G3: report source, foreign - event occurred in poland.E1: postal code: (b)(6).Products have been returned to biomet uk ltd for evaluation and forwarded to a research engineer for investigation.Summary of investigation: a taperloc cocr stem with a j-hook stem extractor still attached was received for examination.The stem was revised after 2 months and 24 days.As described in the complaint description, loosening was initially suspected as the reason for revision.However, after receiving further information from the surgeon it was established that the patient was admitted to the hospital due to sepsis.The surgeon decided to remove the implant in an attempt to cure the sepsis.Moreover, the complaint description states that when the patient was revised there was absolutely no indication that the implant could in any way contribute to the state of the patient (there was no signs of infection, loosening or other problems around the implant).The implant was removed and replaced with spacer (even though there was no evidence that the implant had any negative effect).Visual examination of the stem indicates an overall good condition.Minor damages observed on the component were likely caused by the extraction procedure and the contact of the stem with the j-hook extractor.Surgical reports and radiographs from the primary and revision surgery have not been provided for review.Additionally, patient information such as age, height, and weight have not been provided due to country regulations.Review of the device mhrs confirmed that the stem had been manufactured and sterilised correctly.No evidence was found that the taperloc stem malfunctioned during use or that it could have caused the reported sepsis in this patient.Conclusion: a taperloc cocr cemented stem was revised after 2 months and 24 days.The analysis of the returned stem with a j-hook extractor did not find any evidence that the taperloc stem malfunctioned during use or that it could have caused the reported sepsis.Risk assessment: from the information provided, root cause cannot be confirmed and the complaint indicates that harm was not related to the device, therefore, a risk assessment cannot be performed based on the information provided.Corrective and preventive actions taken: no actions needed at this time.This complaint was determined not to be a new confirmed quality or manufacturing issue.Complaints are monitored through monthly complaint review (reference (b)(4)) in order to identify potential adverse trends.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
