There are many methods of surgical osteotomy for bunions, the common ones are as follows: First, osteotomy of the first metatarsal bone, this type of osteotomy is performed for the base of the first metatarsal bone in the proximal segment, and a wedge-shaped block is removed to correct the shape of the bunion. Secondly, the osteotomy around the first metatarsal bone can be divided into many categories, and only the medial side of the first metatarsal head can be osteotomized. In addition to this, wedge osteotomy and rotational osteotomy of the first metatarsal can also be done. A wedge osteotomy is a wedge-shaped osteotomy of the middle part of the first metatarsal to achieve orthopedic purposes. A rotational osteotomy is a complete lateral amputation of the first metatarsal, followed by rotation of the fracture end and subsequent fixation of the fracture end with an internal fixation device, which can also achieve better results.
