The treatment of bunions is as follows: First, conservative treatment: mild bunions can be treated conservatively by using a bunion brace, such as placing the brace between the first toe and the second toe to apply an inward force to the overturned bunion, which can correct the bunion deformity and reduce the protrusion of the first metatarsal. Secondly, surgical treatment: bunion cut can be performed, along with the tightening of the medial joint capsule of the first metatarsophalangeal joint and the V-shaped osteotomy of the distal end of the first metatarsal bone, through this triple surgery can completely correct the bunion and solve the protrusion of the solitary foot abduction.
