1.25 mm Guide Wire for 3.5/4.0 mm Cannulated Screws
1.25 mm guide wires used with 3.5 mm and 4.0 mm cannulated screws may bend during insertion and even break. This can occur, for example, in foot surgery. Therefore, the existing 1.25 mm guide wire is now available in a new, stiffer, and higher yield strength material that is less likely to fail in clinical applications (compared to 316L). The material, MP35N, is a cobalt alloy. Galvanic corrosion was tested (in the case of breakage of a guide wire which would remain in the body and in contact with a titanium plate). There was only a low-level driving force. The resulting current was too low to create corrosion.
The greater stiffness increases the wires tolerance to bending before permanent deformation and better resists cutting of the wire during drilling.
The new guide wires are available threaded and nonthreaded.
