[0002] Hallux valgus refers to a deformity in which the toes of the foot tilt outward at a greater than physiological angle of 15°. The main cause is dislocation of the joint at the base of the big toe, which causes the big toe to bend outward and the big toe bone to protrude outward. In addition to squeezing other toes, it is also easy for friction due to wearing shoes to cause swelling and inflammation on the inner or dorsal side of the big toe joint, and thick skin and bursa are easily formed on the outside of the protruding bone, causing permanent deformation of the toes and pain. Once you have the disease, it cannot be recovered without treatment.
