The weightbearing lateral foot radiograph is important in the assessment of foot alignment and the diagnosis of abnormalities that cause malalignment and foot pain. Nonweightbearing views (e.g. oblique foot radiograph) are inadequate for the assessment of alignment because the bones of the feet are not in their functional state 1.
The foot is planted on a solid surface with the lower leg perpendicular to the floor (weightbearing surface). The cassette or detector plate is held parallel to the axis of the foot and the central beam is directed through the foot perpendicular to the axis of the foot (and the detector).
In nonambulatory patients, such as young children, simulated weightbearing can be achieved with a plastic board 1.
