Experts pointed out that "Bigfoot", scientifically known as "hallux valgus", is a common foot deformity, which is characterized by redundant osteophyte above the toe, which is more common in female friends (male ratio is about 1: 40) and is mostly symmetrical. Most of them are genetic factors (about 80%). Wearing pointed shoes, narrow shoes or high heels for a long time, standing for too long and walking too much are the common causes of hallux valgus. Large foot bones not only affect the beauty of the foot, but also deform when wearing shoes, accompanied by bunions and pain, and often complicated with toe deformities such as foot pads, corns and claw toes. In severe cases, walking pain is unbearable, and it gets worse with age. Bigfoot pain indicates a serious condition, which may affect walking ability if left untreated. At present, one of the best surgical methods to treat the big foot bone is "minimally invasive surgery", which avoids the shortcomings of previous surgical methods, smoothes osteophyte through micro-incision, corrects deformed toes, and makes the foot shape return to normal and beautiful. This surgical method is suitable for the treatment of various foot deformities. Advantages of minimally invasive and painless correction of the big foot bone: 1, minimally invasive and painless: small trauma, small incision, no pain during operation, no damage to joints and other surrounding tissues, and no scar after operation. 2, the operation time is short: according to the serious procedure of the big foot bone, the operation of one foot can be completed in half an hour, which is easy and safe, without hospitalization, no side effects and no influence on walking. 3. Satisfactory results: All patients were analyzed and located before and after operation, and the postoperative appearance was beautiful, which fundamentally avoided recurrence.
