There are more than a hundred surgical treatment modalities for bunions, each of which is different. The goal of surgical treatment is to relieve the patient’s pain-based symptoms and restore the function of the forefoot, followed by the correction of the deformity. The choice of surgery is based on the patient’s pathological changes, combined with the patient’s age, physical condition, working life needs and other factors. Before surgery, weight-bearing radiographs of both feet should be taken to understand the size of the bunion angle, intermetatarsal angle (IMA), interphalangeal angle (IPA), proximal joint fixation angle (PASA), distal joint fixation angle (DASA), and metatarsal wedge angle, as well as to understand the joint adaptability and the length difference between the distal ends of the 1st and 2nd metatarsals to determine the severity of the bunion. In the case of simple HVA enlargement, surgery is divided into two types: soft tissue reconstruction surgery and bony Akin surgery. For IMA enlargement, the treatment is a variety of 1st metatarsal osteotomy with soft tissue reconstruction. For PASA enlargement, the treatment is Chevron-Gerbert surgery with soft tissue reconstruction. For the MCA enlargement type, Lapidus surgery with soft tissue reconstruction is used. For the osteoarthritic type, artificial joint replacement or metatarsophalangeal joint fusion has been advocated in recent years. For the compound type, multiple surgeries are required.
