Can legal mdl it was reported that a revision surgery was performed on the patients left hip due to pain and high metal ion levels.The patient outcome is unknown.

Manufacturer Narrative

It was reported that left hip revision surgery was performed.During the revision, the modular head, r3 liner and modular sleeve were removed.The r3 shell and stem 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 r3 liner and modular head 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 r3 liner.Similar complaints have been identified for the modular head.However, as the device is no longer sold, no action is to be taken.In the absence of the actual devices, the production records were reviewed for the devices reportedly involved in this incident.All the released devices involved met manufacturing specifications 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.The available medical documents were reviewed.Although it was reported that the patient had elevated metal ion levels, neither the levels nor the lab reports were provided for review.Without the supporting lab/pathology results, imaging, and/or the analysis of the explanted components, the root cause of the reported pain, elevated metal ion levels and trunnionosis cannot be confirmed and it cannot be concluded that the reported clinical reactions were associated with a mal-performance of the implant.The patient impact beyond the pain, revision, and expected transient post-op convalescence period cannot be determined.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.

Manufacturer Narrative

H3, h6: it was reported that a left revision surgery was performed due to pain and high metal ion levels.The r3 metal liner, modular head and sleeve were explanted.As of today, the implanted devices, all of which were used in treatment have not been returned for evaluation.A review of the historical complaints data for the modular head and sleeve was performed using batch numbers, part numbers and the reported failure modes to evaluate patterns of repeated failures or defects.Similar complaints have been identified for the modular head and sleeve.However, as the devices are no longer sold, no action is to be taken.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 required.The available medical documents were reviewed.Without the supporting lab/pathology reports, imaging, and/or the analysis of the explanted components, the root cause of the reported pain, elevated cobalt levels and trunnionosis cannot be confirmed and it cannot be concluded that the reported clinical reactions were associated with a mal-performance of the implant.The patient impact beyond the pain, revision, and expected transient post-op convalescence period cannot be determined.Based on the available information we can confirm the reported complaint, however 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.

Event Description

It was reported that, after an r3-tha construct had been implanted on (b)(6) 2011, the patient experienced pain and pain and had high metal ion levels.A revision surgery was performed on (b)(6) 2018: liner, head and sleeve were explanted, while the acetabular cup and the stem were left in-situ.
