Surface alterations and fractured ends of sternal wires were inspected and analyzed. METHODS: Eight fractured and 12 non-fractured wires extracted from five patients (closure method: figure-of-eight or straight twisted; two without and three with mediastinitis) with mean implantation interval of 13.2+/-4.2 days (range 8-20 days) were studied by various techniques. The extracted wires were cleaned and the fibrotic tissues were removed. Irregularities and fractured ends were assayed by scanning electron microscopy and energy dispersive X-ray analysis (EDXA). RESULTS: All examined fractured wires showed the presence of severe transversal cracks and crevice corrosion. EDAX revealed aluminum oxide inclusion on the fractured surface. CONCLUSIONS: The synergic effect of stress and poor wire quality could be the precursors of material failure for the sternal wire. ------>tmu_sno=None ------>sno=13863 ------>authors2=Shih CM ------>authors3=Su YY ------>authors4=Lin SJ ------>authors5= ------>authors6= ------>authors6_c= ------>authors=Shih CC ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Potential risk of sternal wires. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=5 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2004 ------>submit_flag=None ------>publish_month=5 |
