A bunion is a bone deformity of the foot and ankle that should be treated by a medical professional. This deformity has a characteristic that only surgery can solve it and no longer recur, other treatments are ineffective, and the brace only delays the progress of the deformity, so why not do surgery sooner or later. There are two types of surgery to correct this deformity: one is the small, minimally invasive incision that is currently all over the place, which is simple, but because it is not a direct vision osteotomy, like a doctor operating blindfolded, all based on feeling, so the doctor’s touch is extremely critical, and there are not many people in the country who can do a good job. But bunion shortening, post-operative walking pain and the probability of deformity recurrence is much greater, there is a little benefit, the incision is small (should be less than 1cm). It is only suitable for patients with a simple, mild deformity. Post-operative review is extremely critical and constant adjustment is required. The main idea is to cut off the deformed metatarsal bone with a special swing saw under direct vision after the incision, depending on the characteristics of the deformity, it can be broken in 2 or 3 sections, and then fixed with plate screws, and then remove the steel nails after the bone heals. This surgical method is a complete orthopedic solution for all deformities at once, with good results and basically no recurrence, and some doctors may not be able to correct the deformity enough during the osteotomy, but it is not a problem with this method. At present, this is also the mainstream method abroad. In the major foot and ankle surgery conferences held in China, this is the procedure as long as it is related to bunions, and we discuss each other’s experience and perfect the procedure. This is also the procedure in the leading foreign foot and ankle journals, called hallux valgus, but it must not be possible in private hospitals, nor in general orthopedic specialties. How to choose the timing of surgery for bunion patients is a very specialized issue. Deformity and pain are sometimes not proportional, and the timing of surgery varies from person to person. But there is a simple principle: 1, no pain, no obvious symptoms, regardless of deformity, can temporarily do not do surgery (except for severe deformity resulting in difficulty in wearing shoes); 2, symptoms, pain is not severe, to consider surgery, deformity is not back, will only get heavier, but not necessarily immediately do, generally should be in deformity or pain significantly aggravated as soon as possible before surgery, if the deformity is stable for a long time, can Do or do not do; 3, pain severe, must do, do not tolerate, more than 90 years old also did, the effect is very good, this orthopedic surgery can completely achieve the effect of pain-free walking, the current recurrence of the possibility of almost no, tolerate to the age of surgery risk is also large, the quality of life is affected year-round, not worth it.
