In clinical practice, patients with flat feet can develop valgus deformity if they are normally overactive, overworked or strained in the bunion area. When this deformity occurs, the first step is to instruct the patient to take rest, reduce the amount of activity, and avoid adverse factors such as strain and strain. If the bunion angle is not severe, conservative treatment can be considered by performing traditional Chinese medicine techniques to correct the bunion and then wearing a bunion brace to continue fixation. If the bunion angle is more than 12 degrees, surgical treatment is an option. Minimally invasive surgery can be performed to remove the bunion, or to remove the hyperplasia and then correct the force line of the bunion; traditional incisional wedge osteotomy of the bunion can also be performed.
