The reported event could not be confirmed, since the device was found to be fully functional.A device inspection revealed the following: the returned tissue protection sleeves show obvious signs of usage evident by worn off surfaces and scratches.The only significant observation was that the tip of the sleeves was slightly worn out, one more than the other.However, it didn't affect the insertion of the k-wire sleeves in any way.A pre-surgical functional test was performed with the returned devices and some sample devices(k-wire & recon sleeve).It was observed that the k-wire sleeves and the tissue protection could be easily assembled together and with the target device as well without any jamming.The targeting accuracy was also given.The sleeve clamping feature is as intended.Thus, the alleged issue could not be reproduced and could not be confirmed.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.No indications of material, manufacturing or design related problems were found during the investigation.A review of the labeling did not indicate any abnormalities.Based on the above investigation, the issue is deemed to be user related since the alleged issue could not be reproduced.The function of target device along with all the sleeves was given as intended.If any additional information is provided, the investigation will be reassessed.
