    Narratives

    Additional Manufacturer Narrative · 1

    A PD INVESTIGATION SUMMARY WAS PERFORMED. THE INVESTIGATION OF THE COMPLAINT ARTICLES HAS SHOWN THAT: DEVICE WAS USED FOR TREATMENT, NOT DIAGNOSIS. THE DEVICES WERE RETURNED AND REPORTED TO HAVE BROKEN DURING SURGERY INSIDE THE PATIENT. THIS CONDITION IS CONFIRMED; ALL FOUR PRONGS OF THE FLEXIBLE SHAFT HAVE BROKEN OFF, THE REAMER HEAD IS MISSING A LARGE CHUNK FROM THE PROXIMAL PORTION OF THE DEVICE, AND THE TIP OF THE REAMING ROD WAS RETURNED HAVING BROKEN APPROXIMATELY 45MM FROM THE DISTAL TIP. IT IS LIKELY THAT THE REAMING ASSEMBLY ENCOUNTERED SIGNIFICANT RESISTANCE WHILE REAMING IN ADDITION TO NUMEROUS YEARS OF USE LEADING TO THIS COMPLAINT CONDITION. THE 352.085 REAMER HEAD WAS MANUFACTURED IN 8/2005 AND IS OVER NINE YEARS OLD. THE 352.040 WAS MANUFACTURED IN 10/2012 AND IS OVER TWO YEARS OLD. THE CONDITION OF THE RETURNED DEVICE DOES AGREE WITH THE COMPLAINT DESCRIPTION. WHETHER THE COMPLAINT CONDITION FOR THIS DEVICE CAN BE REPLICATED IS NOT APPLICABLE FOR THIS CONDITION. THE COMPLAINT CONDITION FOR THE 352.040 LOT NUMBER 8113661 5.0MM FLEXIBLE SHAFT, 352.085 LOT NUMBER 2143090 MEDULLARY REAMER HEAD, AND 2.5MM REAMING ROD WITH BALL TIP WAS LIKELY CAUSED BY YEARS OF USE AND POSSIBLY DUE TO RESISTANCE ENCOUNTERED WHILE REAMING; HOWEVER, THIS COMPLAINT IS NOT A RESULT OF ANY DESIGN RELATED DEFICIENCY. 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.
