Combined use of single and double-cross steel wires for closure of midlinesternotomy

Background. We describe an improved technique for sternal closure which is performed using combined single and double-cross steel wires. We made a mec hanical study of these single and double-cross shapes considering the effec ts of applied transverse and longitudinal shearing forces. Methods. We used this technique in 80 patients who underwent coronary surge ry with the use of bilateral internal mammary arteries. Results. Among them no major wound complications occurred, and in all cases a firm stabilization of the sternum was achieved. Conclusions. We therefore consider this technique of sternal closure easy, safe and effective, also in patients considered at risk for sternal dehisce nce.
