Flatfoot syndrome is a congenital or postural deformity resulting in low arch, foot soft tissue laxity, and heel exostosis.
I. Causal factors of congenital flatfoot syndrome 1, the foot pars plana, foot navicular nodes are too large, the posterior tibial muscle attachment is weak.
2.The 1st metatarsal bone is short, and the other metatarsal bones bear too much gravity, which promotes the flattening of the foot arch.
3.Chondrogenic or fibrous joint between the tarsal bones of the foot.
Second, the acquired pathogenic factors 1, the feet long-term weight-bearing standing, weight increase, long-distance travel over fatigue, maintain the arch muscles, ligaments, joint capsule and tendon membrane and other soft tissues gradually weakened, the arch gradually low flat.
2, long-term illness bedridden, lack of exercise, muscle atrophy, tension weakening, weight-bearing arch sagging.
3, wearing improper shoes, the heel is too high, long-term weight forward, the heel bone is tilted forward and down, the longitudinal arch of the foot is destroyed.
4, foot bone disease, such as rheumatoid arthritis, bone and joint tuberculosis, etc.
5, polio sequelae flatfoot disease.
