Manufacturer Narrative

The reported event could be confirmed since the device was returned and matches the alleged failure mode.The device inspection revealed the following: the received nail is completely broken in the webs of the proximal drill hole for the lag screw.On all breakage surfaces of both left and right web features of a fatigue fracture are visible (evident by the presence of lines of rest).Plastic deformation was not found.Areas with signs of friction / seizing [bearing points of lag screw] are visible at both medial and lateral edge of the proximal part.Similar areas were identified at the distal medial edge.The countermarks were found on the lag screw in the areas with corresponding friction signs and worn edges due to poor positioning of lag screw.Based on review of the x-rays that were provided, as well as other patient information, the root cause was attributed to a user-patient related issue.The failure was caused by poor positioning and consequent instability of the lag screw leading to additional stress on the nail as evident by the bearing marks.This additional stress caused weakening of nail and ultimately initiated a fracture in a fatigue manner.When the patient fell, it finally broke the nail completely.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.If any further information is provided, the complaint report will be updated.
