Insert a second K-wire
A second 1.6 mm K-wire is inserted parallel to the first one into the posterior portion of the tip of the lateral malleolus.
These two parallel K-wires stabilize the fracture against rotation and will anchor the figure-of-eight wire distally.
Check the reduction under image intensification.
Care must be taken to avoid intraarticular insertion of the K-wires - check specifically with the image intensifier.
