It was reported that, after a bhr-tha construct had been implanted on the patient's left hip on (b)(6) 2011, the patient experienced local signs of metallosis, elevated metal ion levels in blood and pain.This adverse event was treated by a revision surgery on (b)(6) 2022, in which a r3 44mm id us cocr lnr 56mm and a hemi head44mm were explanted and replaced with an oxinium head and a xlpe liner.Intraoperatively, the soft tissues show signs of metallosis and trunnionosis.The patient's current health status is unknown.All available information has been disclosed.If additional information should become available, a supplemental report will be submitted accordingly.

Manufacturer Narrative

H3, h6: it was reported that left hip revision surgery was performed due to metallosis and elevated metal ion levels.The procedure removed the metal on metal liner, hemi head and modular sleeve.Intraoperatively, the soft tissues showed signs of metallosis and trunnionosis.The devices, used in treatment, were not returned for analysis.A review of the historical complaints data for the devices concerned was performed using batch numbers to evaluate patterns of repeated failures or defects over the lifetime of the product and using part numbers and the reported failure modes to evaluate patterns of repeated failures or defects in a timeframe prior 12 months as of the complaint aware date.Other complaints were identified to involve these r3 liner, hemi head and modular sleeve batches.Other similar complaints were also identified for the r3 liner and hemi head part numbers and the reported/related failure mode.No other complaints were identified for the modular sleeve part number and the reported/related failure mode.These devices are no longer sold, therefore no action is to be taken, however trends 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.All released devices involved met manufacturing specifications upon release for distribution.Review of the product ifu found adequate warnings and precautions in relation to the alleged failure modes.A risk management review was performed.The alleged failure modes and associated risks have been anticipated within the risk file and the anticipated risk level is still adequate.No further actions are required at this time.A review of historic escalation actions related to the products and similar complaint events was performed.Following the review, prior applicable escalation actions were identified and confirmed to reduce associated risks as far as possible.No further escalation actions are required.The available medical documents were reviewed.Based on the reported symptoms it cannot be concluded that the events/clinical reactions (elevated metal ions, pain, and intraoperative findings of metallosis and trunnionosis) were associated with a mal-performance of the implant.The patient impact cannot be determined at this time.Based on the limited available information and lack of operative or medical reports, we cannot confirm the reported complaint, and without further information our investigation remains inconclusive and a definitive root cause cannot be determined.Specific factors known to contribute to the alleged fault are excessive physical activity levels, unreasonable stress on replacement system, excessive patient weight, trauma to the joint replacement, loosening of components may increase production of wear particles and accelerate damage to the bone.Should the devices or additional information be received, the complaint will be reopened.Based on this investigation, the need for corrective and preventative actions is not indicated.
