    DEVICE INVESTIGATION SUMMARY ¿ ONE TFN Ø10 130° L235 TAN GREEN (PRODUCT NUMBER: 456.325, LOT NUMBER: 7940430, MFG DATE: 13MAR2015; PART 1), ONE HELICAL BLADE F/TFN Ø11 L95 TAN GOLD (PRODUCT NUMBER: 456.304, LOT NUMBER: 7991237, MFG DATE: 25APR2015; PART 2), ONE HELICAL BLADE F/TFN Ø11 L95 TAN GOLD (PRODUCT NUMBER: 456.304, LOT NUMBER: 7991237, MFG DATE: 25APR2015; PART 3), AND ONE INSERT-HANDLE F/TFN (PRODUCT NUMBER: 357.411, LOT NUMBER: 6694869, MFG DATE: 15AUG2011; PART 4) WAS RECEIVED. UPON VISUAL INSPECTION OF ALL COMPLAINT DEVICES THERE ARE CLEAR INDENTATION MARKS THROUGHOUT EACH DEVICE THAT WAS MOST LIKELY CAUSED BY A LOT OF FORCE TRYING TO INSERT THE HELICAL BLADE INTO THE NAIL. PARTS 1 AND 4 (INSERTION HANDLE AND NAIL) ARE COLD WIELDED TOGETHER AND CANNOT BE REMOVED; THIS IS MOST LIKELY CAUSED BY OVER ROTATING THE CONNECTING SCREW CAUSING IT TO BECOME STUCK. FOR PART 1 THERE IS SEVERE DAMAGE AROUND THE PROXIMAL END WHERE THE HELICAL BLADE IS TO BE INSERTED. FOR PART 2 THERE ARE DAMAGED SECTIONS THROUGHOUT THE BLADE. FOR PART 3 THERE ARE MINOR DAMAGE THROUGHOUT THE BLADE. A ROOT CAUSE COULD NOT BE DETERMINED; THE COMPLAINT CONDITION FOR PARTS 1-3 MAY HAVE BEEN CAUSED BY THE NAIL ROTATING AS STATED IN THE COMPLAINT DESCRIPTION AND THE SURGEON TRYING TO A FREE HAND TECHNIQUE TO INSERT THE HELICAL BLADE(S) INTO THE NAIL UNDER POWER CAUSING THE COMPLAINT CONDITION. AND FOR PART 4 THERE ARE INDENTATION MARKS NEAR WHERE THE DRIVING CAP IS SUPPOSED TO ATTACH, THE DAMAGE MAY HAVE OCCURRED AS A RESULT OF HAMMERING ON THE DRIVING CAP TO DRIVE THE NAIL INTO THE PATIENT¿S ANATOMY THROUGH THE USE OF THE INSERTION HANDLE. A ROOT CAUSE COULD NOT BE DETERMINED; IT MAY HAVE BEEN A RESULT OF OVER TORQUE THE CONNECTING SCREW CAUSING THE HANDLE TO BECOME STUCK ONTO THE NAIL. THE COMPLAINT IS CONFIRMED. THE (456.325) DEVICE DRAWING WAS REVIEWED. THE DESIGN HISTORY WAS FOUND TO NOT IMPACT THE COMPLAINT CONDITION. DURING THE INVESTIGATION NO PRODUCT DESIGN ISSUES OR DISCREPANCIES WERE OBSERVED THAT MAY HAVE CONTRIBUTED TO THE COMPLAINT CONDITION. THE RETURNED PART WAS DETERMINED TO BE SUITABLE FOR THE INTENDED USE WHEN EMPLOYED AND MAINTAINED AS RECOMMENDED. DEVICE WAS USED FOR TREATMENT, NOT DIAGNOSIS. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE.
