Sternal closure with single compared with double or figure of 8 wires in obese patients following cardiac surgery: A systematic review and meta-analysis.

There is benefit in the use of either double or figure-of-8 sternal wire closure techniques over single wire closure in terms of sternal instability. However, as the studies were limited, larger scale comparative studies are required to provide a solid evidence base for choosing the optimal sternal closure technique in this high risk group of patients.
