    Description of Event or Problem · 1

    THIS REPORT IS BEING FILED AFTER SUBSEQUENT REVIEW OF THE FOLLOWING JOURNAL ARTICLE, FERNANDES HJA, SAKAKI MH, SILVA JS, REIS FB, AND ZUMIOTTI AV. (2006). COMPARATIVE MULTICENTER STUDY OF TREATMENT OF MULTI-FRAGMENTED TIBIAL DIAPHYSEAL FRACTURES WITH NONREAMED INTERLOCKING NAILS AND WITH BRIDGING PLATES. CLINICS. 61(4):333-338. THIS WAS A PROSPECTIVE, RANDOMIZED STUDY TO COMPARE PATIENTS WITH CLOSED, MULTI-FRAGMENTED TIBIAL DIAPHYSEAL FRACTURES TREATED USING ONE OF TWO FIXATION METHODS UNDERTAKEN DURING MINIMALLY INVASIVE SURGERY: NONREAMED INTERLOCKING INTRAMEDULLARY NAILS OR BRIDGING PLATES. FORTY-FIVE PATIENTS WERE STUDIED; 22 PATIENTS WERE TREATED WITH BRIDGING PLATES, 23 WITH INTERLOCKING NAILS WITHOUT REAMING. THE STUDY PERIOD WAS FROM (B)(6) 2002 TO (B)(6) 2003. THE FOLLOW-UP PERIOD VARIED BETWEEN 6 MONTHS TO ONE YEAR. THE BLOCKED INTRAMEDULLARY NAILS USED WERE SYNTHES AO UNIVERSAL STEEL NAILS INTRODUCED WITH NO MEDULLARY CHANNEL REAMING. THE AUTHORS USED A NARROW PLATE FOR LARGE FRAGMENTS (4.5 MM SYNTHES (B)(4)). IN THE GROUP TREATED WITH INTRAMEDULLARY NAILS, 4 PATIENTS WERE WOMEN AND 19 WERE MEN, WHILE IN THE GROUP TREATED WITH A BRIDGING PLATE, 3 WERE WOMEN AND 19 WERE MEN. THE HEALING TIME FOR PATIENTS WHO RECEIVED NAILS WAS SIGNIFICANTLY LONGER, BY AN AVERAGE OF 4.30 WEEKS, THAN THE HEALING TIME FOR THOSE WHO RECEIVED BRIDGING PLATES. FOUR PATIENTS (NUMBERS 1, 3, 7, AND 8) WHO WERE TREATED WITH INTRAMEDULLARY NAILS EXPERIENCED DELAYED HEALING. THIS REPORT IS FOR AN UNKNOWN NAIL. THIS IS REPORT 4 OF 4 FOR COMPLAINT (B)(4). THIS MEDWATCH PERTAINS TO PATIENT NUMBER 8 WHO EXPERIENCED DELAYED HEALING.
