In clinical practice, bunions often occur due to hereditary factors in most cases and secondary factors in a few cases. In clinical practice, patients with bunions usually need to take X-rays to make a diagnosis, which can be done by taking orthopantomograms of the bunion. This can be done by taking an orthostatic radiograph of the bunion. The specific measurements are the axis of the bunion’s phalanx and then the axis of the 1st metatarsal; if the angle of intersection of the two lines is more than 12° or 15°, then the bunion is considered to be a bunion. If the angle of intersection of the two lines exceeds 12° or 15°, the diagnosis of a bunion is confirmed. The axis of the bunion and the metatarsal bone of the 2nd toe can also be measured. A definitive diagnosis can be made by taking x-rays and combining them with a clinical examination. Patients with bunion should consult the doctor in a timely manner, and should not do anything on their own to avoid delayed treatment and further aggravation of the condition.
