The fatigue resistance of stainless-steel orthopaedic wire was investigated in samples of commercially available (1.2 mm, 16-gauge) stainless-steel wire. The wires were subjected to various types of notching, bending, twisting, and knotting and were then tested on a specially designed wire fatigue testing fixture. The results indicate that a 1% notch is enough to reduce the fatigue resistance of the wire by 63%. Bending, twisting, and knotting of the wire did not appear to seriously affect the fatigue resistance.
