This paper seeks to classify and understand the mechanisms of surface damages and fracture mechanisms of sternal wires. Explanted stainless steel sternal wires were collected from patients with sternal dehiscence following open-heart surgery. Corrosion pits were found on the surface of the explanted wires. EDAX and X-ray mapping examinations revealed diminution of nickel concentration in the severe corroded pits. The synergic effect of a hostile environment and the stress could be the precursors to failure.
