Manufacturer Narrative

Internal complaint reference: case (b)(4).

Event Description

It was reported that, after left r3-tha was performed on (b)(6) 2009 due to hip arthritis, the patient experienced pain, metallosis and trunionosis.This adverse event was treated with a revision surgery on (b)(6) 2021, in which significant metallosis in the hip was found.Most of metallosis was generated between the cup and metal liner.In addition, a significant pseudotumor was observed, which was debrided.Furthermore, the acetabular component was retroverted by few degrees.Patient's current health status is unknown.

Manufacturer Narrative

H3, h6: it was reported that a left hip revision surgery was performed.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 hemi head and r3 liner 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 similar complaints were identified to involve this batches and for the part numbers and the reported failure modes.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.With the information provided the clinical root cause of the reported metallosis cannot be confirmed.However, it is unknown if the retroverted acetabular component led to accelerated wear and the reported metallosis.The patient impact beyond the 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.
