Drilling

Drill an antero-posterior hole with the 2.0 mm drill bit and protection sleeve, transverse to the long fibular axis, approximately 3 cm proximal to the fracture.

Keep soft-tissue dissection to a minimum.

Pearl

In osteoporotic bone, to avoid cutting out of the wire from the drill hole, a bicortical screw may be used as an alternative means of anchoring the proximal end of the wire.

Wire preparation and insertion

Prepare the 0.8 mm wire by making a loop approximately one third along its length.

Insert the shorter segment of the wire through this drill hole.

Figure-of-eight configuration

The small pointed reduction forceps can now be removed.

Pass the long segment of the wire (bearing the loop) in a figure-of-eight configuration around the protruding ends of the K-wires.

Twist the free ends of the wire firmly together.

Pearl

Some surgeons prefer to use two pieces of wire, twisting the ends together to create the figure of eight loop with a twist on each side.

Tightening the wire

The wire twist is loosely prepared ensuring that each end of the wire spirals equally, forming a double helix – avoid twisting one wire around the other (straight) wire.

The wire is tensioned by pulling on the twists.

The slack is then taken up by further twisting. Repeat this until the desired tension is achieved. Both loops must be tightened at the same time and in the same direction, to achieve equal tension on both arms of the wire.

Note

In osteopenic bone care must be taken to avoid excessive tensioning.

Prevent later soft-tissue irritation

Trim the twists and turn the ends towards the fibula in order not to irritate the soft-tissues later.

Sinking the K-wires

Cut the 2 K-wires obliquely approximately 1 cm from their insertion points and, with the help of a bending iron and forceps, bend through 180 degrees.
The K-wires are then driven home, sinking their curved ends into the bone in order to prevent backing out and skin injury.

Take final x-rays in both planes to check results.
