The technique of bunion osteotomy orthopedic surgery is mature and the results are ideal, and there are usually few sequelae. However, there are a few people who have sequelae due to the technical level of the surgeon and the individual differences of the patient, such as patients with severe disease, combined with arthritis, joint collapse or other underlying diseases. The first one is ischemia, necrosis, and collapse of the metatarsal head. Due to the osteotomy, the bones are realigned after transposition, which is equivalent to fracture rehealing, resulting in poor local blood circulation. After prolonged walking, ischemia and necrosis of the metatarsal head will occur, and prolonged pressure will lead to ischemia, necrosis and collapse of the metatarsal head, thus affecting walking. The second one is the recurrence of bunion, which is relatively rare. The recurrence of bunion may occur because the soft tissue tension is not adjusted after osteotomy or the dislocated seed bone is not treated, which is also rare. Thirdly, elevation of the metatarsal bones, including the 1st and 2nd metatarsal bones, can cause a shift of the negative focus and produce walking pain. This can be corrected with a shortening of the metatarsal bones or a lowering of the metatarsal bones through a second-stage surgery and a new osteotomy. All in all, osteotomies for bunions are mature and effective and can be performed.
