Indication for tension band wiring
The tension band wiring is indicated for fixation of small medial fragments, avulsion fractures, or osteoporotic bone.
Tension band principle
The tension band converts tensile forces into compression forces.
To be able to use a tension band, the opposite cortex needs to have contact and be able to resist compression.
The figure-of-eight wire loop lies on the medial (tension) surface of the medial malleolus and acts as a tension band when tightened.
Choose a wire of sufficient strength to withstand the tensile forces generated in the figure-of-eight loop (0.8 - 1.0 mm).
