The causes of bunions are complex and varied and require comprehensive analysis to determine whether minimally invasive bunion surgery is possible. Mild and moderate bunions are generally minimally invasive. In severe cases, a traditional osteotomy should be used to correct the bunion. In some cases, the bunion is caused by hereditary factors. In some women, bunions may be caused by prolonged wearing of high heels. Bunions can also be caused by joint development or fusion deformities caused by fractures or infections. If a bunion is not particularly serious, it can usually be treated with minimally invasive surgery. The minimally invasive treatment of bunion can be done by removing the bony residue on the inside of the bunion, cutting off the phalanx, and pushing the bunion bone outward to correct the bunion, which takes less time and causes less localized damage. Usually, we should pay attention to relaxation and rest, choose suitable loose shoes, and also actively exercise. Minimally invasive surgery has strict indications, and is suitable for mild and moderate bunions, but not for severe bunions. Most severe bunions require traditional osteotomies, which involve soft tissue release and osteotomies to improve symptoms. The actual condition of the bunion should be determined by the cause of the bunion, and the correct treatment plan should be chosen under the guidance of the doctor.
