Event or Problem Description
It was reported the surgeon experienced difficulty tightening the locking mechanism onto the blade surface.The statis locking screwdriver assembly was passed through the insertion handle, but it was uncertain whether it had fully engaged through the cannulated connecting screw.The surgeon suspected it was not properly seated in the hexagonal recess of the lock drive, as clockwise advancement was not possible.Multiple attempts were made using both the flexible screwdriver (03.037.028) and the 5 mm hexagonal screwdriver shaft (03.027.029), but without success.The surgeon then attempted a few light mallet taps to help engage the lock drive, which also failed.The surgeon decided to remove the nail for inspection.However, when attempting to detach the hexagonal screwdriver shaft, it could not be disconnected from the insertion handle.As a result, the entire construct (hexagonal screwdriver shaft, insertion handle, and nail) had to be removed as one piece.The surgeon proceeded with a second instrument set and a new nail.Using the same steps, the surgeon was able to advance the locking mechanism successfully with the 5 mm flexible screwdriver passed through the connecting screw and insertion handle, ensuring proper engagement with the locking mechanism.Procedure was completed successfully with a 15 minute surgical delay.A second instrument set was used to complete the surgery.
