Minimally invasive bunion treatment methods mainly include the following categories: 1. Surgery that only removes bony or soft tissue growths, the main principle of which is to reach the lesion on the inner side of the first metatarsophalangeal joint, and then do appropriate cleanup to achieve a change in the shape of the bunion; 2. Surgery that balances the soft tissues, which may require a small incision on the inner and outer side of the first metatarsophalangeal joint, and then do appropriate balancing surgery on soft tissues, ligaments, etc., on both sides; 3. Surgery; 3. Osteotomies around the first metatarsophalangeal joint, such as osteotomies at the base of the first phalangeal muscle or rotational osteotomies of the first metatarsal; 4. Compound surgeries of the above mentioned surgeries, which are slightly more traumatizing than the previous ones.
