One cause of digitus valgus and hallux valgus is thought to be changes in the abductor hallucis muscle brought about by the application of external force.

The external force placed on the big toe and little toe causes the toes to turn medially and places a burden on the abductor hallucis muscle, and the ligaments are stretched and tired, resulting in insufficient strength to return the toes to their original position.

Toes are important for actions using the foot.

If they are not functioning properly, a burden is incurred when walking or running.

Since these activities are invariably performed on a daily basis, we believe this to be a cause of gradual buildup of burden and digitus valgus or hallux valgus.
