Product complaint #: (b)(4).Depuy synthes is submitting this report pursuant to the provisions of 21 cfr, part 803.This report may be based on information which depuy synthes has not been able to investigate or verify prior to the required reporting date.This report does not reflect a conclusion by fda, depuy synthes or its employees that the report constitutes an admission that the device, depuy synthes, or its employees caused or contributed to the potential event described in this report.Investigation summary: the complaint device was received and evaluated.The label was returned with the device.The part number and lot number were confirmed.Visually, the outer surface of the sleeve and trocar had striations and nicks, indicating there was a loose fit within the guide frame during use.The trocar interlocking pin is still intact.The sleeve and trocar were jammed together and could not separate, indicating a ¿cold weld¿ occurred during drilling, thus confirming this complaint.Upon further observation the sleeve was discovered not interlocked with the trocar pin, indicating a poor assembly prior to use, which could¿ve created a loose fit resulting to the failure reported.Furthermore, another possible root cause for this type of failure could be that the guide frame was out of alignment with the sleeve which could cause the frame to bind up with the sleeve/trocar resulting in cold welding of the two parts.This failure can be attributed to user technique.The dhr review indicated that this batch of devices were processed without incident, therefore, there is no evidence of manufacturing anomalies on the records reviewed.Furthermore, a review into the depuy mitek complaints system revealed one dissimilar complaint for this lot of devices that were released to distribution.And at this time no corrective action is required, and no further action is warranted.However, depuy synthes mitek will continue to track any related complaints within this device family as a means of monitoring the extent with which this complaint is observed in the field.Udi: (b)(4).
