Minimally invasive spine surgery, joint surgery and trauma surgery are now flourishing at home and abroad. Combining the characteristics of foot and ankle surgery and the new progress of foreign counterparts, we are the first to propose the concept of minimally invasive foot and ankle surgery in China. Is it a small incision bunion surgery? Minimally invasive foot and ankle surgery is a large category, which is a comprehensive use of minimally invasive resources for forefoot, midfoot, rearfoot and ankle surgery, involving humanities, technology, psychology, medical ethics and many other aspects, and is the embodiment of high-quality medical treatment, of which arthroscopy, external fixation frame and percutaneous surgery are important elements, far from the traditional sense of small incision “minimally invasive” bunion surgery. Twenty years ago, appendix, gallbladder, uterine fibroids, prostate enlargement and other disorders were all subjected to incisional surgery. At present, doctors in the field of foot and ankle surgery generally have no more problems doing open surgery, but minimally invasive surgery is more demanding, and not many people master this series of techniques, don’t know, won’t know and won’t learn, so there will be people who always try to muddy the water and deliberately confuse it with small incision bunion surgery. 2.What can minimally invasive foot and ankle surgery do? What are the advantages compared to traditional incision surgery? Minimally invasive foot and ankle surgery technology can replace most of the traditional incisional surgeries. The name and type of surgery are the same, but it can provide patients with exact results, less trauma, less pain and swelling, and faster recovery. The procedure can benefit patients in the areas of ankle and subtalar joint fusion, bunion, hammertoe, high arched foot, talar cartilage injury, tarsal sinus syndrome, stopping point Achilles tendonitis, minimally invasive flatfoot correction, minimally invasive tendon transposition and sports injuries. For example, the classic foreign ankle fusion and subtalar fusion require large incisions and stripping, which can cause a lot of damage, and patients complain a lot about postoperative pain and swelling, whereas minimally invasive arthroscopic joint fusion surgery only requires the establishment of a channel without extensive incision and stripping, which can reduce trauma by 80-90% and significantly improve patients’ quality of life after surgery. Minimally invasive surgery requires expensive equipment and instruments and high requirements for doctors’ expertise, so the future medical market segmentation of this technology means high level and expensive, and the service targets are mainly high-end people, and the cost is likely to be tens of times of the traditional open surgery cost. 3. Doctors should listen to the reasonable demands of patients and put patient safety in the first place. Minimally invasive is what all patients want, but it may not be suitable for every patient, and requires comprehensive consideration by doctors. I have an objective understanding of minimally invasive foot and ankle surgery and should give full play to its advantages, but I am against the superstition of minimally invasive and cannot do minimally invasive just for the sake of doing it. Minimally invasive surgery can be done if you meet the conditions, but traditional incisional surgery should be done if you don’t.
