Abstract

From its resistance to chemical change, modern alloy steel has been called the new noble metal. Soft or annealed stainless steel wire has marked tensile strength, stretches over one third of its length before breaking, and has such resistance to corrosion that when buried in the tissues for prolonged periods of time it remains untarnished and does not give rise to tissue discoloration or local irritation. After three months under a plaster cast, skin sutures of the wire retain their brilliant luster and show no tendency to irritate the tissues. For surgical purposes it may be substituted for the weaker and more brittle silver and bronze wires and replace, with advantage, horsehair, silk, and "dermal" as a fine approximating suture, and silkworm gut as a strong supporting through and through suture. The finer wire may readily be tied in the ordinary square knot without breaking or losing appreciable tensile strength
