Event Description

It was reported that the patient was originally implanted with one (1) titanium ti distal femur liss plate and eight (8) screws on an unknown date to treat a distal femur fracture.On (b)(6) 2016, the patient returned to the operating room to undergo the scheduled hardware removal surgery.During the surgery, while removing two (2) of the titanium locking screws with large hexagonal screwdriver shaft, the tip of the screwdriver shaft broke off in the screw head.Surgeon then used second large hexagonal screwdriver shaft to remove the screw and the tip of a second large hexagonal screwdriver shaft also broke off in the screw head.Both the broken tips of the screwdriver shafts were retrieved and no piece of the instruments remained in the patient.As per surgeon, these two (2) titanium locking screws were too tight and cold-welded into the plate.Therefore, surgeon first drilled out the heads of the screws to get the plate off and then removed the screw shafts with screw removal set.The tissue was cleaned and all fragments were completely removed from the patient.All the hardware was removed with no further complications.There was surgical delay of 10 minutes due to the reported event.Third screwdriver shaft was readily available to complete the procedure.Surgery was successfully completed with no patient harm.Patient status reported as stable.Concomitant devices reported as: titanium distal femur liss plate 9 holes/236mm-left (part # 422.345, lot # unknown, quantity-1), locking screws (part # unknown, lot # unknown, quantity 6).This is report 4 of 4 for (b)(4).
