The reported event could not be confirmed due to the lack of additional clinical information.Upon further investigation of the ct scans by healthcare professionals the following was observed: ¿the talus shows a little bit of cysts posteriorly, there is no clear radiolucence as an indicator for loosening.There is a potential loosening or subsidence, here-but that could be better visible with the comparison of x-rays directly after the implantation and the latest x-rays.The surgeon assumes that the components could be loose.This cannot be confirmed with certainty using the ct images.As a certain amount of pain and restricted movement are described as the main clinical symptoms, i believe that a soft tissue problem could also be the cause of the pain/reduced range of motion.¿ more detailed information about the complaint event as well as the affected device must be available in order to determine the root cause of the complaint event.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.If the device is returned or if any additional information is provided, the investigation will be reassessed.
