As the saying goes, “A journey of a thousand miles begins with the foot.” For middle-aged and elderly people who have foot problems and cannot live and walk normally, their greatest wish is to have a healthy pair of feet! In the hospital, bunions (big bone heel), painful corpus callosum (foot pad), painful corns, small toe deformity, heel pain and nail fungus are the most common foot diseases seen in patients. The most common is bunion deformity, and it is more common in women. The cause of bunions is the discomfort of wearing shoes, most elderly women have a history of wearing tight shoes or high heels; in addition, the occurrence of bunions is related to genetic factors, and there are certain defects in the structure of the foot (i.e., the bones of each part of the foot), which are inherent factors in the formation of bunions. The main manifestations of bunions are deformity and pain. They are characterized by bunions, subluxation of the interphalangeal joint and the formation of bunions on the medial side, making it difficult to wear shoes. Over time, it can be complicated by submetatarsal head callus and hammertoe deformity of the second and third feet. Its discordant protrusion, which is constantly squeezed and rubbed by shoes, makes the bunion more and more obvious and can become inflamed in severe cases, which is the greatest pain for patients. In the past, the purpose of treating bunions was mainly to relieve pain, and correction was not advocated for painless or painless deformities. With the improvement of the living standard of the elderly, most patients visit the clinic not only to relieve the pain, but also to correct the foot deformity and choose their favorite shoes to meet the requirements of life. In a metropolis like Beijing, this is more common due to the high incidence of bunions and has contributed to our research on bunions. Due to the different requirements for the treatment of bunions, there are as many as one or two hundred different procedures for the correction of bunions. They are mainly divided into traditional surgery with large incisions and modern foot surgery with minimally invasive small incisions; however, the efficacy of the previous traditional surgery is not satisfactory, and there are problems such as complicated anesthesia, large incisions, large injuries, recurrence of deformities, and visible complications, large impact on forefoot biomechanics, and the need for internal fixation or external fixation in plaster.
