Flailed feet can be caused by both congenital factors and acquired maldevelopment, and depending on the patient’s condition, conservative correction or surgical correction can be adopted. Depending on the patient’s condition, there are different treatment methods, and there is no absolute best treatment method. 1. Conservative treatment (1) Manipulative repositioning: patients with mild hallux valgus can be corrected through manipulative repositioning. (2) Physical correction: Under the guidance of a professional doctor, wear a brace for correction, such as orthopedic plaster or splint for immobilization treatment. 2. Surgical correction (1) Replacement of Achilles tendon: The main purpose is to replace the Achilles tendon with the tibialis anterior muscle and peroneus longus muscle, which have good muscle strength, to increase the plantarflexion strength of the foot to correct the deformity. (2) Orthopedic surgery: If the above surgical methods are not effective in correcting hallux valgus, it is necessary to combine with orthopedic surgical treatments, such as ankle fusion, in order to restore the joint structure and function. It is recommended to consult a doctor and follow the doctor’s instructions in order to choose the appropriate treatment.
