Introduction to the outer eight characters

The main cause of splayed feet is calcium deficiency in children (vitamin D deficiency rickets). At this time, children's bones become soft due to reduced calcium deposition and excessive cartilage proliferation. In addition, children have begun to learn to walk, and the softened lower limb bones can't bear the pressure of the body like tender branches, and gradually bend and deform to form splayed feet. In addition, improper parenting methods may also lead to splayed feet, such as "wrapping candles", forcing babies to stand and walk too early or too long. Usually people walk and run with their toes forward. But some people walk and run with splayed feet inside and outside. Internal and external splayed feet refer to the toes inward or outward when walking and running. It can be divided into mild, moderate and severe internal and external splayed feet. The included angle between the medial and lateral edges of the forefoot and the longitudinal axis is less than 5 degrees, and it is mild above 5 degrees, moderate above 5 degrees, and severe above 10 degrees.
