received, the information will be reviewed and the investigation will be re-opened as necessary.
