    Narratives

    Additional Manufacturer Narrative · 1

    A MANUFACTURING EVALUATION WAS CONDUCTED. NO PART NUMBERS NOR LOT NUMBERS WERE PROVIDED. THIS SCREW PIECE IS COMPRISED OF A WHOLE HEAD AND APPROXIMATELY THREE THREADS OF THE SHAFT. THE PIECE IS 11.57MM LONG. THE PROFILE OF THE HEAD, TYPE OF THREAD, AND THREAD PROFILE SUGGEST THAT THIS IS A MEMBER OF THE 214.8XX FAMILY OF SCREWS. THE HEAD IS LASER ETCHED. THE PART WAS MADE PRIOR TO (B)(4) 2011. THE HEX IS IN GOOD CONDITION AS IS THE TOP OF THE HEAD. THE BAND HAS, WHAT APPEARS TO BE, AN IMPACT/WEAR MARK. THERE IS LIGHT GALLING JUST BELOW THE BAND ON THE BOTTOM OF THE HEAD. THERE IS ALSO AN IMPACT OR WEAR MARK WITH DISPLACED MATERIAL AT THE FIRST THREAD. THERE ARE ONLY THREE THREADS REMAINING ON THE SHAFT. DUE TO THE TYPE AND EXTENT OF DAMAGE INCURRED, AND ALSO BECAUSE NO PART NOR LOT NUMBERS WERE PROVIDED, NO CONCLUSION CAN BE DETERMINED FROM A MANUFACTURING STANDPOINT. NOTE: BLANK FIELDS ON THIS FORM INDICATE INFORMATION THAT IS UNKNOWN, UNAVAILABLE OR UNCHANGED. PLACEHOLDER.

    THIS DEVICE IS USED FOR TREATMENT, NOT DIAGNOSIS. NO X-RAYS WERE PROVIDED, BUT THE CONSTRUCT WAS ON A HUMERUS. THE TYPE OF FRACTURE WAS NOT DISCLOSED. THE CONSTRUCT HAD ALL HOLES FILLED - 8 SCREWS, 8 HOLE PLATE - AND THE PLATE WAS A BROAD PLATE. THE PLATE CONSTRUCT - BROAD PLATE, ALL HOLES FILLED - MAY HAVE BEEN TOO STIFF FOR THE NATURE OF THE FRACTURE WHICH COULD HAVE LEAD TO THE NON-UNION.
