X-ray of flat feet in adults
Authors: Mikael Häggström Flat feet is a postural deformity in which the arches of the foot collapse, with the entire sole of the foot coming into complete or near-complete contact with the ground.
Planning
Flat feet can be diagnosed clinically, but projectional radiography ("X-ray") is helpful in uncertain cases. It can be used for severity grading, although this has little implication for treatment options.[1] The talonavicular coverage angle is abnormally laterally rotated in flat feet.[2]

==Report== Report presence or absence of flat feet. To put in simpler words, an abnormally laterally rotated talonavicular coverage angle can be described as "laterally pointed navicular bone", and an abnormally decreased calcaneal pitch and abnormally downward-convex Meary's angle can be described as "fallen arch". Upon request, severity can be given (Meary's angle angle 15° - 30° is considered "moderate" flat foot, and greater than 30° is considered "severe" flat foot.), otherwise it is not necessary to report. ==Notes== {{reflist|group="note"| refs= Detailed explanations and references are located in the Calcaneal pitch article.
