As reported, an expired hip stem was inadvertently implanted into the patient.There was no reported patient injury/infection.No revision surgery was reported.The expiration date is located on multiple layers of the packaging.This event is confirmed as a user related error with no malfunction of the device.Review of manufacturing records confirms product was manufactured to specification and there is no indication of a product quality issue with respect to design, manufacturing, or labeling.To date, this is the only reported complaint from this manufacturing lot released for distribution in november 2016.Since the expired product remains implanted in the patient and will not be revised/returned, the packaging of 10 stems that expired on the same date as the subject stem was tested.The results of these packaging tests showed that the packaging still retained sufficient package seal strength and package seal integrity post expiration, implying that the reported stem likely also retained sufficient seal strength and seal integrity post expiration at time of implantation.This product complaint investigation will be included in an ongoing internal capa related to expired or expiring inventory.Should additional information be provided by the healthcare provider, a supplemental mdr will be submitted.
