1.What is a bunion? Bunion, also known as “big orphan disease”, is a foot deformity in which the bunion deviates outward beyond the normal physiological angle, and is one of the most common lesions of the forefoot. It is generally considered a bunion deformity when the bunion is deviated more than 15° outward. It is often accompanied by pain in the bunion area: i.e., the proximal medial end of the bunion rubs against the shoe surface, forming a bursitis, called a bunion. 2. Does every bunion need to be treated surgically? No, conservative treatment is preferred for mild bunions Where bunions are not obvious in patients with symptoms, conservative treatment can be used, allowing patients to wear wider shoes. Patients with flatfoot syndrome can use flatfoot insoles. When the patient’s local pain symptoms are obvious, walking difficulties, before considering surgery. 3.How many surgical treatments are there for bunions? First of all, minimally invasive treatment can be used for mild to moderate cases, while severe cases require osteotomy. There are more than 100 types of bunion osteotomy surgery, and more than 30 types are commonly used. The surgical plan is designed according to the degree of abnormality of the foot, especially the 1st metatarsal and phalanges, the angle of the joint surface inclination, etc., measured by X-ray. 4, the general process of foot bunion surgery The first day, for hospitalization, to do electrocardiogram, chest X-ray, foot X-ray The second day, the morning blood tests: blood, urine and fecal routine, liver and kidney function, etc., the third day, the surgery day, by the foot and ankle specialist 2-3 people, anesthesiologist 1-2 people, the operating room equipment nurse 1-2 people, a traveling nurse and other surgical team for you to perform surgery, the morning of the surgery day, no diet, by the operating room nurse Admission to the operating room. On the fourth day, the postoperative anesthesia effect usually lasts for nearly 10 hours, and pain medication may be added if necessary. You will be treated with sedative anti-inflammatory analgesia and fluid replacement. On the fifth day, crutches are usually allowed to go to the floor. The heel of the hind foot is on the ground and the forefoot avoids weight bearing. Discharge is usually possible 3-7 days after surgery, depending on wound recovery. Stitch removal is usually 2 weeks after surgery. The foot can be flushed with cool, wet water 1 week after the removal of the stitches. 5.What are the precautions for rehabilitation after bunion surgery? (1) If it is a simple surgery, you can not use crutches after surgery; if it is a complex surgery or osteotomy orthopedic surgery, you need to use crutches for 3-8 weeks after surgery, and you can put your heel on the ground. If there is an osteotomy or orthopedic operation, forefoot weight-bearing must wait for the healing of the osteotomy, usually 3 months. (2) To prevent the recurrence of bunion and to provide a relaxed environment for the healing of the medial joint capsule flap, it is generally necessary to clip a pad at the gap between the first and second toe after surgery to keep the bunion in the corrected position. The pad can be homemade from cloth or purchased as a manufactured product. The pad is usually left in place for about 3-6 weeks. (3) Possible complications of bunion surgery include: recurrence of bunion, development of bunion deformity, infection, poor incision healing, poor osteotomy healing, and bunion stiffness.
