The typical displacement in suprasyndesmotic fractures is lateral, usually with the foot externally rotated. Occasionally the foot displaces secondarily into a posterior displacement.
Careful review of the x-ray images is essential for a full understanding of the mechanism of injury.
Regard the injury as a two-part fracture between the lower leg (tibia and fibula) proximally, and the foot distally. The task will be to place the foot in correct alignment with the leg.
If x-rays are not available, it is safer to correct the deformity clinically, rather than to leave it unreduced.
