The first metatarsophalangeal joint, anatomically speaking, is the big toe of the foot, and the toe bone near the first metatarsal heel is called the first metatarsophalangeal joint, and there are often a number of reasons that can cause some of its symptoms and discomfort. The most common cause is congenital factors, and then acquired factors include work and life habits, such as wearing high heels and standing for a long time. There are several types of bunions, including mild, moderate and severe. For its early treatment, wearing orthotics and wider shoes can bring the local symptoms and signs under some control. For moderate to severe bunions, surgical intervention is often required. There are many types of surgical interventions, including local orthopedic bones, ligament repair, ligament release, and lesion excision to achieve local treatment. The bunions commonly seen clinically usually occur in the first metatarsophalangeal joint.
