(b)(4).

Event Description

Bilateral patient.Plaintiff underwent medically-indicated revision of the bhr right hip implants on (b)(6) 2011.The patient revision surgery was performed due to unknown reasons.Only the head was explanted.A conversion to a bhr-tha system was performed.

Manufacturer Narrative

It was reported that right hip revision surgery was performed on a bilateral patient.During the revision, the bhr head was removed.The bhr cup remained implanted.As of today, the implanted devices, all of which were used in treatment, and additional information have been requested for this complaint but have not become available.A review of the complaint history for the bhr head and bhr cup was performed using batch numbers in search of similar recurring reports for the products during their lifetimes.No other similar complaints were identified for the bhr head.Similar complaints have been identified for the bhr cup and this will continue to be monitored.In the absence of the actual devices, the production records were reviewed for the devices reportedly involved in this incident.Device history record review confirmed that all released parts met specifications applicable at the time of production.Review of the product ifu found adequate warnings and precautions in relation to the alleged failure modes.A risk management review was performed.No additional risks were identified as result of the reported event and no further actions are required at this time.The available medical documents were reviewed.For the bilateral two stage revisions; the clinical information provided, of the reported elevated metal ion levels, the pseudotumor, and the necrotic tissue may be consistent with a reaction to metal debris.However, the source and the root cause cannot be determined with the available documentation.It cannot be concluded that the reported clinical findings are associated with the implant failure versus the reported infection.The cultures that positive for bacillus species on the left and mrse on the right were likely an hematogenous infection without return of the actual devices or further information we cannot further investigate or confirm the details supplied in this complaint, and our investigation remains inconclusive.If the products or additional information become available in the future, this case will be reopened.No preventative or corrective action has been initiated as a result of this investigation.
