Additional Manufacturer Narrative
It was reported that a revision surgery was performed due to pain, fluid collection and metal ion levels.As of today, the implanted device used in treatment has not been returned for evaluation.A review of the historical complaints data for the femoral head was performed using batch number, part number and the reported failure modes to evaluate patterns of repeated failures or defects.Similar complaints have been identified for device, and this failure will continue to be monitored.In the absence of the actual device, the production records were reviewed for the device reportedly involved in this incident.All released devices involved met manufacturing specifications upon release for distribution.The 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 product and similar complaint events was performed.Following the review, no prior applicable escalation actions were identified.The available medical documents were reviewed.Based on the reported symptoms it cannot be concluded that the events/clinical reactions of pain, fluid collection around implants, and metal ion levels in blood were associated with a mal-performance of the implant.The patient impact cannot be determined at this time.No further clinical assessment is warranted at this time.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 device or additional information be received, the complaint will be reopened.Based on this investigation, the need for corrective and preventative actions is not indicated.H11: corrected information in h6 (health effect - clinical code).
