    Narratives

    Additional Manufacturer Narrative · 1

    DEVICE IS USED FOR TREATMENT, NOT DIAGNOSIS. THE RETURNED AIMING ARM WAS MANUFACTURED IN APRIL 2011 AND IS OVER 2 YEARS OLD. THE RETURNED BLADE GUIDE SLEEVE WAS MANUFACTURED IN APRIL 2011 AND IS OVER 2 YEARS OLD. THE RETURNED HELICAL BLADE INSERTER WAS MANUFACTURED IN JUNE 2012 AND IS APPROXIMATELY 1 YEAR OLD. THE BUTTRESS COMPRESSION NUT LISTED IN THIS COMPLAINT WAS NOT RETURNED FOR EVALUATION. BASED ON LOT NUMBER, IT IS KNOWN THAT IT'S DATE OF MANUFACTURE WAS MAY 15,2003 AND THEREFORE IT IS OVER 10 YEARS OLD. COMPLAINT WAS RECEIVED STATING PARTS WERE DIFFICULT TO DISCONNECT FOR CLEANING AND STERILIZATION AND HAD TO BE FORCED APART. THE COMPLAINT CONDITION COULD BE REPLICATED WITH THE HELICAL BLADE INSERTER BUT NOT WITH THE OTHER PARTS. THIS COMPLAINT CONDITION IS CAUSED WHEN THE HAMMER MISSES THE HEAD OF THE COUPLING SCREW, THE EARS OF THE INDICATOR ARE ACCIDENTALLY HIT BY THE HAMMER. THIS MAY CAUSE THE PIN IN THE INDICATOR TO BE DAMAGED AND THEREFORE THE INDICATOR MAY SPIN FREELY OR IT MAY BECOME JAMMED. THIS IS DUE TO A KNOWN TECHNIQUE ISSUE RELATING TO THE USE OF THE HAMMER. THIS CAN BE CAUSED IF THE HAMMER MISSES THE HEAD OF THE HELICAL BLADE COUPLING SCREW AND INSTEAD HITS THE EARS OF THE INDICATOR. IT DOES NOT CAUSE A LOSS OF FUNCTION DURING THE CASE, AND IT DOES NOT POSE ANY SAFETY OR HEALTH CONCERNS. THE PURPOSE OF THE INDICATOR IS TO CAPTURE THE GOLD HANDLE ON THE INSERTER. IF THE TOP SPINS FREELY IT IS STILL HELD IN PLACE AND DOES NOT FALL OFF OF THE HELICAL BLADE INSERTER AND THEREFORE THE CASE CAN BE COMPLETED WITHOUT INCIDENT. IF THE INDICATOR BECOMES JAMMED IT STILL CAPTURES THE GOLD HANDLE AND THE CASE CAN BE EASILY COMPLETED. THE TROCHANTERIC FIXATION NAIL RISK ANALYSIS ADEQUATELY ADDRESSES THIS COMPLAINT CONDITION AS LESS SEVERE. SPECIFICALLY, THE RISK ASSOCIATED WITH THE 12TH HAZARD LISTED UNDER INSTRUMENTATION ON ASSEMBLY INDICATOR TOP OF BLADE INSERTER EITHER BEING JAMMED OR FREELY SPINNING DUE TO SURGEON HAMMERING ON THE EARS OF THE INDICATOR INSTEAD OF THE COUPLING SCREW HEAD IS ASSESSED AS LESS SEVERE WITH A MARGINAL SEVERITY OF HARM 2 AND AN UNLIKELY PROBABILITY OF OCCURRENCE 2 WITH POSSIBLE HARMS LISTED AS INDICATOR FREELY SPINNING: DOES NOT INDICATE ORIENTATION OF BLADE, AND INDICATOR JAMMED: CANNOT DISASSEMBLE FOR CLEANING. THE COMPLAINT CONDITION OF STICKS/JAMS/STUCK IS CONFIRMED DURING THIS EVALUATION ONLY FOR THE HELICAL BLADE INSERTER. THE COMPLAINT CONDITION IS CAUSED BY INADVERTENT HAMMER BLOWS TO THE INDICATOR. THE DESIGN IS ADEQUATE FOR ITS INTENDED USE AND DID NOT CONTRIBUTE TO THIS COMPLAINT CONDITION. PLACEHOLDER.
