I have summarized the bunion-related consultations over the past six months, and have divided them into three parts: pre-visit, pre-operative and post-operative, in the hope of bringing more convenience to your consultation and treatment, and hoping that patients will recover soon. Q1: What is a bunion? A: Bunion, commonly known as bigfoot, is a common disease of the foot, mainly characterized by deformity and pain. It is characterized by bunions, subluxation of the interphalangeal joint and medial formation of bunions, and difficulty in wearing shoes. When the root of the big toe (actually the first metatarsal) is internally displaced, it makes the area extremely elevated and prone to friction with shoes. Over time, the skin and subcutaneous related tissues in the area thicken, become red and swollen, and bursae form, resulting in bunions. Q2: Why do I get bunions? A: 1. Genetic factors: About half of the patients have genetic factors. The occurrence of foot bunions is mainly caused by certain defects in the bones and ligaments that make up the foot.2. Long periods of standing and walking can aggravate ligament damage and contribute to the onset or accelerate the development of the condition.3. Often wear pointed shoes or high heels: the front of pointed shoes is triangular, forcing the front of the foot to be forced into a narrow triangular area, plus the upper of the shoe is leather without elasticity, forcing the bunion to turn outward and the little toe to turn inward. The little toe is turned inward. High-heeled shoes make the foot bear more pressure, and the ligaments at the joints are excessively stretched, resulting in bunions. In addition, patients with flat feet are more likely to develop bunions. When bunions are severe, the second toe can be squeezed to the dorsal side by the bunion, forming a hammer finger. Q3: What kind of bunion needs surgery? A: Patients with severe bunion deformity, medial bunion formation, or combined interphalangeal joint subluxation, callus formation under the second and third metatarsal heads and hammertoe deformity, with significant pain and difficulty in wearing shoes, which affects daily work life, are recommended to undergo surgery. Q4: What is small incision osteotomy? A: It is a new method of combining Chinese and Western medicine to treat bunions and other foot deformities with small incisions and manipulation, using a minimally invasive technique of local anesthesia and external fixation with “8” bandages. It establishes the advantages of small incision, little damage, less pain, no stitches, self-care after surgery, fast recovery, satisfactory orthopedic, no recurrence of deformity, no obvious complications, low cost, etc. It solves the problems of traditional surgery, and is also the best method for treating painful corpus callosum (foot pad), painful corns, small toe deformity, heel pain and other foot diseases.
