Preparing the K-wire
![Preparing the K-wire]()
Soundsettings A K-wire with a diameter of 2 mm is used. To reduce the risk of perforation of the thin cortical bone of the metacarpal head, it is introduced with the blunt tip. Prior to this, the distal blunt tip is bent upwards by about 20 degrees with pliers. For better handling, the proximal end of the wire is bent 90 degrees in the same plane. This allows better control of the direction of insertion.
