Manufacturer Narrative

It was reported that the patient experienced increasing metal levels, pain, thickening, inflammation and a pseudotumor.This adverse event was treated with a revision surgery on (b)(6) 2021.Patient's current health status is unknown and the devices, used in treatment, were not available for analysis.As no device part and batch numbers were provided for investigation, a complaint history review, manufacturing record review, device labelling/instructions for use review could not be performed.If more information is received, this investigation will be reopened.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.A risk management review was performed for the acetabular cup and femoral head.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.The clinical information provided, of the black crevice assisted corrosion material and debris around the taper, and pseudotumor 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.Without return of the actual devices or further information we cannot further investigate the details supplied in this complaint, our investigation remains inconclusive, and a definitive root cause cannot be determined.Based on the limited information provided we are unable to speculate on specific factors known to contribute to the alleged fault.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.

Event Description

It was reported that, after a right bhr-tha system had been implanted on (b)(6) 2009, the patient experienced a failed metal-metal implant and adverse local reaction including increasing metal levels, pain, thickening, and inflammation of the bursa, and a pseudotumor.This adverse event was treated by performing a revision surgery on (b)(6)2021.Patient¿s current health status is unknown.

Manufacturer Narrative

B5, h3, h6: it was reported that a right hip revision surgery was performed due to failed metal-metal implant and adverse local reaction including increasing metal levels, pain, thickening, and inflammation of the bursa, and a pseudotumor.As of today, the implanted devices, all of which were used in treatment are not accessible for testing.Without a definitive batch number, a complete review of the historical complaints data cannot be performed for the devices.A review of historical complaints data was performed using the part numbers and the reported failure modes to evaluate patterns of repeated failures or defects.Similar complaints have been identified for the hemi head.As no device part number was provided for the cup nor the sleeve, a complaint history review could not be performed.If more information is received, this investigation will be reopened.As no device batch numbers were provided for investigation, manufacturing record review could not be performed.If more information is received, this investigation will be reopened.The review of the current 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.The clinical information provided, of the black crevice assisted corrosion material and debris around the taper, and pseudotumor 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.Based on the information provided, further investigation of the reported complaint cannot be carried out and remains inconclusive.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.

Manufacturer Narrative

H3, h6.It was reported that, after a right bhr-tha system had been implanted, the patient experienced a failed metal-metal implant and adverse local reaction including increasing metal levels, pain, thickening, inflammation of the bursa and a pseudotumor.As of today, the devices, which were used in treatment, have not returned for evaluation.As no batch numbers were provided and no part numbers were provided for the cup and sleeve, a full complaint history review of the devices could not be performed.A review of the historical complaints data for the hemi head was performed, 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 for the part number and the reported/related failure mode.This will continue be monitored through usual monthly complaint trending.It should be noted that this device is no longer sold.The dhr was task closed as reasonable effort to obtain a lot/batch/serial number have not been successful.Should the lot/batch/serial number become available at a later date then the dhr task will be re-opened and completed.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 alleged failure modes and associated risks have been anticipated within the risk file and the anticipated risk level is still adequate.A review of historic quality escalations 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.The right revision operative report noted, "thin-walled pseudotumor and some black crevice assisted corrosion material and debris around the taper and in the taper sleeve".Also that "the patient reported that he still suffers from hip pain and was diagnosed with right hip bursitis".The reported increasing metal levels, pain, pseudotumor and possible righty hip joint effusion may be consistent with metal debris.However, the clinical root cause of the reported events/clinical reactions cannot be confirmed, and it cannot be concluded that the reported events/clinical reactions were associated with a mal performance of the implant.The reported post-revision pain is likely related to the reported bursitis and is not associated with a mal performance of the implant.The patient impact beyond the revision cannot be determined with the provided information.Based on the information provided we cannot further investigate the complaint 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.If the products or additional information become available in the future, this case will be reopened.Based on this investigation the need for corrective and preventative action is not indicated.
