The DynaNite FlexWire is a two-zone nitinol wire that takes advantage of the superelastic properties of nitinol to improve upon standard K-wire fixation for hammertoe correction. Broken and bent wires are common complications with standard K-wire fixation.1 The superelastic properties of the implanted zone of this wire allow for the same correction surgeons are accustomed to with stainless steel wires, but with the advantage of reducing the risk of permanently bent wires in noncompliant patients. The bendable portion left outside of the toe can be bent, cut, and capped in standard fashion.

The FlexWire is offered in 0.86 mm, 1.1 mm, and 1.6 mm diameters.
