[New method for closure of median sternotomy: usefulness of barbed staple].
In this report, 15 cases using straight staple (group A) and 35 cases using barbed staple (group B) were compared for the purpose of investigating efficacy for median sternal closure. The staples were placed by a Stapilizer powered metaphyseal staple system following partial transsternal fixation with two wires. As a means of assessing the status of back out, which is a major cause of poor fixation, the back out rate (BOR) was measured on lateral sternal radiographies. The average BOR was found to be 33.8% in group A and 21.2% in group B (p < 0.001). Barbed staples seemed to be more useful for sternal fixation than straight staples. This method of applying barbed staples had the advantages of speed, ease of insertion and noninvasion of the retrosternal region. It should be recommended in cases with severe adhesion of the retrosternal region after coronary operation.
