There are more than ten types of bunion osteotomies that are popular in China, and the choice of the procedure should be based on the measured bunion angle and intermetatarsal angle. When the intermetatarsal angle is less than 15 degrees, the distal end of the first metatarsal bone can be osteotomized, and Chevron osteotomy is commonly used. When the intermetatarsal angle is greater than 15 degrees, the first metatarsal cadre osteotomy or the proximal osteotomy of the first metatarsal can be performed, and the commonly used osteotomies are Scarf osteotomy and Ludloff osteotomy. If the bunion angle is large, an Akin osteotomy can be performed to correct the bunion angle. If the medial metatarsophalangeal joint is also unstable, a Lapidus osteotomy can be performed for fusion.
