Additional Manufacturer Narrative
The complaint couldn't be confirmed, since the returned image for evaluation don't match the alleged failure.Upon further investigation of the ct scans by healthcare professionals the following was observed: the quality is poor and the possibilities to assess the are therefore limited.The clinical information is also limited and therefore i can only guess, that there is loosening of the talar component with posterior subsidence.Radiolucence and cysts cannot be identified clearly, though.There is also no assessment possible regarding the underlying cause for the failure.Overall, i would say that due to lack of clinical information and poor imaging a meaningful evaluation is not possible here.Failure of total ankle replacement tar over time is a known complication.In case of a planned revision procedure a medical opinion aiming to determine the root cause of the failure is part of the internal investigation process.Sufficient radiological and clinical information must be provided to enable a meaningful clinical assessment and to identify possible causes of failure.In cases where a ct scan is the only available clinical source, the assessment is limited.No conclusive statement can be provided, because key clinical information e.G.Clinical status, exact symptoms and range of motion of the patient, assessment of the treating physician is missing.The root causes of radiographic findings such as radiolucent areas and bone cysts are often complex and multifactorial and cannot be determined scientifically without this decisive evidence.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.More detailed information about the complaint event must be available in order to determine the root cause of the complaint event.If the device is returned or if any additional information is provided, the investigation will be reassessed.
